I was given a Philips 46pp930217 for free. The tv had bad coolant and a convergence problem. The tv is only 5 yrs old so I decided to put the work and parts in. I did the all the repairs, including soldering all the pins in the stk IC. Problem is now no letting will show up on the screen. I dont see any subtitles and the menu will not come up so I can reset the convergence. Can anyone give me a little direction.
