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.

PANASONIC PLASMA 10 BLINKS FAULT – PANASONIC PLASMA TV – 9TH GENERATION PLASMA TVS

10 Blinks fault – Panasonic Plasma TV – 9th Generation Plasma TVs


The unit goes shut down, and the standby LED blinks 10 times
When the power LED blinks 10 times right after the TV has been plugged-in into the AC line and the Power is OFF, the P, the PA, the DG, the H, or the DT may be defective.
The DT, DG, and H board are part of the assembly. For troubleshooting, the DT board must be removed.
To rule out the H board:
Disconnect connector H40 and plug the TV into the AC line
Note: If the Power LED stops blinking, the H board may be defective.  If the power LED still blinks, See the next.
Keep in mind, every time the H board is suspected to be defective, change both the PA and the H board at the same time before applying power to the unit.
To rule out the DT board (Digital Tuner)
1. Remove the screws securing the DT board. Plug the TV into the AC line.
2. Note: If the Power LED stops blinking, the DT board may be defective.
3. Note: When the DT board is removed, the unit will power up with all functions disabled due to lack of data communication.
4. If the Power LED still blinks, it is possible that the problem is the PA or the DG board.
Shutdown Detect Circuits
What will normally cause the TV to shut down?
A short circuit on any of the voltage lines
An over-voltage condition
Abnormality in the Control Drive Pulse circuit (SC, SU, SD, and SS boards)
Cases When Missing Voltages Can Cause the TV to Shut Down
Missing the source voltage to the PA board (STB14V) from the P board
Missing output voltage from the PA board to the DG board.
Missing 15V or VSUS on either the SS or SC boards while the control drive pulses from the D board are being provided.
If the SUB 5V, SUB 9V or MAIN 3.3V is missing on the DG Board, the unit goes into shutdown.
The power LED blinks ten times.
The voltages are monitored on the DG board by the MPU, IC1103. 
Shutdown due to Over-voltage or Short Circuit
This could happen if there’s a short circuit in one of the B+ lines from
the PA board, an over-voltage condition, or missing STB 14V from the P board.
If any of the SUB or MAIN voltages that are highlighted on the DG Board is missing, the unit goes into shutdown.
The power LED blinks ten times.
If any of the voltages created on the PA Board is excessive or shorted, the unit goes into shutdown.
The power LED blinks ten times.
The base of Q5642 being low indicates a short circuit in the Main 1.8V, Main 9V, or Main 5V output of the PA board.
The base of Q5641 being low indicates a short circuit or an over-voltage condition in the NR14V, Main 1.8V, Main 3.3V, SUB
9V, SUB 3.3V or SUB 5V output of the PA board.
