5 blink code says missing/shorted P5V or shorted Vda line. Cannot find any evidence of a short. I get 5V momentarily on plugging into AC, before gets shut down by SOS. Anything else to check??

Re: Panasonic TC-P50G10 5 blinks
Any history on the set?
Remove the SC20 connector and powerconnector on the sc board. Meter in diode/beep mode and put the propes on the SC board connector , do you get a continuously beep?
Do the same on SS board.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

Re: Panasonic TC-P50G10 5 blinks
I removed SC20 and SC2 is the connector to the power board, and yes there is a short between the 2 pins on SC2 on the SC board. I assumed 5 blinks was something on the main board and this short would be a 7 blink problem.
So I have a short somewhere on the SC or SD/SU?
Isolated SD/SU boards, turns to 3 blinks.Last edited by kevinm34232; 08-15-2017, 08:27 PM.Comment

Re: Panasonic TC-P50G10 5 blinks
Also did the resistance test on SC/SD/SU, SD and SU tested OK, SC tested as follows:
"Using a digital meter measure the resistance between the VF-ground screw (Floating ground) and pin 3 of connector SC42.
Also measure the resistance between the VF-ground screw (Floating ground) and pin 5 of connector SC42 on the SC board.
The normal resistance for pin 3 is approximately 2.9Kilo-ohms and approx. 5.7Kilo-ohms for pin 5."
pin3=2.9k
pin5=5.3k
Is that 5.3k an issue from the normal 5.7k?
NM. Just checked SC board and just about every through hole transistor and diode shorted. I was thrown off by the 3 and 5 SOS codes.
Is this board worth repairing?Last edited by kevinm34232; 08-15-2017, 09:25 PM.Comment

Re: Panasonic TC-P50G10 5 blinks
Most of these models all have shorted sc boards.
It is worth to repair the board but dont buy a repair set , to much money. It is best to figure out which parts need to be replaced and usually it is not just a few fets.

Re: Panasonic TC-P50G10 5 blinks
I have a P50G11B,it is almost the same except for the A board layout is different,when i got it had so many problems.
Had to buy the SC,SS and SD boards,my SC had ALL of the transistors shorted and almost all of their drivers too,burned resistors,only 4 diodes were still working,a repair was possible but the FETs were more expensive than a used SC working where i live,and the drivers that failed i couldn't identify them,let alone find a replacement.
By reading on how your SC failed,maybe it is not worth it,sometimes the IGBTs will seem shorted,but it is only their drivers,which are some small SMD 5 pin near the transistor it controls.
Should be giving 7 blinks for a scan circuit fault,but maybe it is also shorting the voltage supplied from A board flat cable to SC.
I've repaired mine,excelent picture,no problems now except for the really bad black level.Last edited by Biruslapio; 08-16-2017, 07:29 AM.Comment

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Hi Folks
I'm looking for a extreme high current short killer solution for a reasonable cost.
I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
After taking off the socket, the shorts dissappear again.
The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...10-15-2024, 10:13 AM -
Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hello,
Stopped by this site trying to fix my parents Panasonic Plasma TV.
Model number is TH-50PZ85U
Power comes on and the red power light stays on solid.
Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.
I also hear a few clicks.
I also think my parents said there was a thunderstorm and the TV failed after that.
Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM
