This set has 3 hidden menus accessed with a different 4 digit number code----You need the Mitsubishi remote to enter.
One of them is the Option menu which will allow a hard reset of the TV back to factory original---98% of the time it will restore all inputs--cures all sorts of odd problems.
If you have that remote and want to try it let me know for sure the model number and I will give you a link to the instructions for doing it.
This would appear there is no incoming signal. Check your antenna or cable connection is connected securely & then try to retune the TV once more, you should pick up a picture. If not, if you have a DVD connected via a scart, check if you receive the DVD picture. If this is the case then there will be a problem within the tuner stage, possibly a replacement tuner will be required
The repairs may cost starting at $ 75.00 to $100.00 for the estimate and basic trouble shooting the final cost of the repair may be about $200 to $400.00 dllars depending on the price of the part and the labor that is charged.
try pressing MENU 123 on the mits remote in sequence. then press ENTER on the remote and let it go through the system reset and see if that gets you where you need to go.

A common failure for those symptoms are IC9C25 a BA09FP which is a low saturation 3-pin regulator, Mitsubishi p/n# 270p677030.
Depending on it's failure it can cause slick raster, blue screen or what we refer to in the industry as a venetial blind effect. This is not the kind of repair you want to tackle yourself unless you're pretty competent in electronics and have some fair amount of test equipment. Reason is, although this may ultimately be the only piece of the puzzle it also may not and several diodes in that circuit could also be the cause. You would need to check for any leaks along that circuit and/or intermittent shorts that may have contributed to the failure of that IC..
Short version is take it in and have it looked at professionally. It's worth the expense and you'll save yourself a lot of headache if something more is wrong.
