Question about Vizio L32 32 in. LCD HDTV
Its not that big of a deal, but on my Vizio vp322, I have my pc connected in the rgb slot, xbox in component, dvd in svideo, ect ect......
What I do mostly is play mmorps on my pc, and I notice the screen will be bright and like I have it set, and like clockwork the screen will dim a good bit, not so bad that I cant play game, but I wonder if that is just how vizio rgb slots do for everyone. Or just me. I dont notice it on tv, or dvd , just pc. Does anyone elses vp322 do that?

Probably the power supply has gone bad.. This happens with no warning. Sometimes it is just bad capacitors that have leaked or puffed up in the power board and a good tech can do a cheap fix by replacing them.. Other wise the PS board has to be replaced

I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

Remove the 4 screws holding the stand. Remove all the perimeter screws. Remove all the screws from the bottom speaker panel and the rest of the perimeter screws and the ground wire screws at each speaker. remove the screws on the surface of the back panel and you are in. The power supply is the large board in the middle. The bad capacitors are in the secondary and were C233, C234, and C236. I replaced these 3 capacitors and fixed this problem.

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where.
