Hello, I have one of these tvs and it works great. My problem is that my screen is cracked and cannot find a replacement. Do you want to do a swap, either for your screen or you can purchase my working tv, and replace with your screen? Just a thought. LRoller

If it is under warranty, you would be better off the return it for an exchange as the main board will need to be replaced. this board is not cheap. Good Luck

This sounds like a signal tuner (audio/video inputs), or the main board if inputs are on it! It is also plausible to be a bad cap (Capacitors) that are bulging on top and or leaky (brownish stain) causing a harmonic within the power feed to the audio!

My protron pltv-4250 won't turn on. it was working fine and then it just wouldn't turn on. I unplugged it and waited for a while and tried again, but no luck. any ideas?

The power supply boards are known for having swelled capacitors and may not allow the set to start up.......these can be replaced by an experienced tech reasonable cost. If the entire board needs replacement,they are difficult to find........just to be sure the master power switch is on located near the power receptacle too!!
