Question about Astar LTV-2701 27 in. HD-Ready LCD Television
My Astar TV has problems turning on for whatever reason. The green light will come on but the picture however will not. To get the TV to turn on I have to turn the main power off and on several times.
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.

This may be too old of a problem for anyone to still have one of these. I found that the computer control still functions, but, the screen circuitry warms up very slowly (like 20 minutes or more). If the TV changes to a mode that has no signal it times out and shuts down (See question about Invalid input message). The green light stays on and the screen dims. If you can get it in the right mode eventually streaks appear and tries to build a picture. Use the buttons on the front under the screen because when the TV gets this bad the remote won't be detected for several minutes. Locate the black switch on the back labeled 1 0. Flip it off and back on and full picture will return. The trick is knowing what mode its in. Change the capacitors as suggested

I know I am late on this post but I had the same problem with an astar ltv-2601. I just replaced 8 puffed up(bad) capacitors in power supply and has been good since about 4 months. They went out of business because they copied philips design and were sued by them. You get what you pay for.

I sold the ASTAR for parts and bought a VIZIO over 1 yr. ago-no problem. Bought a 2nd VISIO over 6 mos. ago. and love 'em.

EVERYONE LISTEN UP, REPLACE THE CAPACITORS, AND YOU'LL BE FINE. My 2701 was out of commission for 7 Months, and I just replaced the Capacitors. Now It was my first time doing it. Just reviewed some YOUtube videoson doing capacitor replacements/removal, and I was good to go. Just pay attention to where the Negative STRIP is on Capacitors and Solder away, and if you want an all in one solution, scan ebay for Desolder/Soldering Iron 40w/Solder Type in Soldering Desoldering and its about 15.00. GOOD TO GO

Eclip66 is right, ive opened up my Astar TV aswell and have taken a look at the power supply, all of the capacitors he mentioned have bubbled tops (means they are blown) or are leaking their electrolyte all over the board.. in addition to the capacitors he mentioned, there are 3 other near the center of the board with little plastic disks covering them.. i checked these using an ohm meter and found they were also bad (they charged WAY to slowly and were also leaking) so in addition to the 4x 3300uf 35v, 8x 2200uf 25v, 7x 1000uf 10v.. you need 3x 100uf 450wv caps as well. Im in the process of locating some replacement caps and am about to change them out, if this solution does not work, and i find more problems ill be sure to make an updated post.. happy soldering!
