I hope, and be thankfull if you can reply.

My problem regards my Haier 42" plasma - the panel and also the Y-sus, Z-sus...are LG PDP42V7. the screen turn to red from time to time, sometimes it's stays for a while, in other cases it's blinking red. it happens in all the inputs, if their is a picture you will see many red dots, but actually the all screen turns red (see it when no siganl).
Is it a prblen in one of the cards?
Tested all voltages, seems O.K...

Thanks in advance.

Tom.

i think it`s could be LVDS cable between main and logic board
take it off and clean plug back and put hot plastic from glue gun

Hi mulja, thanks for replying. when I discconnect the lvds from the main board.I get black screen. when returning the red screen is back.
The question is the red picture comes from the main board or from the control board..Ysus...Zsus?
Is there a way to bypass the mainboard and to see if picture is clean from there, by simulating t to the control board?

Thank again.

mulja:
Upload picture of your fault

but i think then you disconect lvds cable and get clear black screen whit out any red spots
then zsus and ysus seem to be ok

Check for rubber blocks under control board, if it has them, chuck em.
