Re: panasonic viera red half screen

That is nonsense - no way an A board can kill the D.

Re: panasonic viera red half screen

spoke to my parts supplier and they are suggesting the a board could be killing the d boards

and trying to find ldvs cable for that unit is like trying to find rocking horses teeth

[tom66]

Re: panasonic viera red half screen

Well what else can it be? The LVDS cable could be dodgy, which is the cause almost all of the time.

Re: panasonic viera red half screen

Hi me again that screen has all went red again now can it be the control board again

[tom66]

Re: panasonic viera red half screen

Thanks for feedback.

[wreksta]

Re: panasonic viera red half screen

all fixed now mate new d board fixed it
thanks for all the help

[wreksta]

Re: panasonic viera red half screen

well they sending me another d board lets hope eh

[wreksta]

Re: panasonic viera red half screen

it still has the blinking led I think board duff going to get in touch with emostv

plus connector was lifted off the board not fixed by ground points

[tom66]

Re: panasonic viera red half screen

Uh, you got me. No blinks? The TV -was- working before you did the swap? You've possibly forgotten to plug something in or damaged something due to ESD (electrostatic discharge)?

Re: panasonic viera red half screen

right new tcon/ldvs came and now tv wont turn on with either the old or the new board in place

[tom66]

Re: panasonic viera red half screen

I though 1 blink was usually A board, but I've never heard of it on these sets.

Re: panasonic viera red half screen

it does it everytime tv will stay on 1 minute or more then flashing starts it gets faster then the clicking starts with it then shuts down flashing 1 red light checked the service report from you and I done procedure disconnected this n that and it final outcome was replace d board

[wreksta]

Re: panasonic viera red half screen

powering off is normal tom its error 1 even when it shuts down 1 flash according to the service manual and it confirms d board failure

[tom66]

Re: panasonic viera red half screen

How long does it normally last?

[wreksta]

Re: panasonic viera red half screen

yeah the powering off happens after I get a normal screen then red flashes then gets faster then the clicking then powers down

[tom66]

Re: panasonic viera red half screen

You've gotta match the suffix stamped in the yellow box after TNPA.....
I do not know about the powering off. Check all power connectors seated, power must be off while doing so.

Re: panasonic viera red half screen

now last clarification since looking at the set today I cant guarantee it has ever stayed on mate so have a fiddle with the ldvs then if no go order a replacement d board/tcon/ldvs board

[tom66]

Re: panasonic viera red half screen

Well I think the original fault was LVDS if that's any consolation but a D board fault has now appeared. Perhaps both were present and first was hard to see.

Re: panasonic viera red half screen
