Philips/Magnavox rear projection problem

Posted by scott50 (My Page) on

I have a Philips/Magnavox rear projection TV, Model PTV840. I am having convergence problems. Bowed screen Red/Blue/Green colors out of alignment. Cannot adjust this within the Menu under Convergence. Is there a repair kit of parts that I can purchase and install myself that will fix this problem? Thank You for any help you can offer.

You will need 2 stk392-160. Replace on large heat sink. Also check all fusible resistors around the STK's/heatsinks.

I replaced both STKs. They were STK392-110. I also replaced all twelve resistors. Got them from an online store. Magnavox Convergence Repair Kit TV-KIT-008. All the same issues though. What else could it be. Any suspect fuses that may be bad.
