Re: Panasonic TH-32A315M, standby red light, but won't power on
What is your PS_on voltage when you press power button?I assume no responsibility for any stupid suggestions I might post. -

I understand that this Chinese Panasonic is assembled on the TLC platform and assembled on the TP.MS18VG.PB77 motherboard.

If so, can you read the firmware (DUMP) from it as a programmer and post it here?Attached FilesLast edited by lotas; 10-13-2022, 09:44 AM.Comment

Hi everyone,
I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.
The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.
After checking the basics I did the following:- I measured all voltages and as expected the only active supply is the 3.5V standby. It

Hey All,
I have a Sony 65x900f that I purchased cheap because of a no-power issue.
I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.
I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate... -
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 -
No standby red light, nothing
This Sony has a separate AC->DC power adapter supplying 19.5V to the TV power board (JK3)
Disconnected JK3 power board from main board, checked voltages on all the pin outs
At a few pins I can see the power supply providing 19.5V to the main board
Based on the service manual triage.. it seems to be pointing towards the power board (JK3) being the most possible culprit
LED light turns on when I disconnect LED driver board ribbon from mainboard (so i thought it is the mainboard,... -

Consumption : when charger plg in = 0.004 amp
Only 3/5 vl are present when charger connected..when i put my red probe at the coils of 3/5volts and power on with my power suplly it try to rise than 0v.
when try to power on using power button i note this starnge value : 3v then 0.300v then 3v !
No light at power button led
All coils resistances :
Pl 2001 =3v measured with kohm.
pl 2004 = 5v measured with kohm
pl 6001 = 49.7ohm
pl 4012 = vccsa = 24.4 ohm
