Question about Sony KP-51WS500 51" Rear Projection Television

1 Answer

Picture alignment is off and the bottom and top are cut off

I think I may have knocked the picture tubes out of alignment.  Would I be able to open up the TV and align them myself?

Hi, if you haven`t opened the covers yet your tubes are fine .. you can`t move them without removing the rear covers, if you have a 3d look ie; colors are seperated your convergence circuit has failed, stk`s will have to be replaced which requires soldering equipment, video-tek

Without seeing a photo it sounds like the picture is letterbox with top and bottom black areas---if not that it sounds like a possible issue with the optical light engine the set uses to project the image on to the screen----most of this is not customer repairable.

Hi, I have a Hitachi 43FWX20B and the picture shows no red. I opened the servce cover and the red lamp does not light up when the TV is powered on. The other lamps light up just fine. I think the red lamp...


As you said your set uses 3 crt's red.blue and green.. not lamps.. If the red is not on it could be for several reasons other than the crt itself. From the driver ic located on the crt driver board attached to the neck of the red tube. It could also be the high voltage block or the anode lead going from the hv block to the crt itself. These carry a hefty voltage and will knock you on your but and make every filling in your mouth light up lol.. I recommend you having someone experienced check it out. As for the fluid, if the picture was good before it went out then that wouldnt be something to worry about. Removing the tubes to refill with fluid requires a massive alignment job afterwards.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Picture is concave on top and bottom. With ed and green ghosts.Worked fine, turn set off and on about 15 minutes later and picture was as described. Help!


The convergence chips in your tv have gone out. They control the three picture tubes and align them so that they create one picture on your screen. I recomend having a qualified technican replace them and realign you convergence. Thanks.

Picture cut off


No adjustment needed on these LCD projection. Your problem is in your setup menu. Your default is now is set ZOOM. That is why the bottom of the picture is cutting off. Go to Menu, setup and screen size or something close to that.

Best regards
