Panasonic TC-P50GT30 screen washed out

[djw43]

I had 7 (not 10) blinks, and replaced the SD Buffer card, turned it on and the TV powered up!
But this is the new problem, below:
any chance for survival, i will search some...

Ve looks way too high... Are you sure it's that high? Can you adjust it to 120-140V range?

I'm confused with 10 blink SD card replacement. Never heard of a 10 blink being a buffer. Was the Sd shorted?

yes the SD had shorts on a few of those connectors to ribbons.
this GT30 was 7 blink, i also have a GT25 thread, sorry to be so confusing.

gonna check Ve again and see if it is adjustable.

You got an oscilloscope lying about?

Ok so if 7 blink you may have time to edit the first post from 10 to 7. I'll hop in the back seat and see what Tom unearths for you

Re: Panasonic TC-P50GT30 screen washed out

My bad I meant 7 for this device. I am working on three , a gt25 10 blinks, this gt30 originally 7 blink replaced the SD buffer and it powered on.
Third is the vt50 that we have resolved.
Sorry to be so scattered I really appreciate all your help tw

Re: Panasonic TC-P50GT30 screen washed out

i'm am getting somewhere, the set clicked off, 8 blinks, disconnected SS53 and tv powered up blk screen, then i shut it off, reconnected SS53, and found continuity at SS53 pin 1 and 2, also at ZA102-ZA105 and ZA102-ZA106 points to SS as you guys suspected.
I ordered one for $25, and I will be back....

Re: Panasonic TC-P50GT30 screen washed out

TPVE should be 165V on the 50"

Not sure on your test method.
Fault looks like SS board anyhow - I bet if you repeat test with new board, it'll do the same and read the same...

Re: Panasonic TC-P50GT30 screen washed out

I'm not entirely convinced SS is the issue, could still be on the SC side of things especially since the buffer was shorted, maybe Sc is wounded. I have a feeling we've seen something like this before, just can't remember what model to find it in a search

I'm almost on the fence with this one Tom, myself. I'll keep digging to see if I can find a similar problem

Re: Panasonic TC-P50GT30 screen washed out

last question on this TV this week, could the SS cause the blah screen?
