Question about Sony FD Trinitron WEGA KV-34HS510 34" TV

1 Answer

Periodically there is a blue-green discoloration in the upper left corner of the screen. The labels, Video 1, Video 2, etc. which are usually a uniform green have the "V" and the "i" show up as blue. The same distortion is seen when there is a program playing. The problem disappears for a while if I unplug the power from the TV for a couple of minutes and then put it back in service.

Hi,
Question shows it is Sony KV-34HS510 tv that is picture tube (CRT) tv
Symptom shows tv has some strong magnetic field nearby, specially at top right corner area, please check any speaker or some thing that has magnet inside, remove that thing from tv to fix the issue.
Strong magnet will affect color picture tube and can cause different color in that affected section.
Let me know if you have additional question.
Thanks.

Can not get the focus grid to line up correct green adjusts fine but blue upper left corner will not adjust and the red grid is way off and will not fix


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.

Color issue


Replace 120k resistor on the blue video output module. Resistor is located next to the blue video output transistor (has heat sink). If you replace it with a 1/2 watt carbon type, it will probably never happen again. I recomend the same resistor on the red and green video boards at the same time.

Blue Convergence just went out?


High Voltage Capacitor? Leave the set unplugged for 1/2 hour most components will selfdischarge, as for your problem, being a Magnavox, you have one of two problems, the convergence I suspect is what is blown out, this unit probably uses STK392-110 Ic's, I would suggest replacing with STK394-160e chips as they are probably shorted, some of the big resistors (1 or 2) may be opened up also, usually they change color. The only other thing that would cause usually a yellow color in the corners is the CRT Fluid, it changes from clear to Orange in color and clamps off the blue color from the fringes, I suspect the chips need replacement, dont forget to put some heatsink dope behind them, they are usually on the left in the front of the set (from the back) Big long heatsink that is fairly tall (probably the biggest heatsink in the set.) Good luck, and the repair usually runs around $350.
