Mitswubishi VS-5077 TV - Display would work and flicker to black screen. We would wait awhile try again.....picture would work and then flicker and go to black screen. Now black screen w/ only volu

The most common issue here in the old sets is bad solder connections--the problem is you have to get the entire chassis free and up so bottom of boards face rear of set---look to power supply---a lot of 2 and 3 lead parts there from heat come loose from the boards and also to the middle of the set on the middle board.

If you are not able to attempt this the set is too old for a shop repair in my view as many parts for it are no longer available.

No color

Confirm to me the brand and model number AND if you have not tried it=unplug the set for a while and then power up and see if that helps.

The front cover that diffuses the color came off during a move and broke. The T.V. still works ,but we need to replace the front cover.

A new replacement screen for your model will cost nearly the same as a new LCD in a comparable size. Keep watching web sites like craigslist, eBay, etc. and you will find in time someone either giving theirs away or selling it dirt cheap and you can swap the screen.

I have a Mitsubishi VS-5077 the screen has gone black, it started out with the darker colors going green, I was having to boost the britenees, than a line would flash vert. across the screen, now no...

You definitely have bad solder grounds. I have repaired a few of these. You will need a TV tech pull the boards out and resolder them. The worst board would be the one on the left [signal board, has rca jacks. rf connector]. And they may as well solder the second board. You will have a restored TV when completed. Thanks for asking and show a few hands of support!

I replaced the convergence chip which fixed my main problem, but now am wondering if a faulty pico/resistor can cause poor color? Thank you,

pico resistors serves as circuit breaker like a open resistor cause your circuit to malfunction..poor color can be corrected by cleaning the three cathode lamps.wipe it with a soft cloth same with the projection mirror clean it with a soft cloth be carefull not to break the mirror.Ajust the color intensity of each cathode through it screen adjustment adjustment are place at the front pannel of your tv they are labeled screen RGB..GOOD LUCK!

please rate my help tnx.

Mitsubishi VS 4543, Picture go out after a few minutes

I usually find that symptom you describe is caused by cracked solder joints on the power regulators or vertical output IC. I have also seen that symptom caused by loose solder joints on the vertical windings up inside one of the yokes. If you have experience in repairing TV's then you can disassemble the set and pull the main chassis, flip it over and resolder all of the parts mounted on heat sinks. If you do not have experience in repairing projection TV's then allow a qualified tech to handle it for you.

Mitsubishi ws-55517

the outside screen is called a linticular lens and the inside one is the fresnele lens. They both should come out together from the front as the trim on this set if im not mistaking pulls or slides off then theres mounting plates holding it on. Becarefull and dont try to clean the mirror as the coatings on the outside of the mirror. Also be very carefull not to touch any componets as theres extremly hi voltage in these sets even with them unplugged. Good Luck
