About three months ago my 3y/o daughter poured windex on the screen of my Toshiba 35a44 tv. I let it sit for a couple of days and removed the back half to let it dry. Plugged it back in and it worked fine. Now the demo mode suddenly turns on when i hit the chanel and volume buttons and most of the time by itself. Any ideas on how to fix this?

Hi, Since I do not have your tv model number so can't be specific, check Demo mode option in Menu and turn it off. Some tvs have selection like Store/ Display and Home mode, store or display mode is demo mode so set tv on home mode to turn off demo mode. Let me know model number of your tv if you have additional question. Thanks.
I had the same problem. Was told to unplug the set for 1 minute but it still was stuck in menu screen scrolling. So I was told to unplug the TV for 4 hours, it resets it I guess because it worked! Try it!
I contacted Toshiba and they said to turn unplug the TV for at least a minute, if that didn't reset it, then they gave me a service to contact. So I unplugged the TV when I was going to be gone all day, and tried it when I got home, no change at all. I had a repairman come by and he said the problem were the buttons on the TV that had to be replaced. He quoted me $240/labor and $5 for each button to replace (7), considering I only paid about $500 for the TV in December of 2004, I decided to just get a new tv with a warranty. I ended up getting the LG LCD Tv.
for this brightness problem actually came out from flyback transformer...so, before you spend and waste your money, try to adjust at back of your tv first. But if you aren't an expert, better ask technician to do because that transformer supply a very high voltage....there's two adjustment point at flyback transformer, one point for focus and the other one for brightness! try first...
