Philips 55PUS6754 with lines after few seconds
Hi,
I have tried to replace TCON but it didn't help.
The strange is that it shows Philips logo before the lines. Tried to cover some of the lines with tape on the ribbons to the screen but had no success.
screen: tpt550u2-eqya3.g
tcon: 6870C-0769A
I will appreciate any help
Many thanks

Re: Panasonic TX-P50VT50E completely dead!
If lines were vertical it means more then likely your main av card died.
It's very hard to find item.

LCD screen swap between UE65JS9500 and UE65JS9000
I got UE65JS9500 with cracked screen and I wonder whether it would be possible to use LCD panel from UE65JS9000.
I know that one connect box works for both models, TCON and control board from the TV looks the same so I'm pretty sure it will work.
I would be very grateful if anyone with more experience would give more information about it.
Many thanks

Slight backlight problem after replacing main AV card on LG 65UB680
Hi,
I was struggling to find replacement of the main AV card for 65" LED LG TV 65UB680 and finally I have purchased main board for 79" model 79UB680.
Board does fit and works except slight problem with backilight at startup where two bit darker bands are visible. As soon as picture is displayed fault is not visible. I believe that such fault is caused by different firmware design for bigger screen.
Could you let me know how to access service menu on that model to change screen size?
I have tried common metods like "Press and hold <OK>...Last edited by marekk; 06-23-2021, 08:55 AM.

Re: Panasonic TX-P50UT30B 6 blink error
only those ( PC685, PC581 and IC921) came from faulty SN board like TNPA5330 or TNPA5457 with faulty buffer chips which I have used as source of parts.

Panasonic TX-P50UT30B 6 blink error
I'm struggling to fix Panasonic plasma TX-P50UT30B.
TV doesn;' turn on and LED blinks 6 times.
Faulty is SC board like usually it this case it's TNPA5351 AF
I have changed already Q622, Q623, Q600 and Q661 which all were shorted.
After that TV still doesn't turn on showing 6 blinks, no shorts fortunately after powering up.
Later I swapped from my other death boards PC685, PC581 and IC921 but it didn't change situation unfortunately. Both buffers I swapped from my TX-P50ST30B.
I have found no other shorts.
I will appreciate any help to solve...

Re: Panasonic TX-P50GT30B screen problems
Ok, blue sparkles I have solved partialy by dropping the VSUS to 209V, I hope it's not too low, stil this part of the screen is sligtly brighter than rest.

Panasonic TX-P50GT30B screen problems
Hi,
After repair of the SC board I noticed very thin part of the screen at the top which shows blue sparkles. the area where this sparkles does appear is around 10 pixel lines tick and runs through most of the screen length. On top of that there is quite significant screen burn on the right side of the screen.
Is that repairable?
I would really appreciate any advice with this problem.
Best regards
Mark...

Re: Panasonic TX-P42S10B 14 blink error ?
More than likely you got broken HDMI chip an the main AV board AD740 or similar.
