Re: Sony XBR-43x800e TV had sudden loss of picture

I went ahead and desoldered one of the capacitors that read 0.8 ohms. (It measured around 2x1x1 mm, but many on the board were even smaller.) It turned out that was the bad one, as after it was desoldered, there was no longer evidence of “shorts” on the other capacitors. The picture is back on and looks fine! While I have had some experience repairing electronic devices, this was definitely challenging. I appreciate the information on the posts.

Thanks, alfatv.
After reading your post, I went back and re-measured resistance across the capacitors with my multimeter, which has a resolution of only tenths of ohms. It's difficult to make sure one has good contact with these tiny capacitors, so there may be some residual resistance with the probe contacts. However, I did notice that there was a progression of resistance across the “shorted” capacitors from one end of the board (1.2 ohms) to the other end (0.8 ohms on 2 capacitors). So maybe it's one of the 0.8 ohm...

Sony XBR-43x800e TV had sudden loss of picture. Screen is dark except for backlight. Sound is present. Main and T-con boards have been replaced (T-con twice from sets with reportedly cracked screens) with no improvement. When one side of the cable between T-con board and display panel is disconnected (call it the “bad” side), the corresponding half of the panel is white and the other half black. When the other cable from the T-con board to the panel is disconnected (with the “bad” side cable reconnected), the whole screen remains black except for the backlight. I've tried blocking several...
