Re: LCD advice on a Phillips 40pfl7705d/f7

Well thought I'd check back to see if there was any other advice posted. I did play with flexing the board and it resulted in no change. I built a holding fixture to hold the tv at a slight angle with a mirror placed under it so I could see the pix while the set was running.

I have examined the tv, as this unit is less than a year old, I didn't expect to find anything too far off spec. All the voltages are within spec and clean when examined on a scope. I looked for parts...
