Power supply problems on an Astar LCD tv~model no.LTV-32HBG.On the power supply board no.7506T2627001AP;I found four capacitors:two(2)680mf/25v and two(2)2200mf/10v;these capacitors became defective I believe,due to two defective transistors-Q3 & Q15.The transistor number(on the component)is:40N03GP and I have tried to cross reference this number but had no success.I need a good reliable replacement transistor(x2) that will substitute for Q3 & Q15,ie;if the original part is no longer available.Thanks!

Power supply repair


I just finished replacing all 25 or so of the electrolytic capacitors on the power supply board of an LTV 2701 AStar TV. When I got done, the tv came back to life and WORKS GREAT. Every last electrolytic was either leaking onto the board or puffed up or both. The main problem is that Astar designed the case so that no air can circulate over the board and the capacitors bake after a couple of years. If you don't do somethig to let the air circulate, you will be replacing them again in 2 more years. The board is pretty sturdy however and its fairly easy to replace them all with some copper desoldering braid and a 125 watt soldering gun. Just be sure to keep the polarities right on the electrolytics and make sure that they are the 105C variety. Good luck and remember to add some fans and cut some extra holes in the cage.

Screen goes black immediately after astar logo screen comes on


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.
