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.

    Evidently ASTAR lost a $100,000,000.00 Patent infringement suit with Philips and all of their assets were seized. As a result, parts for ASTAR products are no longer available. For all the gory details, check out post 14 at:

    On the bright side, the capacitors to repair a power supply board cost less than $100.

Will not power up. Replaced bad power supply(burned circuit board inside PSU) but still does not power up, PSU is ok. When power on button is pushed CPU fan turns for about 1/2 second but nothing else....

Sounds to me like when the power supply went out it allowed a surge to hit the mother board and you will have to replace it also .Look at the mother board and see if there is a green LED light showing if it is you are getting power to it and you have capacitors blown if not recheck you connections from the power supply and MB if they are all tight and correct then just figure on replacing the mother board

Green light comes on no picmor sound

Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

Suddenly turned off without warning Sony KDS-50A2000


All you need is to open the back cover of the television and check on for dry soldering at the power stage of the printed circuit board, also check for bulged capacitors, if found replace with same rating of voltages , but if otherwise Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hope this helout, Good luck....
