I work for a tv repair shop and we got three AStar LTV-3001 tvs given to us. in one of them we replaced the 8 caps (4 @ 2200uF and 4 @ 3300, which we actually replaced with 10 or 12 caps that added up to the same amount) and that fixed it. the other two need a MOSFET that is impossible to get ahold of. so they need the power supply replaced. i am currently looking for one and i will comment again if i find one.

Remove the back pedistal mounting screws and back cover. The PS board is under the metal protective cover at the center of TV guts, The CAPs that are referred will hopefully be identified by zjut soon but my guess it is the largest black caps 100uF 450W. 3 of them. around the transformers but wait for confirmation...

    Astar 30" LTV 3001--- Others have been replacing the 2200uF 25V caps All of them! I am going to replace all with 35V caps to have greater resistance to failure. 105C heat rating is also a factor. A set of 1" vent holes cut out of the pack panel will keep it much cooler and I may even add a small cooling fan.

    Tips, LCR meter revialled 4- 2200uF were bad, and 4 - 3300uF caps bad and 1- 1000uF(10v) cap bad, some were bulged on top and some not. If you don't replace all, you must test all. If you want to be sure and save time replace all 1000uF-10v, 2200uF 25v and 3300uF-35v caps. I would test the two 47uF-450wv just to be sure, these are pricy and harder to find. Remember to buy 105c rated caps and these are all radial type. Results in next note.....

    10 electrolytic Capacitors were replace and it has been working for 3 weeks now. Also, by mounting a computer fan on the rear, over the power supply will keep it cool, thus preventing cap breakdown from heat. Good Luck!

It's easily to fix the problem. Just replace the buffed capacitors on your power supply board.

    If you find the fuse (5AL @ 250V) was blown, then check the smart power IC F9222L. If this IC is shorted to ground, replace this IC also.

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.
