I can watch video on this TV, feeding in from my PC's HDMI port, for about 10 minutes. Then, the video cuts out. I can get it to come back by turning the TV off and then on again... but the video will only be watchable for about 30 to 40 seconds and disappear again. Power cycle again, and I get another 30 to 40 seconds. Is it the caps? I examined them and they looked okay. Should I replace them anyway?
Hi Curtis
You`ve mention Capacitor, are you referring with the TV or the PC?
Testimonial: "I was thinking about the caps in the TV's power supply. Upon re-examining the caps there, there is at least ONE that's puffed out and deformed."

If the tuner is bad, changing the mainboard should fix the problem.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.
You have a few choices:
1. If by chance the TV is still under warranty, go that route.
2. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
3. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

If you have a cable box, then you have to pick the right source. So on your TV remote you need to pick the source button and then scroll down to HDMI 2 as the source. HDMI 1 is the blueray device. HDMI 2 to watch TV

I was having the same issue. I found this on Fixya and it seems to have worked.
Okay I just called and found this out. I have the 32 inch vizio hd flat screen. My problem with weak and fluctuating volume, was that I have a cable box. Go into menu, then audio and under the advanced audio section you will see srs trusurround HD and srs trusurround. Basically this function automatically adjusts volume levels for satelites and whatnot. But because cable boxes automatically have this feature you could just turn off the srs trusurround. Hopefully that should help you.
