What type Flat Panel TV is this? LCD? Plasma? Rear projection? This information would go a long way towards determining the probable cause.

However, a first diagnosis is that there is apparently a circuit overheating.

I've found that on some of the lower cost brands, the manufacturer does not test them well enough to cover all climates, or long enough to determine weak circuit design flaws. Unfortunately, it usually means a trip to the repair shop, which these days can be a high percentage of the replacement TV cost.

If you are willing to try, and can be CAREFUL, you can open it, clean out any accumulated dust/dirt (which can exacerbate overheating), possibly check (unplug/replug/wiggle) all connections between boards/modules. This may clean a dirty contact if it's gotten a tiny bit corroded or dirty (usually on older sets, or high humidity or high smoke environments)

WARNING - the power supply in any TV set will retain dangerous voltages even after unplugging. I'd recommend to unplug it, wait no less than 24 hours before delving inside it.

Never attempt to supply AC power to a set that has the back cover off... lethal voltages ARE present during operation, yes even in LCD TV's.

After about 30-60 minutes TV starts to hum and picture gets distorted, could this be the color wheel...???


Sounds like a sync problem due to color wheel speed. clean and lubricate color wheel motor with tiny amount of Z-Max lubricant (liquid Buckey balls, available at Wal-Mart), on each bearing. make sure wheel is free-wheeling and turns easily. Should cure problem. If the color wheel is in good shape, there is a power supply problem, which may be due to dried out electrolytic capacitors or a regulator that's failing. Troubleshooting or controller board replacement may be needed. Regards.

Distorted color on hdmi output


If you haven't already stumbled across the fix: I just had the exact same problem after about eights months of casual use. Unplugging the DVD player for about 15 minutes and then plugging it back in "solved" the problem. Until next time it happens, anyway.
