Astar LTV-3001 I have one of these sets and I just heard a high pitch noise and then smoke came outof the top bak. It won't turn on now. Is this a symptom of a failed power supply?

Same thing happened to my astar tv. Your power supply is going bad, or at least some of the capacitors are going bad. Eventually it will go bad altogether and you won't be able to turn it on at all. You need a new power supply.

The failures on these LCD's are due to defective capacitors in the power supply. There are about 23 capacitors that will need to be replaced to restore the LCD power supply functionality. Check the picture to see where the capacitors are located, the power supply on your LCD is not the same but similar to the one on the picture just the capacitors are place in a different order.
Let me know if you required further assistance.

Ur Signal Tuner board is dead.Must replaced this board.Tries Shopjimmy.com,Ebay.com for the baord part.

There is no audio in DVI connector, you need to run separet cable for audio signal.

These power supplies are not longer being manufactured and very hard to find. The defective power supply can be repair.

Hello,
Try call my friend Ivan at 323-767-6030 he know where to get the original Astar parts.

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.
