Unless you have alot of test equipment and alot of patience, it might just pay to put in a new one seeing you have it out already.

When the 4 blinks happens its indicating the Vertical deflection has stopped thats. usually caused by the Vertical out IC1509 (LA78045) and Verticak Buffer Q5A51 (2SC3311A) If you need further assistance let me know.

I have a Sony color rear video projector model# KP-43T75 it's blinking for time won't stop I checked for the Bolges on the black piece there is none and it turns on no sound or picture and shuts it se


First let me say that you did good checking for bad capacitors that might have bulges. They can fail with no outward signs though. You have to use a special meter to check them. Second that light means:
Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.


Your best course of action would be a new power supply board.

I have a Sony Color Rear Video Projector Model KP-57HW40. Its blue color is not working anymore and noticed some burn smell by the set which controls such blue color.


It may be the CRT drive board which is attached to the bottom of the Blue CRT. I would check that Board for signs of being burnt it may need to be replaced.

Sony KP-43T75 color repair


This link has the instructions on how to fix this problem and other similar problems. You have nothing to lose, so I recommend that you try it.

http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

This works with the two other colors, blue and green also. Not all models of Sony Projection TVs have the red, green, and blue pots in the same order as the picture that is listed on this link, so you may want to google search for your model's service manual. The service manual can also help you be able to remove the cover for your particular model of TV. I was able to find the service manual for my model, and sure enough, the order of the pots are reversed on mine, so I would have been adjusting the wrong color. Read all of the comments on this link too, because you can find other helpful tips and may even find someone with the same model of TV as you that gives more specific instructions for your model.

You may also find your model's service manual here:

I hope this helps you!

Fare well. :)

I was watching tv, turned the channel and the sound quit. I turned off the tv for awhile and still no sound, on any channel. Is there anything I can do to fix it or do I need to take it for repair? It is a...


the speaker may have quit working. or possibly if the t.v has a headphone jack something may be in the hole causing te=he t.v to send audio to the jack instead of the speakers. if that is not it if you do have a jack for headphones you can plug in an adapter to hook up your media to an external speaker device, the first place to look is this jack, if no sound will come through your headphones either thanyou have an internal problem
