Hello more than likely you have lost heater voltage to your CRT, also may of lost High Voltage, but usually when you lose HV the set will shut down. This model is notorious for open Heater voltage resistors.

Have a technician come out and confirm.

VS-5042 Sound but no picture


It is not bulb, are you talking about the tube ? At the neck of the tube you will see some connections.Carefully abserve if any cracks on the solderings(we call them DRY SOLDER), then connect them with soldering iron. Always make sure you have disconnected the TV from the mains. If the problem still persists, you will need to reffer to a qualified and Experienced person. He need to look for the LOT section(Auxiary power supply), video amplifier, CRT sections.

Mitsu vs-5042 Works then picture goes out. Thumping works sometim


If you occasionally have a picture then you stand a good chance of repairing this tv. There are bad grounds on the deflection board. Start with the board that has the flyback. I do not know the year of your tv. Sometimes the same model may have an option improvement than one couple of months earlier. The first suspected problem would be the vertical IC. In some cases this ic is located on the convergence board and in others the flyback board. It has seven pins and is the TDA version. Located on a large heatsink. Resolder this and any other grounds on both board. Some will tell you the P I P board is bad. This is a free standing board that can be removed and replaced. But please do the earlier option first.

Sounds like you need to clean the lenses and reflective area inside your set. It is easy and all you need is a screwdriver, windex and a paper towel. UNPLUG YOUR TV.   Take off your screen and screen protector and safely set them aside. 
Clean only the lenses ( glass part) and the reflective mirror type area on the top of the inside of your set.  It will look like new. You need to do this at least once a year.

Is my picture tube going?


Most proj TV's of that type have 3 Picture tubes Red, Green and Blue. It's not likely that all 3 went bad at the same time in the same manner. So I believe you have a circuit problem, probably in the power supply stages, possibly a bad solder joint.

Hope that helps...

Cleaning lenses/lamps on mitsubishi VS-60805


A can of compressed air might do the trick. If dirt is stuch, I'd suggest useing the same chemicals/cloths/etc you would use for cleaning camera lenses. Check at your local photo store.

Just make sure the lenses aren't hot when you apply cold and/or flamable chemicals.

Mitsubishi VS-60705 - picture flutters vertically and horizontally


This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.
