Im hacking the Zenith 5" lcd for the digital photo frame project. My screen went dead. I've been trying to get it to work again, and thought that maybe my connections were bad so i was redoing them.

Then i noticed that my yellow power pin was getting really hot, then the wall adapter started ...

i think it might have been my wall charger for the screen....

unfortunately, now the sandisk card reader isnt powering up.

so this sucks.

maybe ill try and get another power supply...

ive noticed that playing with the screen brightness makes a big difference. On all the way dark-----theres no lines and no rolling bars (but the picture looks like a negative image)

and on full bright mode. Theres two 1/2 inch black (negative like) bars that roll upwards, but in between the bars ...

should i ground the video wire as well?

my old one did that. the problem was that the power supply wasn't regulated enough and had too much noise or something. are you running it on batteries or the wall adapter? if you're using the wall adapter, try batteries.

are you referring to the OP or my picture?

Im running off of wall adapter ...

okay, so i replaced the video wire with thicker wire and that didnt do anything.

Then, some loose wire touched a part of my board and a big spark happened, and now its better, but not right.

The bars are smaller and more of the picture shows through, but there are still two 1 inch bars that roll ...

hey there im doing this same thing and am getting lines and bars across the screen that roll, any ideas on what it could be? ive resodered almost everything thinking maybe a bad connection?

thanks

i have a similiar problem----pic attached. the bars roll up the screen, the color is perfect in between the bars, but...
