I have a 65 inch Mitsubishi rear projection HD TV. The screen went blank today. I have cable hooked up to the componant input and I get no sound or audio. If I hit input a few times I get static sound...

Does the input menu appear on the screen when you press input? If so its probably the IC Regulator 9v supplying the video board. If the green light on the front is blinking then powering off it is one of the 7 capacitors and you should just replace them all, 30-35 bucks. If the power stays on and its just your video isnt coming on(audio as well) it is the IC Regulator. Mine called for the part - BA09FP IC REGULATOR 9V It is about half the size of a pinky nail and located directly behind the video input board in the back of the tv. It has two prongs on the left side and one wide tab on the right. It solders directly to the top of the board and not through it. It says BA09 on the chip. This fixed the problem for me.

I had to unplug my cable/tv last night and when I turned it on this morning I could not get the menu to display the cable accept on the menu screen. I went in to turn off the home theater and the cable...

Push the menu button and enter 1370 and push enter and the tv picture will appear on the screen. If it does not push the input button until the picture appears.

I have blue botches ( ghosts ) appearing on the tv

This problem is caused by a bad optical block. Sony has extended the warranty for this problem but the extension is only valid until December 2008 so you must act now. You can find instructions for obtaining service and additional information here:

Glass or something behid the screen broke

Misha, I have bad news for you.

There is only one part behind that screen to break - a rather large mirror.

To verify:

Lay the TV down, face down, on a towel.
Remove the screw from the upper rar black plastic housing.
Lift straight off - you should see the mirror, or what is left of it, attached to the black plastic.

Sorry for your loss.

If you are interested in selling the ballast, let me know.

White arched lines appearing on dark/black screens.

it sounds like you are seeing the vertical retrace for all three colors together (white). Its possible that all three screen adjustments (red, green, blue) are off, but I suspect a problem with the screen power supply.
there is also a recall on this set
