Astar LCD tv are famous using cheap capacitors in their power supply board as componnents,these capacitors are leaking gases,they bulges up,puff up.That why one ur tv is dead.The other tv is unstables changing channel on it own.U know basic electronics,and soldering?Take both of ur tv aparts.Searches all around the power supply board.Look for these bulges up,puff up capacitors,replaced these capacitors.Both ur tvs will work normal again.Or tries websites like Shopjimmy.com,Ebay.com to buy two whole refurbish power supply boards to replaced each one of ur tv.
did you check the power supply capacitors, all the models of astar had this problem. You can tell the bad ones because they are puffed up on top. This fixed my problem and many other peoples. They used cheap parts so cheap results, they are out of business
I have the complete kit of capacitors to repair the LTV-2701 power supply. These power supplies need 20 capacitors for the secondary side of the power supply and 7 for the primary side. I can put together the kit with the 27 capacitors as well.
Let me know if you need further assistance.
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.
OK HERE'S THE DEAL WITH THE ASTAR YOU ALL SPEAK OF THE PERSON FROM SOLUTION 3 IS RIGHT IT'S A POWER SUPPLY ISSUE WE'VE GOT 130 OF THESE I'VE FIXED 40 OUT 44 POWER SUPPLIES. IF ANY OF YOU HAVE SOME SKILLS WITH SOLDERING. THE MAIN PROBLEM IS IN THE CAPACITORS. THERE ARE 3 SETS OF CAPACITORS THAT NEED TO BE REPLACED. 4 3300uf 35v, 8 2200uf 25v, 7 1000uf 10v. ONCE YOU REPLACE THESE YOU SHOULD BE GOOD TO GO. THE OTHER 4 WE HAVE PROBLEMS WITH ARE STILL POWER SUPPLY ISSUES BUT ALITTLE MORE IN DEPTH WILL POST WHEN WE FIGURE OUT THE PROBLEM.
