When i turn my Toshiba 26av502r on the volume is high? i tried unplugging and plugging it back to reset the tv but that doesn't work. i went through the setting and everything appears to be fine. Any Suggestions?

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

I'v Toshiba and they have to replace the controler board and video board.

It is an hardware problem

Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.

hi the best thing to do is call toshiba and let them know your problem

I had the same problem, you'll probably find that that particular button will push further into the set then the others, this is due to the a weakening of a cheesy metal guide which directs the projection off the back of the button into the corresponding microswitch. This metal guide will bend and will push against the switch.My solution, (and it ain't pretty) was to unplug the set, remove the button( I used a dremel cutting bit), locate the guide,a small metal plate with a hole in it. Bend the plate toward the front of the set then tape over the hole. I haven't had the problem since.You WILL have to use your remote for further functionality of the volume, However all of the buttons seem to be inherantly poorly designed and will weaken over time, AVOID USING THEM!
