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 ?
You only need to post a problem once. It was already answered to.
