    Thank you very much for trying but I am not following the information in the pdf. file. The tv is an Astar brand and that board has nothing to do with the power supply for the LTV-3001 Astar flat panel HD lcd tv.

    Please try again I really need the help.

I need a replacement circuit board for my Astar LTV-3001.. Mine began to smoke... and I don't allow smoking in my house...


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.

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.
