Vizio Plasma 50HDTV10a problem

Re: Vizio Plasma 50HDTV10a problem

So I put in a new buffer board and used ysus. The lines in the middle are gone now but I hear a clicking coming from the ysus and the screen kinda flashes on and off with the clicking.

Any ideas?

Sounds like a buffer is still failed. Have you tried removing one?

I've unplugged both buffers but the clicking remains. The top IPM chip on the "used" Y-Sus board does not warm up like the other one. It sounds like the clicking is coming from that chip also.

And I'm guessing the clicking goes if you unplug the Y-sus?

How long between each click?

Check for stray dust or solder... I found an LG Plasma at the local tip which was not working but I cleaned all the dust out and what do you know it starts working again . I think it was cigarette dust because it smelt awful.

The clicking is fairly frequent, about once or twice a second. I'll try to clean it...

Ok. I purchased a brand new Ysus board today and installed it. The screen works but I get no picture, menu, or volume bar displayed on the screen. Is this caused by a main board?

Most likely you forgot to connect something. I am guessing you mean the screen glows but you get no image data. Check the Va power connector for the X buffer is plugged in - this is the little cable going from either Y-sus to X board or Z-sus to X board (sometimes both.) Also, check that the data cable going to the Y-sus is properly seated. And the LVDS connector - from the main board to the control board - check that.

Do you get sound, at all?

You were right, I didn't have the LVDS connector seated all the way on the main board!
I just need a top Y-buffer now


Thanks!

So is it fixed? I have the same tv, no pic just sound, with the clicking coming from the ysus board. How do you know you need a y buffer? I was hoping to fix by only replacing the ysus.

Thanks,
