One of my 2049s has gone all yellow again. I originally cannibalized a 2082 transistor from a 9400 chassis I brutally murdered (long story) to replace the blown C3502-E. If you check the spec sheets, their specs don't quite match up -- specifically, the 2082 is rated for only 170v, the 3502 rated for 190. So imagine my surprise when I pull out the neckboard, look at the schematic, and realize the 2082 is on the still-functioning red channel! I expected it to be toast by now, but another one of the original transistors beat it to the punch, apparently. I wonder if I'll have to replace all the 3502s eventually...

Anyway, I'm curious. Since nobody sells the C3502 anymore, what are you guys using in your 9200s?

Brightness issues with these are typically caused by corrupted memory from the on-screen menu. Hold the DOWN and SEL buttons on the remote at the same time. This will access the Factory Menu. Then do a memory reset by choosing RE (recall). After that, your brightness should adjust up just fine.

If not, then go with the caps. I have a list posted on here in another thread if you need it...
