Question about Sony KP-51HW40 51" Rear Projection Television

2 Answers

Sony KP-51HW40 I have 4+ year old Sony KP-51HW40 to which we recently had some work done by repairing some parts on the convergance board (pic appeared 3D). Fewdays after being fixed by technician for the convergance problem another problem appeared. TV shuts down by itself. After turning the power on the screen appears blue then turns black and the TV turns off by itself, all within 5 -10 seconds time frame. I have noticed that the power indicator light in the front blinks around 8 times followed by a pause. Any soultions? Thanks

Unfortunalty I'm not sure how to resolve you current problem. It appears I'm following in your foot steps with the convergence issue (image appears in 3d). I would really appreciate knowing how you resolved this issue (including cost) and if the two issues are related. good luck

I read it online that this is a very simple problem. It needs highvoltage splitter. I tried to open the front panel to see where the splitter is. However, I need some hint as to how to open the front panel. Good luck. Kiran

We own a Sony Sony kp-53xbr4ct and recently the image on the screen began to look like a 3d picture with red and green colors. Some research on our end points to a convergence problem. My question is...


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

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. 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.

Picture of a set that needs the fluid changed.

Sony KP-65WV600 Convergence AD Board


It should be a 4.7 OHM if its under the heatsink near the convergence chips.

You can do the repair yourself using the following instructions.

KP-51HW40 - Picture not Clear


Your problem is a typical convergence problem that happens on almost every tube type projection TV set ever built. There are two Convergence amp IC's that need to be replaced. If you have no TV repair experience, play it safe and call in a pro to assist you in this. Good Luck
