I have a 50" projection screen tv model #

Open the front panel. Just to the left of the RCA imputs is a small button that says reset. You may need to use a pen or paper clip to press it. Press that and the system will reset .That should fix your issue, or do like me and get a Sharp. LOL. My bulb went out 2 times and I got irritated with it.

Hello:
This may be due to failure of the power supply or related circuits,the burning may of been a capacitor or capacitors that may of exploded, changing these will return the set to normal.

Reverse the AC plug from the set to the wall. Sometimes people will use a 3 prong adapter in which the hot/nuetral are reversed.

I would call Mitsubishi if you have the original remote the set may have (most do) a hard reset that will restore all inputs.

It consists of a 4 digit code by model number, I have a list of the codes somewhere(I am on the road today) and with the set on you enter the numbers and the set turns off and comes back on reset.

andychen993,

Depending on how you have your unit hooked up you may have a switch in the wrong position or not have a signal to the TV. Blue screen is the option if no video signal is present. Is your audio going through an amplifier? If so check all the signal feeds to verify that you have a signal going to the TV.

The easiest way to check this would be to hook a DVD up directly to the TV using a separate audio and video cable. If you still have a blue screen I would go into the menus and see if the settings are correct for blue screen.

If everything checks out ok then you probably have a bad small signal board and will need to replace it.

I have a tip at http://www.fixya.com/support/r4425498-basic_standard_tv_troubleshooting which could be helpful to troubleshoot your unit. It explains how to troubleshoot a dead TV but the procedure is the same to isolate a defective board.

Thanks for using FixYa and for the generous rating. We supply these answers for free.

You are lucky in that this is problem you can solve yourself with a little diligence. The set has defaulted to the 'Theater Mode'. It happens frequently with this model. It is merely a setting in the customer menu. Go into either SETUP or ADVANCED SETTINGS and look for something refering to 'Thearter Mode' and turn it off. An owners manual would help locate it.

I can help you unlock your Mitsubishi HDTV V-Chip.

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

I hope that helps.

no those tvs came with a black otuer screen that have rough ridges . If your screen is blue, someone may have replaced it with a dark colored plastic. You can get replacement screens at the following link, They are exspensive though.
