SERVICING PRECAUTIONS



CAUTION: Before servicing receivers covered by thisservice manual and its supplements and addenda, readand follow the SAFETY PRECAUTIONS on page 3 of thispublication.NOTE: If unforeseen circumstances create conflictbetween the following servicing precautions and any of thesafety precautions on page 3 of this publication, alwaysfollow the safety precautions. Remember: Safety First.

General Servicing Precautions1. Always unplug the receiver AC power cord from the AC

power source before;a. Removing or reinstalling any component, circuit

board module or any other receiver assembly.b. Disconnecting or reconnecting any receiver electrical

plug or other electrical connection.c. Connecting a test substitute in parallel with an

electrolytic capacitor in the receiver.CAUTION: A wrong part substitution or incorrectpolarity installation of electrolytic capacitors mayresult in an explosion hazard.

d. Discharging the picture tube anode.2. Test high voltage only by measuring it with an

appropriate high voltage meter or other voltagemeasuring device (DVM, FETVOM, etc) equipped witha suitable high voltage probe.Do not test high voltage by "drawing an arc".

3. Discharge the picture tube anode only by (a) firstconnecting one end of an insulated clip lead to thedegaussing or kine aquadag grounding system shieldat the point where the picture tube socket ground leadis connected, and then (b) touch the other end of theinsulated clip lead to the picture tube anode button,using an insulating handle to avoid personal contactwith high voltage.

4. Do not spray chemicals on or near this receiver or anyof its assemblies.

5. Unless specified otherwise in this service manual,clean electrical contacts only by applying the followingmixture to the contacts with a pipe cleaner, cotton-tipped stick or comparable non-abrasive applicator;10% (by volume) Acetone and 90% (by volume)isopropyl alcohol (90%-99% strength)CAUTION: This is a flammable mixture.Unless specified otherwise in this service manual,lubrication of contacts in not required.

6. Do not defeat any plug/socket B+ voltage interlockswith which receivers covered by this service manualmight be equipped.

7. Do not apply AC power to this instrument and/or any ofits electrical assemblies unless all solid-state deviceheat sinks are correctly installed.

8. Always connect the test receiver ground lead to thereceiver chassis ground before connecting the testreceiver positive lead.Always remove the test receiver ground lead last.

9. Use with this receiver only the test fixtures specified inthis service manual.CAUTION: Do not connect the test fixture ground strapto any heat sink in this receiver.

Electrostatically Sensitive (ES) DevicesSome semiconductor (solid-state) devices can bedamaged easily by static electricity. Such componentscommonly are called Electrostatically Sensitive (ES)Devices. Examples of typical ES devices are integratedcircuits and some field-effect transistors andsemiconductor "chip" components. The followingtechniques should be used to help reduce the incidence ofcomponent damage caused by static by static electricity.1. Immediately before handling any semiconductor

component or semiconductor-equipped assembly, drainoff any electrostatic charge on your body by touching aknown earth ground. Alternatively, obtain and wear acommercially available discharging wrist strap device,which should be removed to prevent potential shockreasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped withES devices, place the assembly on a conductivesurface such as aluminum foil, to prevent electrostaticcharge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder orunsolder ES devices.

4. Use only an anti-static type solder removal device.Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient todamage ES devices.

5. Do not use freon-propelled chemicals. These cangenerate electrical charges sufficient to damage ESdevices.

6. Do not remove a replacement ES device from itsprotective package until immediately before you areready to install it. (Most replacement ES devices arepackaged with leads electrically shorted together byconductive foam, aluminum foil or comparableconductive material).

7. Immediately before removing the protective materialfrom the leads of a replacement ES device, touch theprotective material to the chassis or circuit assemblyinto which the device will be installed.CAUTION: Be sure no power is applied to the chassisor circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise harmless motionsuch as the brushing together of your clothes fabric orthe lifting of your foot from a carpeted floor cangenerate static electricity sufficient to damage an ESdevice.)

General Soldering Guidelines1. Use a grounded-tip, low-wattage soldering iron and

appropriate tip size and shape that will maintain tiptemperature within the range or 500 F to 600 F.

2. Use an appropriate gauge of RMA resin-core soldercomposed of 60 parts tin/40 parts lead.

3. Keep the soldering iron tip clean and well tinned.4. Thoroughly clean the surfaces to be soldered. Use a

mall wire-bristle (0.5 inch, or 1.25cm) brush with ametal handle.Do not use freon-propelled spray-on cleaners.

5. Use the following unsoldering techniquea. Allow the soldering iron t ip to reach normal

temperature.(500 F to 600 F)

b. Heat the component lead until the solder melts.c. Quickly draw the melted solder with an anti-static,

suction-type solder removal device or with solderbraid.CAUTION: Work quickly to avoid overheating thecircuitboard printed foil.

6. Use the following soldering technique.a. Allow the soldering iron tip to reach a normal

temperature (500 F to 600 F)b. First, hold the soldering iron tip and solder the strand

against the component lead until the solder melts.

c. Quickly move the soldering iron tip to the junction ofthe component lead and the printed circuit foil, andhold it there only until the solder flows onto andaround both the component lead and the foil.CAUTION: Work quickly to avoid overheating thecircuit board printed foil.

d. Closely inspect the solder area and remove anyexcess or splashed solder with a small wire-bristlebrush.

IC Remove/ReplacementSome chassis circuit boards have slotted holes (oblong)through which the IC leads are inserted and then bent flatagainst the circuit foil. When holes are the slotted type,the following technique should be used to remove andreplace the IC. When working with boards using thefamiliar round hole, use the standard technique asoutlined in paragraphs 5 and 6 above.

Removal1. Desolder and straighten each IC lead in one operation

by gently prying up on the lead with the soldering irontip as the solder melts.

