Hello everybody! The picture on my Panasonic TX-55CRW854 has been gone for a few days, but everything else seems to work. Backlight worksThere is no picture at allSound works through both optical output and internal speakersStart apps works, Youtube app also emits soundScheduled recordings are made (TV switches on from standby)Stream from TV stations over the network works fine The background lighting is lit, but only statically, although the device has local dimming. It is only gone briefly when you start the YouTube app. I have already exchanged the T-Con board, but did not bring any improvement. There I can measure 12V voltage, so it should be fine. Power Supply Unit should be ok, I can measure 400 Volts. I am absolutely not a professional in electrical engineering, so your help would be great!
Hey Patrick S it looks like you almost got it handle. If you already switch out the T-con board then I would also switch out the video board. The video board sends the T-con board the image information to display. I would do that.
