Tv will not turn on the light on the front just flashes. It worked fine in the morning came home from work and can't get it to work. I unplugged it figuring it would reset.

Red flashing light on tv. Power went out

Flashing is either an error code or the set trying to boot up--some of the Mitsubishi sets if power removed will blink for a minute and then stop--then the set can be turned on.

a model number?

Tv projection Lamp might be some how the causes again.Tries unplug,replug tv back like about an hour later.Try it again,should work now.If not,yes the projection lamp,might have been kill by the cold weather.

I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did;
- unplug the wireless receiver
- unplug the main unit
- remove the digital transceiver unit from its slot in the back of the main unit
- plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers)
- unplug the main unit again
- reinsert the digital transceiver
- plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing)
- then plug the wireless receiver back in again
...presto the link is made, the 'W' stops flashing and the rear speakers work again.

Hope this elaborate reboot works as well for you as it did for me.

This is common problem of the failure of power supply board inside TV. You need technician to figure out this problem.

Your powerboard is damaged, and need to be replaced.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

• check to see if tv has sound when you turn on, then check menu for color, check if tv might be on timer. this might help!!!

your tv has hardware problem and Sony service person can fix it.

First thing i would do would be to check convergance amp ics

I had the same problem. Unplugged it, reset it, everything. I went to work the next morning and left the light blinking, came home from work and it was off. I turned it on and so far, so good. Just give it some time to reset internally
