Re: TNPH0783 y placas compatibles



Sorry, I've just seen this.
Unfortunately, I haven't yet found exactly the part I need. Did you have the same problem?...

Re: TNPH0783 and compatible boards

Thanks.
Well, I've read in several places that this 'Audio PWM SOS' description for 14 blinks is not very 'accurate'. For example, HDMI circuit part errors that how to this blink code seem to be common (and I guess that's not exactly an 'Audio PWM error' would mean, but I could be wrong).

Re: TNPH0783 and compatible boards

Just for the record, I've found the manual for my exact TV model (but different chassis/connectors). It is attached....

Re: TNPH0783 and compatible boards

Thanks.

I have 'tried' to read that troubleshooting guide. I've also followed the Youtube video on 14 blinks error for Panasonics.
For the troubleshooting guide there's not really much info on the 14 blinks error: it says it's the A board or the P board. I can't get to force the situation where the LED stays red (which would be a P board problem) so I guess it's an A board problem.
Regarding the Youtube video that shows the steps to check for shorts, I can't seem to find any short apart from the pins that are supposed...

Re: TNPH0783 and compatible boards

Thanks. I am not sure what to measure.
I have tried measuring between F15V and GND pins in A7 connector with the device powered on and there is no short and there is 250mV only (?). Not sure what that means. (sorry, I am not electrician)
I tried to force the case mentioned in one "Technical and Troubleshooting guide" (not exactly the same device) to get the 'solid red' after the 'relay click' (which I couldn't really hear) and I always got the 14 blinks.
Could you tell me what can I check to be sure the A board is...

Hi guys,

This is my first post.
I have a Panasonic TC-P42X10L whose main board seems to be broken. It shows the 14 blinks error. I am not an expert on TV repair, there's probably no one in the country that can help and it is probably not worth spending a lot of time on replacing parts on the board because it's an old board (maybe I am wrong on this).

I want to buy a replacement for the board: TNPH0783 FL 2A main board.
The problem is that this is an old TV. There seem to be variations and similar boards and I don't know which one to buy. I haven't seen...
