Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

Hello,
There is a software update that is available for some Mitsubishi dlp models. The wd-65c9 is one of them. When I experienced your problem, I went to the website, downloaded the update, and installed it on my tv and boom, its fixed. It's super easy, free, and takes a few minutes.

Power off presents magic focus screen, tv must be unplugged.


you will have to determine if tv fault or cable fault, shut down cable box and unplug it`s power cable. Once all power is removed from cable co. equipment retry your tv controls, if tv turns on correctly problem with cable co, if not tv has corrupted data (try unplugging tv for 1 minute and then retry) ifstill bad tv has bad control board or logic problem, either one will require tv tech to fix, hope this helps, video-tek

Tv stuck on ''sale'' screen


Normaly you WILL have to obtain the remote to get the tv out of sales mode.

A few tricks that you can try.
1. Hold down the menu button as you power on the tv.
2. Hold down the channel up and down (at the same time) as you power on the tv.
3. Hold down the volume up and down (at the same time) as you power on the tv.

Sometimes you have to hold the buttons down for up to 10 seconds after the television is powered on.

Lastly you can try unplugging the television for an extended period of time and see if the television will reset itself.

If you have no luck with these tricks then you are going to have to post some information reguarding the manufacture, model # of the set so someone can look up the information for you.

Projection TV keeps shutting down


Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

My Sanyo HT28745 28" HDTV clicks but doesn't turn on


I have had a similar problem with my tv, it has something to do with the power supply.Try unplugging your tv from the AC outlet. While unplugged from the power supply hold down the - volume control and then plug the tv back in while holding down the - volume control. It should bring up the service screen. If the screen turns on and is blank then it may need to be brought in for repairs.

If the screen does turn on, either blank or with the service menu, turn off the tv and unplug it from the power supply again. With it still unplugged hold down the power button on the tv and then replug in the tv. continue to hold down the power button until the tv displays a video signal on screen.
