If you have a USB cable from a digital camera, plug it into the service port on the side of the tv/monitor and plug it into the computer and it will come on. It is some sort of short in the on/off circuitry and this gives it the boost it needs to come on. I received a free 23" Olevia TV/Monitor because the guy was having the same problem and didnt want to try to fix it. Very easy fix if you have a digital camera USB cable.
I have the same problem with my 42 inch plasma panasonic television from COSTCO. The red power light blinks, but does not turn on. By unplugging and re-plugging the power cord from the wall, it restarts.
On December 19, 2007,I had the same problem on my 42" plasma,. he light blinked twice and there was no picture. My tv was just six months old and lucklily it was still under warranty. To my surprise, a panasonic technician came out the next day, literally 17 hours after I made the initial call. Turns out its a fairly common problem and relates to the failure of a circuit board. Had I been out of warranty, the cost would have been over $500, or just under 50% of the purchase price. While I am very disappointed by such a severe problem so early in the TV's life, can't say enough good things about their service. I had a whirlpool dishwasher fail over the summer and it took two weeks to get a service appointment and another 6 to fix it properly.

Hi there, 5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing. Hope this helps TV_Doctors

It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
