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!

    The best clue given was the flash vertical. Your vertical output has cold grounds or rings around the pins. There is no contact there and, that is the first reason you have no picture. I ask that you have a tech or a dedicated hobbiest to remove the boards. It will take patience and a good memory to reinstall these!

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.

TV works fine for a while, then the picture disappears.


I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.

My VS-50609 Big Screen tv is showing only black and white


Maybe your colour setting is wrong or worse your color tube is no good. You will have to change the screen settings (color). If it wont work probably color tube is gone.
Good Luck

Mitsubishi VS-4541 too much red


The set is old and the picture tubes are probably weak. you can pop off the front grill, remove the protective panel to expose the picture tube sockets. On the sockets are controls to increase or decrease the intensity of the colors. The red is on the left ,green center and blue right. Go to a B&W picture or turn the color off, then adjust for the best grey screen.

Picture has greenish tint that I can't adjust out


There is a crt drive problem and you can isolate it by unpluggin g the set, removing the green crt socket, in the middle of the three tubes is the green tube by the way, remove one of the other tubes and switching the crt sockets and turn it on. If the set is still greenish, then the green crt is bad and needs replacement, if another color is primart, then it is going to be the green crt drive circuit and is going to need to be serviced. Good Luck
