Question about Mitsubishi WT-42311 42" Rear Projection Television
No, it's not a bulb issue - your tv is a CRT one, it has 3 small tubes like those on older tv's, when they fail the image goes dim, not bright. Since you also got a blue screen which signals the fact that the tv doesn't get the signal it means that the mainboard of the tv and all the other stuff connected to it is ok - it's an input problem, the signal doesn't reaches the image processor.
First you should check the tv by plugging something else in it, like a DVD or another player and using a different type of cable (like an S-Video one) . Or use even the antenna - if the image is correct then the fault is in the cable to the recorder (or whatever is the device you are using). If the cable is good then the recorder must be at fault - test it on another tv.
If the image is still bad then the fault is in the connection to the input sockets from the mainboard - take the back of the tv and inspect them all for loose solderings to their pins. I seriously doubt that you will gonna have to change even a single part.
