TV is 7 years old and will no longer power up. Prior it shut off a couple of times while watching, but was able to turn back on. Yesterday, I went to power up and nothing... Suspect power supply, but wonder if anyone has had a similar problem.

Sounds like it's possibly your convergence IC's overheating. On some projection tv's, after time, the solder joints on the IC's weaken from the heat and cause them to turn off the tv for it's own protection.
Sounds like the capicator on the high voltage is swelled,removing the back cover,make sure to unplug the unit first,there is a u shaped heat sink about middle ways of the board,inside that heat sink is a cap,it will be swelled on top of it,its a 2200 35v cap.
If the convergence is missing in the menu in screens,you have a bad reg ic on the convergence power supply the part number is 215530,the power supply is located on the black plastic above the right module with all the heat sinks
The Gemstar board is most likely at fault. The part number is 241271 but, is no longer available. The Gemstar board is a small metal box with usually two white ribbon cables going to it. Alot of times the ribbon cables are not seated correctly or dusty. With no power to the TV disconnect the ribbon cales one at a time and used compressed canned air and blow ow the sockets on the Gemstar board and the main board. Make sure you reinsert the cables correctly as they only have conductors on one side.
