Question about Mitsubishi VS-55707 TV

1 Answer

50" Mitsubushi Projection TV

TV stopped working the other day. I had been having trouble with my pictures fading in color. It seemed to get a bit worse as the months went by. I would give the side a little smack and the lines would ajust back in order just fine. However, just the other day when I pushed the power button on, it clicked back off within a few seconds. Not sure why?? Cannot get anything from the TV other than click on -- click off. Is it time to retire the Mits, or can this be an inexpensive repair? Thank you, Reginald

Usually what I find in those sets with that symptom is that the solder joints have cracked on the convergence output IC. When this happens you may see the colors no longer lining up on the screen, and slapping the side might temporarily straighten it out again. After a while the convergence IC will short out inside, which overloads the convergence power supply, possibly shorting a diode and/or burning the resistors. The computer senses that the power supply is not working right and shuts the set back off. When I make a housecall for a set like that I charge $150, but some shops charge up to $400, so ask around.

Hi, I have a 39" LG TV. Model number 39LN5300-UB. I just went through a hurricane in Florida and I thought the tv survived. I turned it on when I got back and it turned on, I connected my computer through...


Try removing each and every connector and be sure they are clean and dry, moisture can hide in them and not show issues for awhile...the ones that go to the panel are the biggest trouble makers...Good luck!

Sony Trinitron model # KV-27HFR- the picture is fading, is there a way i can fix that?


From your descrition the problem is the picture tube, over a period of time the guns build up crud reducing the emission on the front screen which in turn causes fading and progressively gets worse until viewing becomes impossible. One possible solution is to have the picture tube rejuvinated by a tv tech to buy more time out of the set, but the improvement may last a few days to several months or more.

Regular picture size shrinks and color fades


This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video. You can get complete parts and instructions from www.TvRepairKits.com

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.

Picture is fuzzy and color seems faded




Sounds like your coolant in the tubes need to be repalced. This is a common problem as the set gets older. Check with www.TvRepairKits.com for the supplies and instruction guide.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
