Question about Mitsubishi Televison & Video
It is flickering after watching or a few hours and after a week it stops working then it works again after sitting
Its a older set so most likely bad or poor solder connections may have developed on the circuit boards, it comes with age and is rather common and not too hard to fix.

No video but good audio Mitsubishi VS5051. Check R509 and R 519, 100 ohm resistors located on the main PCB near the flyback transformer. Also bad connections on any of the yokes and the vertical output IC will cause the same problem.

SOURCE: TV Shuts off by itself
If you are lucky, it's only a blown fuse. Some tv's this large have more than one fuse, so look real hard and find all fuses. If fuses are good, then about 95% of the time, when you have no picture/no sound, the problem is a bad H.O.T. This is a large transistor with three pins soldered into the main board and is very easy to find because it is connected to a metal "heat sink". Look for a large red or black wire coming from the pic tube down to the main circuit board (sometimes it's blue, but it's the only wire coming from the GLASS part of the tube to the board. This wire goes to about the largest component on the board called the "flyback transformer". It is usually black and is about 3 or 4 inches tall, 2 inches wide, and 2 inches thick. The h.o.t. will usually be located in the area of the "flyback". The h.o.t. will be screwed with one screw or clamped onto a large piece of metal (usually silver). This piece of metal is usually about 2 inces square and is about 1/8 of an inch thick and is mounted perpendicular to the main board. Imagine a slice of bread standing on one side rather than lying flat and this is what the heat sink looks like. Sometimes you will see several heat sinks with transistors screwed into them, but the one you are looking for will always be the largest transistor with three pins. Don't forget to unplug the tv before you begin and stay away from the large wire coming out of the tube going to the "flyback". Do NOT unplug this wire from the tube. It can shock you very badly EVEN WITH THE TV OFF FOR SEVERAL DAYS. Just be careful and go ahead and give this a try. You can do it, and this is probably going to fix your set. If not, then replace the flyback transformer. The H.O.T. is about $10 or $15 and the flyback can be from $30 to $80. It is possible that none of this will fix your set, but you have about a 95% chance that it will and with such a big and nice and relatively new set, I would give it a shot. Keever

This is the most common problem for rear projection tvs and it is known as the color convergence problem.You will need to replace or repair its ics to solve it.

could be the flyback as some eat them depends on how old it is, and what model it is be more specific. also possible high voltage divider box
