If the sound is working, I doubt the power supply is at fault. You can check with a simple voltmeter - red is positive, black negative - there should be 24VDC. There is an on-board regulator to drop the voltage for the CPU, etc, . THere is a green LED on the main board, so even if you don't have a Voltmeter, there is a visual indication that the power supply is somewhat functional.

I found a poor connection from the 24V power supply over to the inverter boards. I re-crimped the IDC connectors to the 24V supply and all was happy-town.

It really doesn't have a reset for the picture. I would be looking at the inverter and power supply. If it is four years old most likely it is the inverter. The inverter is on the left side looking at it from the back. Have a repair shop check it out for you. Thanks

Proview rx 326 model 3200 tv sound but no picture


I just fixed my proview 3200 that doesn't have picture but with sound.
First, thanks for the tips I got from this forum. I checked the 24v from the power supply board and that's perfectly working fine. I then check the fuses in the Inverter board. There are 4 white fuses (2amp I guess, i cant remember) and 1 black fuse (1amp/76v just behind the wire connector going to the power supply board). The black fuse is the one that blown out on my tv. This fuse supplies power to the LM358A IC. I know its not right but I just solder a thin piece of wire to short circuit this fuse. I'm lazy to drive to RadioShack to find this fuse. :)
....and that worked beautifully. Check the picture attached for what I did.
