This is how to fix a Deawoo DP-42SM Plasma

[jeffescortlx]

This model has a common problem with no-video. I've search the interweb high and low looking for the fix, and all I found were other people with the same problem, but no idea what was wrong.
It's what I call a first generation plasma, it's not a HD panel. No tuner, and no internal speaker. So it's not worth much, but the fix can be free if you have the right equipment.

The problem:
Powers on, audio works, on screen menu display work's, but no picture from any input.

The fix:
Chip number location IC 401 on the PCB Video SP-120 board. It is a SMD BGA chip, Philips SAA7118 video decoder.
All it needs is a reflow.

Hmm really? I happen to have 3 of these sets, ALL with the same exact problem, except the first one I got of I shorted out a transistor or a mosfet can't remember =/. I bought them all for about 40$ total. Now they are all just stored away still not working with boards and screws lost around the room. I'll try to dig it up and give the fix a try.

Just wondering how you happen to figure out this solution? Its an old plasma I know, but I still like the design of the set itself.

Good find, I like to read stories where someone went out of their way to fix and ongoing issue.

I just reread the fix and seems the problem I have is different. The TV doesn't turn on, the relay will click and the red LED will turn green, however the TV is still on, (no backlight on)
