Question About Sylvania Flat Panel Television 6620LCT
6620 Sylvania special shuts down after 10''...

Well, Same problem here. Noted the top 1/3 of screen darker than rest of screen. CCFL problem. Inverter goes to over voltage shutdown because an arc can't get struck. Change the tube right? Well try getting to the SOB. Its the top one alright. But, not easy to get to. These must be throw-aways. It looks like I have to separate the LCD from the support to get to the tube. Those ribbon connectors looks like one-ops. I wonder how successful I'm going to be at this.

0 I have the problem traced to there being no output on CN401 driving one half of the backlight. Q425 has -1.9 Vdc on the gate where there should be +2.1Vdc but have not found the cause yet. Any known cure for this dog?
