Mom (fixer of broken things)

Sony KP-53V15 Sound comes on picture is delayed (no distortion). Worse when colder so opened up the set warmed circuit board with hairdryer and it picture appears with much less delay. Have inspected the two fuses and soddering for any defects (Used 3x mag lens). Nothing I could see. Any suggestions other than buy a new tv. My service guys says its not worth him coming out because no replacement parts are available on the model. (Manufactured Nov 1993) Thanks, Ann S. astein@rrmc.org

Hi Ann,
So far, for what you have mentioned doing it is very proffesional, as in our shop we use a hair dryer to warm boards/components also. The other item you are missing is a can of freeze spray ( component cooler ), which is a substance, when sprayed on the board/component does just the opposite of your hair dryer, it cools the circuit. When we are looking for a thermal problem, as you are having, we heat one board at a time. When we have heated the right board and the problem corrects, we know we have isolated the bad board. Now we have to isolate the bad part and thats where the cooling Freeze Spray come in effect. You can spray a small area of the board and watch the effects of the picture to see if the problem reacures. If it does, then you can heat up that board again and ellimante the problem and again using your freeze spray, spray only a few components at a time, thus finding the bad part. It takes a few times sometime to isolate the problem, but when you do, the satisafaction of being able to repair you own set is worth the work ( thus being the " Mom, fixer of broken things". As a precaution, the freeze spray can freeze anything it come in contact with like ( small fingers, eyeballs, irrate husbands ears and childrens parts, so be extra careful when you use it) and always keep away from small children and irrate husbands. I hope this has helped and good luck

My picture is distorted and fuzzy till it warms up and/or the front align button is pressed a few times.


Projection sets have two very common problems.

The first common problem is 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

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.

My sony tv KP-61XBR300 no turned on and blinks 4 times red light stand by.


This code means the vertical output circuit isn't working. If the set doesn't come on at all (no picture or sound), it's usually due to power supply problems. If you get sound but no picture, it's typically because of bad solder connections or parts failure in the vertical output circuit. My suggestion would be to have a professional servicer give you a repair estimate.

The most likely cause is shorted convergence chips and possibly a few pico fuses.
