Probably have to replace both as a unit. Try Ebay if not available through Encompass or Fox.

SOURCE: Screen shakes / jumps vertically on my Sony KP-51HW40

The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

SOURCE: convergence problem for a sony kp-65ws500

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

SOURCE: sony widescreen projection TV -- Model KP-51WS510

The tv is in shutdown protection due to overdriving video signal. If you are handy you can pull the front cover off and there are 6 controls on a HV block. 1 set says focus, do not touch those. One set says screen. One at a time turn them down, counter clock wise putting each one back where you found itTurn the first one down and then turn the set on. Do this for each untill you get a picture. You will most likely find a bad blue gun. You can also remove the board from each gun 1 at a time with the set unplugged and find the shorted gun. good luck.

SOURCE: Sony wide screen projection tv model kp-57wv600.

I found this solution from SONY's website.

The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.


I hope this helps.

SOURCE: tv wont come on and a red light is blinking

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Sony KP-51WS500: This TV comes on for a few seconds of picture and sound. Then the picture fades to green and then turns off within another 10 seconds. Is this a power supply problem? Or should I look in...


Adjust the Green screen drive,turn it down and see if that corrects the problem.
Remove the Front Bottom Panel on front of Tv and behind it will be the Screen/Focus Control block
It will have 3 controls on Top for Focus to each Tube R/G/B
and under them are the Screen drive controls for R/G/B.
But if adjusting the Green Screen Drive Control does not Fiox It ,then you have a Bad Green Tube.

Screen turns red then shuts off


Sounds like a bad red projection tube, disconnect red tube socket and try again if tv stays on reconnect tube soket and adjust screen controls on front of tv under the front panel which you will have to remove to do any of this. There are six adjustment controls 3 are for focus for each color and 3 screen controls for each color. Look close at the black plastic control module should be labled R G B for focus and R G B for screens. Good Luck!

Sony rear projection tv model KP-53V15 turns on, have sound but no picture, after a while, picture comes on, but later goes out again, picture keeps coming and going. Where do I start looking?


Adjust Screen Volts (G2) of all 3 picture tubes and screen volt control knobs are on focus block located under speaker grills at front of TV.
Remove speaker front grille of TV, look for focus block that has 6 control knobs, 3 knobs are for focus and 3 for screen volts, increase volts by turning little bit control knobs of screen volts and this will solve your problem.

Blurry tv


there is a focus control in the front of the set behind the front grill there is a door in the middle attached by screws take this off and it should be right behind it. There are six controls on a little box one row says focus and the other says screen don't adjust the screen controls. In some cases these are in the back of the set.

Ok, thanks.
You should do following adjustment if you have enough experience of TV repair.
Please take off front cover of TV and find Focus Control Block, black part with 6 control knobs on it. You need to adjust Screen Volt of Red Green and Blue guns through Screen control knobs on that focus block.
Problem will be resolved.

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.

Congrats on changing the fly and getting it to come on. If it is a sony as it looks at the top of this page (accurate model?) need only to adjust focus and/or the horizontal static control. can't tell you where the horizontal static control is exactly but there are large wire associated. If not a sony then adjust the focus on the flyback.....top control bottom control is screen or for brighter picture.
