Re: Panasonic th-p42x10z

so it is the panel thats buggered then?

Re: Panasonic th-p42x10z

Been heree before. Clip sos6 from SS output to bottom panel driver boards. It's an erroneous error. Panasonic's are very temperamental with vertical VA buffer shorts.

Re: Panasonic th-p42x10z

well this tv went for about 5 mins with the 2 lines on the screen and not sure what i did if i just unplugged the wrong cable or something but when i turned it back on i was back to the same 6 blinks that i had with the other tv so after 9 months of this tv sitting in the spare room in bits i think i ready to give up. I think i will take the boards out and try to sell them since i believe its the panels that are the problem...lesson learnt dont play with plasmas lol
Anyone interested in the boards?

Re: Panasonic th-p42x10z

Well I gave up on my original tv for a while but i have just managed to get hold of a second tv of same model..This one had the 12 flashes of led when powered on so changed my A board over and to my surprise it goes lol just not 100% the screen has 2 little vertical lines one each side of panel so now i hope its one of the spare boards i have and not the panel itself...

Re: Panasonic th-p42x10z

yes really appreciated all the advice and feedback you gave us tw2005,at least we fixed one problem.
Now this maybe a silly question but was just reading on another forum about a panasonic plasma with 6 blinks when plugged into an extension cord but turning on when plugged straight into the wall socket... now do you really think this would make a difference because i just realised everytime i plugged my tv in it was plugged into an extension cord and i never tried it into just the plug. hmmm not really hopeful but i guess it could be possible..

sounds crazy, you'd have to wonder how many amps it was drawing.

No I think short of finding a working TV and swapping your boards one by one into it to replicate the fault, I have no ideas at all.

Re: Panasonic th-p42x10z

tw2005, we appreciate the help and the time that you give. Who would think that it wouldn't show an error with that drop in voltage. My thoughts without investigating are that either the Power board is saying all is fine or that this error isn't being checked for after the display is turned on. Probably the first is most likely and is part of the board fault that it thinks it's in regulation with load when it's not.
Nick hasn't given up on his yet, he is just busy with other things at the moment. Kind regards

Re: Panasonic th-p42x10z

Wow. Sorry I couldn't nail the fault for you.

Re: Panasonic th-p42x10z

Nick has very kindly let me try his power supply pcba and I'm pleased to confirm that the picture is now completely normal. Vsus and Vda are stable under load unlike my pcba where they seemed to sag. So am now confident that this was causing the picture issues.
Unfortunately this doesn't help Nick with his set though.
Kind regards

Re: Panasonic th-p42x10z

Re: Panasonic th-p42x10z

Re: Panasonic th-p42x10z

Re: Panasonic th-p42x10z

Well that is a bugger the thing is with every board change i have had the same result 6 blinks i also still got the 8 blinks when unplugging the sc20 cable with the new c boards.I didnt see anything obvious on the ribbon cables to the c boards. I dont actually know when the 6 blinks happened but i believe the tv was working one night and the next time turned on had 6 blinks.

Yeah, well if that happened to one of mine I'd be thinking SC. You virtually need to find someone with a know working TV and put your boards in one at a time for testing.

ignore wrong thread sorry.

Re: Panasonic th-p42x10z

Well i was starting to wonder about the power supply myself. If the power cord is plugged in but tv not turned on should i have a standby voltage somewhere?
When you push the power button on the tv the relay clicks and few seconds clicks again which is when it starts the led flashing.
I did try a different A board before the c boards arrived and i got random flash codes like 12 or 13 cant remember exactly. So With my test results you said the tp sos6 was high on the sc board the question is what can i test on the power board to narrow it down or is it another replacement board.. that would leave me with the two button boards and speakers i believe lol other than the screen.

I doubt it's power board, you already measure Vsus matching the sticker

Re: Panasonic th-p42x10z

Ok after waiting nearly a month for my c1 and c2 boards to turn up,they finally turned up today and i installed them and.... what do you know I have the same 6 blinks i have had all along So now i have replaced the SS,SU,SD,SC,C1,C2 boards and i have also tried a different A board...all with the same result. Please dont tell me its the screen stuffed..
I guess the question is what can i do from here I really didn't want to fail on this.
Any more suggestions anyone would be appreciated.
thanks
Nick

pretty much everything except the power board. I'm out of ideas. If all those board were good that could only leave bad connections on the cables or ribbons but I've already mentioned that before.

can't see it being screen as I'd expect 7 blinks and damaged buffers not a 6 blink.
