REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

HOW TO DISASSEMBLE & REASSEMBLE BOARDS TO A PLASMA DISPLAY

HOW TO DISASSEMBLE & REASSEMBLE BOARDS TO A PLASMA DISPLAY


DISASSEMBLING & REASSEMBLING
Disassembling & Re-assembling of FPC (Flexible Printed Circuit) and Y-Buffer(Upper and Lower).
Removal procedures.
Full out the FPC from Connector by holding the lead of the FPC with hands.
CLICK ON THE PICTURES TO ZOOM
Assembling Procedures.
Push the lead of FPC with same strength until to be connected completely.
Note: Be careful do not get a damage on the connector pin during connecting by mistake.
Assembling & Disassembling of Flat Cable Connector of X-Main Board.
Disassembling Procedure.
Pull out the clamp of connector.
Pull Flat cable out press down lightly.
Turn the Flat cable reversal.
Assembling Procedure.
Put the Flat cable into the connector press down lightly until locking sound (“Dack”) comes out.
Assembling & Disassembling the FFC and TCP from Connector.
Disassembling of TCP
Open the clamp carefully.
Pull the TCP out from Connector.
Assembling of TCP
Put the TCP into the Connector carefully.
Close the clamp completely. ( The sound (“ Dack”) comes out.)
Notes : TCP and Connector was connected surely.
Checking whether the foreign material is on the Connector inside before assembling of TCP.
Be careful do not get a damage on the board by ESD during handling of TCP.
Misassembling of TCP
The misassembled of TCP is the cause of defect.
Checking method of misassembled of TCP.
  • Disconnecting H3 from CN8006 of LBE.
  • Whether H8 and H9 are connected.
  • Checking the resistance between Pin 1 and 5.
  • Resistance > a few [ KOhm] :OK
  • Resistance < 20 Ohm : At least, more than 1pc of TCP is wrong.
Assembling & Disassembling of FFC
The procedure of assembling and disassembling of FFC is the same as TCP.
