Usually this problem is caused by bad convergence ic's. These hold the three colors in alignment. They are better to be replaced as a set of two or three chips and must be soldered/desoldered into the circuit board. Most shops charge 200.00-375.00 to do this repair. I hope this helps. Most bow problems are from convergence or pincushion circuits.

This is a common problem on many brands of Projection Tv sets. Its usually a convergence issue. You can get more details and a solution here on fixya using this link http://www.fixya.com/support/r11932741-convergence_repair_dull_video_repair

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

TV click on and off.When it come on it has a green screen with lines. Stay on just for about 3 sec. than click off.


The green crt is dawning to much current, and that is why the TV is shutting down, if you remove the speaker cover, there is a focus block, that has six controls, on it three are for red blue, and green screen voltages, if you turn green down where the retrace lines go away, the TV should stay on, it is not worth fixing, you would be better off getting a new LCD.

Mitsubishi VS-5071 rear projection turns on, has audio but no video


That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.

No picture


Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

My screen have some red lines


I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt.red crt replacement is probably not economical to repair.

in the front cover turn up screens on all colors till you see retrace lines, then back them down to where dissappear. enless you know the correct voltage to set it. as for the green. i would try the red crt on the green and see if it looks ok. if so then replace crt circuit or check transistors on crt circuit may also need to change the driver on the heat sync.
