Question about Sony KP-53V80 53" Rear Projection Television

Blue convergence on KP-53V80

Here's the problem. The auto-focus will not align the Blue. Iv'e tried to adjust the DF and G2 voltages on the Focus Pack. No luck there. I'm good with electronic, however I no longer have access to an oscilloscope. I only have a couple of voltmeter. (Simpson 260 type) Any ideas or should I just bite the bullet and call in the repairman?

Replace both of your STKs 392-120s.these are your convergence ics , I always replace with 392-180s better ics.this will fix your problem.

Have a Sony KP-65WV600, already replaced d board once, and replaced convergence ic's once also. Now as soon as I turn unit on, turns to red screen and shuts off, video that is, audio works ok, noticed...


Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

My tv seems out of focus and has green shadows as well....do you have any idea what could be wrong?


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 projeciton 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 photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.

Reducing voltage for Sony KP-51HW40


G2 = screen...On the screen controls behind the front grill, behind the hardboard. 6 pots, 2 rows of 3 pots. 3 for focus and 3 for screens. 1 for each of the the red, green and blue guns/crts.
To adjust: Run set, change to black screen with tv/video button. Dial each screen clockwise untill you see a color. Then counterclockwise slowly untill that color goes black, then stop. Do this for all 3 screen controls.
If you need to adjust the focus then bring up lettering. I use the QVC channel for this. Focus is done by eye.
