Mitsubishi 45" Projection TV

Go into the 'Menu' -> then 'Setup' -> then 'A/V Connections'.

You should see an option called 'Locked to Input' switch it to 'No' and your problem should be solved!

Hi,check if power supply didn't get damaged, that's normally what gets damaged when there's a power outage.Sometimes it's just some capacitors that get damaged of the power supply.Have a bless one!

Did you ever get this problem solved. I am having the exact same problem?

I can help you unlock your Mitsubishi HDTV VChip.

Please follow these steps to bypass the vchip or reset the V Chip password.

I hope that helps.

Unplug it for 30 minutes. Then try again.

Let me know and I'll check the service manual. I've got a 65511.

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.

In your case I've seen this and it was a electrical issue between the DLP fan and board. The tv could have a problem with the digital tuner and not kicking a code due to low voltage ... it isn't expensive to fix, just hard to diagnose.

Do you smoke? The fans suck in smoke and it gets tar build up on the connections and that causes this in some cases too.

First do the self diagnosis test to see what area is effected, search threads here or goto www.ctechnicians.com

Try Re-soldering the vertical yoke connections and vertical output IC. This is quite common with this model.
