Hi,
I have a Philips TV model 20PT6245/37 (mfg 05/05) in my service shop with a loss of vertical deflection. I do not have SM.
For a moment after the TV is turned on, there is some vertical deflection, but it collapsed into a single horizontal line in the middle.
I checked solder joints at the vertical IC, resoldered them anyway, but this had no effect. Note: I soldered other joints too. Flexing and tapping on mother board has no effect.
I couldn't find pin out info on the vertical IC AN7225N on the web so I could make additional tests.
Thanks in advance, Brad
