3 tvs 3 different issues 1 thread

[christo]

I've been lurking for the passed two weeks and have now registered to try and get some assistance so I can get some sleep!

Problem tv # 1: 32 inch samsung lcd
The samsung tv has no picture just a 1 inch strip at the bottom of the screen, everything else is white horizontal lines with black background.
It has sound and turns on easily.
I've reseated all cables and ribbons with no luck.
After multiple tests I've decided must be a bad panel but I decided to ask everyone else's opinion.

Problem tv # 2 RCA led flat screen
Only turns on after multiple tries of unplugging and plugging in.
I've switched a few caps and a cold soldering joint to no luck the issue remains, I will be switching all caps on psu to see if this works tomorr only tried a few so far.
If I turn the tv off I have to redo the unplugging process to get it to power on.

Problem tv 3 : Philips 40 inch lcd turns on, back light is in on, no picture or sound, I replaced two caps that kinda looked funny and to no avail that didn't work so I reseated the cables and It did nothing. There is a clicking noise when plugged in. Also has no standby light just a white power light whenthe tv turns on

Models and pics of all board will be posted tomorrow, I decided to post thread tonight to get a head a little.

read the stickie posts, try to post some good clear pics., of all the individual boards and pics. of how they are all connected, a pic. is worth a thousand words, it might get pretty confusing only having one thread for 3 tvs.

I agree - it will be horrendous 3 separate threads required.
I was going to try and justify that but I dont think there is any need.
Header for each thread should include make model no and brief description
of problem. In each thread if you are changing or have changed caps tell us what you used- for a power supply they should be low esr known good make from a known good source
