This error is mostly caused by a defective line output transformer T511 (partnumber 1-453-308-31) and line output transistor Q533 (partnumber 9-948-014-40).
Also resistor R518 (2k7, SMD) could have been damaged.
All components are located on the main (A-) board.

My TV works fine with excellent sound and picture quality but the picture comes and goes?


Check all cable connections, if known to be good, then I would think it is a internal board issue. these boards some times crack connection from heat cycling, boards flex hot and cold.

The problem could be temperature related. I replaced both my processor board as well as the power supply board and the problem is still there BUT I found a VERY simple solution that just requires me to keep the TV on all the time. When the TV is at room temperature, it literally takes 10-15 minutes for the system to stabilize and provide a good picture and audio. When my basement was at 55° for a few days, it took over 1 hr for the TV to stabilize. I now switch the input to my Roku player input and leave the TV on all the time. The Roku screensaver kicks in and all is fine with the world. No more issues with the TV not working. It adds to my electric bill but it is cheaper than replacing another board. When the TV dies, I'll get a replacement TV.

Sound and picture go out after about 3-4 minutes. Then com back on after a few seconds then go out again and not return. What can this be?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Tv turns on but takes about 20 minutes to show the picture


This is the picture tube. If you check shops you can find one that has a picture tube restorer. If they run just the cleaning process it will buy you some time. This is good some times for up to a year
