Proscan PS34190 Problem
I have a Proscan PS34190 with chassis CTC172ATA that has
developed a problem: when I press the ON button, it takes two, three, four or more hours for it to turn on! I took the back off, and I can see the fan twitching, and hear something cycling - it is as if it is trying to turn on, but just hasn't enough oomph (hope I'm not getting too technical). I tried changing U4100 (TEA2261), but no change. Any suggestions? Note: I am not a technician, but I am a good solderer, and can follow directions. Also, I have a schematic. OR - does someone have a parts unit out of which they could sell the module with the fan on top? Maybe if I change that whole module I'll get lucky. Here is a picture of said module: http://www.markbuckles.com/misc/proscan.jpg Thanks!
