Re: panasonic TH-42PC77U plasma television half screen problem

Hello r_j
I attached a picture.
Hopefully i am testing correctly?
I held the right probe stationary and moved the left probe down all brown connectors.
I got a reading of. 7
One other note.
You can't read the word panasonic in the top two ICs like you can on the rest.
Does that matter?

Re: panasonic TH-42PC77U plasma television half screen problem

Hello
I have tested the lower board.
I get a reading of .6 or .7 on the analog multi meter.
I have not tested the upper board.
I figured if the problem is the lower part of the screen, would be associated with the lower board?
What would you suggest to do next?
Upper board or something else?
Thank you!

Hello R_J...yep....the picture you attached is the same board. thank you for the attachment instructions by the way....
as far as the pins that attach to the Y-SUS board..there are many and they seem to go to different parts of the board....can you tell me which pin or pins do I need to use?
thank you

hello nomoresonys....I need to try the test again...thank you for the feedback also..

Hello!
I removed the lower board...it is a little different than the one in the video. I am not sure how to add a picture to the post...
I have an analog multimeter...had an inexpensive digital one..not sure where it is...i set the meter to continuity. when i attach to certain pins on the main connector to the power control the board? and run the alternate wire across the 4 different IC's, it registers 1/2 continuity or beeps.
I did notice that 2 of the 6 IC's don't seem to have the panasonic writing...

hello,
I hope someone on this forum can assist me.
I have a panasonic TH-42PC77U plasma television.
the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
I have read some posts that suggest the problem is related to the boards on the left...
