I replaced almost all capacitors on the power supply board. All of them Panasonic, same voltage and capacity as per the originals and 105 degrees.
Replaced C807, C810, C814, C819, C848, C846, C850, C852 on the mother board (and some others I don't remember now...most 220uF. ...just in case). Started the box and everything was OK. It just worked for 3 or 4 hours and then stopped with the date on the display (it was in stand by). No more reaction with the remote control. From this moment no way to restart it. Check power supply on connector 5V, 12V, 5v2 (3×), 3v3 (2×), 5vS. All OK. Check voltage on fuse F803 = 1.28V (should be 1.24), on F804 = 1.24V. The voltage coming from the last regulator is only 1.45 instead of 2.5V.
No other problem found, no burned parts. All information concerning voltages found on the document made for
http://www.8a8f8.com present probably also on this site. Just one more note: I had problem with high frequency channels. Problem was OK after replacing C848.
Hope this can help.
