I recently got a hold of a philips 60pp953217 tv. it has a convergence problem, so i replaced the ic,s both, stk392-120 with stk392-150. Before i replaced them the tv had a picture, after i replaced them the tv turned on then off. after turning it on and off 3 or 4 times, the power button remained lit, and there was a electronic tick from somewhere on the motherboard. no picture, no sound. could the new ic's be bad?
yes. replace them with stk-392-180. make sure you get good replacements there about 15.00 each. you can get them at www.wehaveparts.com. also make sure you did not solder two legs together.also check pico fuses around conv. ics.
I have LG rear projection TV RT-39NZ43RB. I had convergence problem six months back & I replaced one OF STK 392-120 IC. which fixed the problem. That time blue colour was out.
Now seems problem is back with green and light purple colour out.
Should I replace both STK ICs this time or the one which I didn't replace last time ?
To avoid same problem occuring again should I also go for STK 392-150 or may by STK 392-180 ?
This is the third post you have done on this problem. You only need to post once. This was already answered for you!
I have a phillips 55pw936317f it had a convergence problem, we fixed it, but we used the STK 392- 120 it worked fine for some time, but now has the same problem. My question is should i go for the STK 392-180 or should i use the same STK 392-120? Thanx
one very important question where did you get the ic's from on the first repairs??? And did you use enough heat sink grease on the backs of the new ic's???

have hitachi 43fdx10b have color convergence problem had same problem 3 years ago local tv shop fixed for 300.00. Same problem again. Would like to do myself what do I need and where to buy. THX
have a philips 2004 60pp9202 has a wave of orange at bottom of screen any suggestions
You must replace the resistors when you replace the ic's. If not you take the chance of destroying the new ic's you just put in.
Buying convergence chips from eBay isn't advisable.
