Question about Samsung HCM422W 42" Rear Projection Television
I chated with you earlier about my 42" projection samsung TV. The screen is blurry and bowed in the middle. Screen is normal size out on the ends then gets narrow towards the middle. The model # is hcm4216w. We had disscussed it and you said I should change the ic's(#stk392-040). I changed them both and the problem is still there.I have checked and double checked the installation. The board and pins look good. Any other ideas? Thanks Matt
There are resistors next to the skt convergence amps....usually they are about 10ohms.....they tend to have to be changed or at least checked when doing a convergence job...i've seen them take out a replacement set of STKs if not replaced.........or cause weird biasing problems if out of tolerance
