I had the same problem... Astar 30" LTV 3001 ....These TV's have a cooling problem that causes premature electrolytic capacitor failure. De-solder and Test all the 2200uF-25v, 3300uF-35v and 1000uF-10v caps in the power supply (center board, back of TV). Use a good LCR meter that will read 3300uF or better, Replace all bad caps with 105c rated caps. If you don't have an LCR meter, replace all the mentioned caps on the PS. If fuse on board is blown, also replace the F9222L regulator IC chip. Mounting a small cooling fan on rear of TV over the PS will help keep your new caps from failing again. This requires holes in the stand bracket and the rear of the TV, power can be supplied from a 14V source near the bottom of the PS board.

I am repairing Astar 30"LTV, but I can't find 100uf-450v and 47uf-450v high temp. 105 deg C radial electrolytic capacitors. I need 3 of each. Frustrated tom.
I have the same TV with the same issue.
Boonys - can you post a picture or diagram showing the 14V supply you reference?
I have the same TV with the Same issue - it sounds like adding a fan is the way to go once it is repaired. Boonys, can you post a picture or diagram of the location of the 14V supply you are talking about?
