Question about Akai LCT2715 27 in. LCD Television
One day everything was fine - next day we went to turn it on with remote and no response except the power light that usually turned green and the tv picture soon followed did not happen - the power light only blinked red. TV is only a year and a half old. Akai LCT2715 N 27" wide-screen.
I bought one of these tv's at a thrift store and it had the same problem, orange light blinking and static sound coming out of the speakers, no video at all.
The problem was the power supply board, this power supply has multiple outputs that feed the circuitry, 12V, 24v, 5V.
There was nine electrolitic capacitors I had to replace to fix it, all of them were bulged they are easy to spot, I measure one of them that was supposed to measure 1000uF but measured only 65uF. you can buy these from digikey for about 50 cents each, they need to be rated at 105 deg c and the profile has to be below the heat sink otherwise they will hit the top of the heat sink, the spacing between the leads has to be 5mm so they fit in the pcb. I replaced 3 1000uF/25v, 3 470uF/16v and 3 1000uF/16v and that fixed the problem, I bought this tv broken for 100 bucks fixed it with 6 bucks.
Good luck, don't perform repair if you are not familiar with dangerous AC voltage inside the TV.

To let you all know that Im having the same problem with my tv.. amber then red red red red... and popping sounds from speakers... Its because they use cheap parts there are 19 capacitors in the power supply (DONT RECOMMEND FOR NON EXPERIENCED PEOPLE) the 2 main filter capacitors are 100uf450v the ones in mine are just fine then there are 3x 1000uf16v, 2x 470uf16v, 3x 470uf25v, 2x 1000uf25v, 6x 1000uf35v, and 1x 470uf35v... Im in the process of replacing those capacitors. about half of them are leaking and 1 is blown... very dangerous for anyone messing around back there.. just thought i would let everyone know that its a 20 dollar repair if you know what you are doing i got my caps at marvac.com

These TV's are prone to power supply failure. I can fix the power supply on this TV for approx $100 +s/h.... Contact me and all you have to do is remove the power supply and send it to me and I will repair it with high quality parts. Reinstall and you TV will be good as new...

3 days ago started acting funny, would not turn on. I could unplug for 30 seconds then plug in and would work fine till next day. Now will not turn on at all, just get blinking yellow light and popping sound from speakers.
Can this be fixed or will it be cheaper to buy a new tv? (Maybe a Sharp or Zenith next time)
