    TV vs-50705 just cut off. When powered back on there was a blue line stretching from the left side of the screen to 4 inches from the right side of screen.

    TV has horizontal "jumpy" lines through it when I turn it on. After left on for awhile, as if to warm up, the lines stop. It started about 6 months ago, and would take about 1 to 2 minutes to "warm up" and get rid of the lines. Now, it takes about 30 minutes, and the lines are much worse when you first turn on. Cannot even see picture. Any suggestions?

We need to know if the lines are of different colors or are they white and the screen is too bright ?, 275.00 seems a lot just to get it check out but it all depends were you are,in NY that could be a going charge but in pittsburgh it seems too much,please let us know what the lines look like.

My tv has horizontal lines till it warms up,only a couple minutes then it is pretty much clear.it is a 42 inch projection tv.Is it the bulb?

This is a sign that you should be looking for a new TV. Tubes are getting old along with components and it takes more High Voltage when first powering it up that cause these retrace lines.

Shaky picture once warms uphorizontal lines stream through it continuisly

there are some capacitors on the signal board that are associated with the pwer supply regulators off the 5 volt and other sources there that need to be replaced

if you have the tools and know how and soldering station you can do the repair your self if not then you might want to contact a servicer in your area
i can get you the cap location numbers if you like

Mitsubishi VS 5041 rear projection

if it has been four years since the set has worked you are going to ned all three CRT's I'm afraid, the tubes will go soft just from sitting and not being used. also I bet there are a ton of bad capacitors in this Tv set now also.

VERTICAL ROLLING, VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE, ALSO MAY HAVE HORIZONTAL PULLING OR TEARING. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2). CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.2). CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB. 3).

Horizontal lines and screen bounce

These sets have capacitors that will go bad, but without a good ERS meater that tests these in curcuit you could be spending a lot of time doing nothing, But the most common is to find the 9 volt reg on the signal board and change all within a 2 inches of that regulator

Code 23 means horizontal deflection failure. Check your horizontal output transistor. Or the horizontal drive transformer solder joints as well as the horizontal yoke pin connections for bad sloder.Hope this helps. if I can be of further assistance let me know
