100% sure

Re: Panasonic TX-37LX85P blink 3 times

Hmm. What is the voltage across the large "33" capacitor next to that transistor?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

it's 0V, just to be sure i removed the wire from pin #5, #6 and resistor on #15 and #1.

Re: Panasonic TX-37LX85P blink 3 times

But you were getting 0V before, so what has changed? Can you put the transistor back on?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

I did, and back to 3 blink

[tom66]

Re: Panasonic TX-37LX85P blink 3 times

And does the voltage now differ from 0V?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

i check capacitor now and it's a 0V

Re: Panasonic TX-37LX85P blink 3 times

Is there any way to bypass the 3 blink check, i think something is blocking power.

Re: Panasonic TX-37LX85P blink 3 times

Panasonic manual doesn't specify exactly whether AG_SOS is the 3 blink code or not. I think it might be picking up a brief spike on it but I'm not sure.

I found somewhere that mentioned 4 blinks as being a SUB12V problem and 3 blinks as simply "SOS". Perhaps it is corrupted firmware or processor problem. I am way out of my depth here. :/

Re: Panasonic TX-37LX85P blink 3 times

ok, thank you for trying. I am thinking to replace a whole A board, if i found one.

Re: Panasonic TX-37LX85P blink 3 times

Ok i order A board from ebay, hope TV will work now. :-) thanks tom66 for your time

Re: Panasonic TX-37LX85P blink 3 times

Hi, i recived A-board and connect it. When i start the TV it is fast blinking green LED, and i hear clicking from the inverton board. (i think) click sound repeat every 5-6 sec

Re: Panasonic TX-37LX85P blink 3 times

In a dark room is TV screen lit?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

it is continuously blinking green (i think the TV cannot start because the invertor dod not pass check), when i try tu unplug invertor i got picture 'NO SIGNAL' and there is 1x red LED blink everi 3-4 sec.

Re: Panasonic TX-37LX85P blink 3 times

Green blinking isn't an error code. Try with the TV button board unplugged & use remote to turn on. Unplugging the inverter and seeing a picture makes no sense -- it's responsible for lighting the screen.

Re: Panasonic TX-37LX85P blink 3 times

No my mistake, when i unplug the invertor and i use flashlight i can see NO SIGNAL for a few seconda and then TV turn Off with 1x red blink. But when i pluged invertor the tv cannot start it is always blinking green, and then click and again blinking green and click and again blinking green etc etc

Re: Panasonic TX-37LX85P blink 3 times

Is there an ERROR signal from the inverter board?
How much does 24V measure on inverter?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

i have 24V on invertor board (mesuring on fuse)

[tom66]

Re: Panasonic TX-37LX85P blink 3 times

What about the error signal?

[rtstorm]

Re: Panasonic TX-37LX85P blink 3 times

What do you mean by error code, sorry i dont understud