2. Draw away the melted solder with an anti-staticsuction-type solder removal device (or with solderbraid) before removing the IC.

Replacement1. Carefully insert the replacement IC in the circuit board.2. Carefully bend each IC lead against the circuit foil pad

and solder it.3. Clean the soldered areas with a small wire-bristle

brush. (It is not necessary to reapply acrylic coating tothe areas).

"Small-Signal" Discrete TransistorRemoval/Replacement1. Remove the defective transistor by clipping its leads as

close as possible to the component body.2. Bend into a "U" shape the end of each of three leads

remaining on the circuit board.3. Bend into a "U" shape the replacement transistor leads.4. Connect the replacement transistor leads to the

corresponding leads extending from the circuit boardand crimp the "U" with long nose pliers to insure metalto metal contact then solder each connection.

Power Output, Transistor DeviceRemoval/Replacement1. Heat and remove all solder from around the transistor

leads.2. Remove the heat sink mounting screw (if so equipped).3. Carefully remove the transistor from the heat sink of the

circuit board.4. Insert new transistor in the circuit board.5. Solder each transistor lead, and clip off excess lead.6. Replace heat sink.

Diode Removal/Replacement1. Remove defective diode by clipping its leads as close

as possible to diode body.2. Bend the two remaining leads perpendicular y to the

circuit board.3. Observing diode polarity, wrap each lead of the new

diode around the corresponding lead on the circuitboard.

4. Securely crimp each connection and solder it.5. Inspect (on the circuit board copper side) the solder

joints of the two "original" leads. If they are not shiny,reheat them and if necessary, apply additional solder.

Fuse and Conventional ResistorRemoval/Replacement1. Clip each fuse or resistor lead at top of the circuit board

hollow stake.2. Securely crimp the leads of replacement component

around notch at stake top.3. Solder the connections.

CAUTION: Maintain original spacing between thereplaced component and adjacent components and thecircuit board to prevent excessive componenttemperatures.



Circuit Board Foil RepairExcessive heat applied to the copper foil of any printedcircuit board will weaken the adhesive that bonds the foilto the circuit board causing the foil to separate from or"l i f t-off" the board. The following guidelines andprocedures should be followed whenever this condition isencountered.

At IC ConnectionsTo repair a defective copper pattern at IC connections usethe following procedure to install a jumper wire on thecopper pattern side of the circuit board. (Use thistechnique only on IC connections).

1. Carefully remove the damaged copper pattern with asharp knife. (Remove only as much copper asabsolutely necessary).

2. carefully scratch away the solder resist and acryliccoating (if used) from the end of the remaining copperpattern.

3. Bend a small "U" in one end of a small gauge jumperwire and carefully crimp it around the IC pin. Solder theIC connection.

4. Route the jumper wire along the path of the out-awaycopper pattern and let it overlap the previously scrapedend of the good copper pattern. Solder the overlappedarea and clip off any excess jumper wire.

At Other ConnectionsUse the following technique to repair the defective copperpattern at connections other than IC Pins. This techniqueinvolves the installation of a jumper wire on thecomponent side of the circuit board.1. Remove the defective copper pattern with a sharp

knife.Remove at least 1/4 inch of copper, to ensure that ahazardous condition will not exist if the jumper wireopens.

2. Trace along the copper pattern from both sides of thepattern break and locate the nearest component that isdirectly connected to the affected copper pattern.

3. Connect insulated 20-gauge jumper wire from the leadof the nearest component on one side of the patternbreak to the lead of the nearest component on theother side.Carefully crimp and solder the connections.CAUTION: Be sure the insulated jumper wire isdressed so the it does not touch components or sharpedges.

DESCRIPTION OF BLOCK DIAGRAM



1. Video Controller Part.This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to thedigital video signal using a pixel clock.The pixel clock for each mode is generated by the PLL.The range of the pixel clock is from 25MHz to 165MHz.This part consists of the Scaler, ADC and TMDS receiver .The Scaler gets the video signal converted analog to digital, interpolates input to 1920 x 1200 resolution signal andoutputs 8-bit R, G, B signal to transmitter.

2. Power Part.This part consists of the 3.3V and 1.8V regulator to convert power which is provided 5V,5V in Power board and Micom5V is provided for LCD panel.(W2600H-PFS)12V is used for LPL LCD Panel Power.(W2600HP-BNS)

3. MICOM Part.This part consists of EEPROM IC which stores control data and the Micom.The Micom distinguishes polarity and frequency of the H/V sync are supplied from signal cable.The controlled data of each modes is stored in EEPROM.

*refer to the each frequency of crystal oscillators and working frequency.Video processor : 14.31818MHz.USB Hub : 30MHzLVDS Clock Freq. : 154MHz MEMORY Clock Freq. : 183MHz

Operation description_Power

1. EMI components.This part contains of EMI components to comply with global marketing EMI standards like FCC,VCCI CISPR, thecircuit included a line-filter, across line capacitor and of course the primary protection fuse.

2. Input rectifier and filter.This part function is for transfer the input AC voltage to a DC voltage through a bridge rectifier and a bulk capacitor.

3. Energy Transfer.This part function is for transfer the primary energy to secondary through a power transformer.

4. Output rectifier and filter.This part function is to make a pulse width modulation control and to provide the driver signal to power switch, toadjust the duty cycle during different AC input and output loading condition to achieve the dc output stabilized, andalso the over power protection is also monitor by this part.

5. Photo-Coupler isolation.This part function is to feed back the DC output changing status through a photo transistor to primary controller toachieve the stabilized DC output voltage.

6. Signal collection.This part function is to collect the any change from the DC output and feed back to the primary through phototransistor.
