This board has had a hard time due to fake components (I've fixed 3 since without issue, using good IGBTs, but this one is very sick still).
All IGBT's have been changed, and many other components. All IC's pass a diode check as given in Panasonic fault-finding guide, and everything else seems the same resistance as a good board, but the picture is as per the attached clip. May not be obvious on the clip but there is some image retention. This was intermittent for a while, but now solid.
Vscan, Vad and Energy recovery volts are all OK at 147v, 200v (to Vfg) and 113v (to ground).
Any ideas anyone?
Thanks!!
