It died suddenly after 14 good years. Can't turn it on. The yellow led in front turns on when the power cord is plugged to a power outlet. No reaction from the power switch. No picture no sound. I replaced the horizontal transistor ( it was shorted ). I suspected something with power supply, but with no schematic it's difficult to troubleshoot. Any advice with on troubleshooting or access to the schematic greatly appreciated.

Google is your friend. Just google model # dead! Check for an open pico fuse. Also, look here! Dani.

Antek: The schematics may be of little help unless you first can do some basic troubleshooting and testing without them. There are NO step by step troubleshooting procedures and the schematics are only most useful to those who are experienced in television repair. A dead set can many times be one of the simpler repair scenarios. Obvious first steps after your visual inspection would be dust off your DMM and to test the power supply components and look for properly regulated B+, in addition you should test the HOT to see if it is shorted and test for other faulty components in that area of the cicuitry.
