replace the blowen one, you can get them from mcm electronics. or thepartstore.com

It sounds like you did dammage the board, is it three blinks or 4, if it is 4 you may have taken out the vertical circuit, also make sure you plugged in the yokes.

The yokes are the coil of wires on the neck of the crt's (the glowing projectors) there are wires that need plugged in if they are not, you can get a 4 blink error. If you verify that the yoke plugs are in, then you may have blowen ic8003 or dammaged the 15 volt line. The fixes that are presented here are usaly common problems that tech's run into. but now you have a situation where you need to troubleshoot the symptioms to find the problem. you now need to make live measurements, you need to check pin 4 and pin 6 of ic8003 for the presence of -15 on pin 4 and +15 on pin 6. If you don't have these voltage you may have power supply problems that need fixed, if they do exist then change the ic. Also ic8003 could be loading down the ps so dis connectiong pin 4 and 6 before you test will give you a more accurate result. if you disconnect these pins make sure you measure the solder pad and not the pin it's self.

This is what i would have to do to fix this tv from this point. Get the above diagnostic, then move to the next diagnostic point.

sorry found ic8003, but it only has 4 pins

So magically everything started working, and we started to correct the course adjustment and have green and red working, when we tried to start altering the blue adjustment, which is way off, some of the course adjustment adjustments do not alter the grid on the screen, the ones that dont work are lin, size, skew, center. I have also noticed that the IC8002 seems to be running significantly hotter than the IC8001, both have industrial heat sink compound on them. What should I do now

i just aquired a kp-43ht20 projection tv wiht a convergence problem picture looks clear enough just there are three of them in dif colors lol they say they just spent close to 600 to fix then it goes out again they went to a flat and give this to me is it worth fixing is it cheap etc can you help me i have an internet phone that is unlimited if nessicary

i got triple vision isnt there some way of lineing them up or does the chip do it my friend cliams i can reset chips to orig and it will line bck up ? false ?

I want to be to work on the D board on a workbench. How do I remove the red wires? I tried twisting the wires 90 degrees as per manual, but it still does not come out.
