LCD TV Akai 27" NO PICTURE, NO SOUND, JUST A POWER LIGHT

My Aksi LCT2721AD LCD tv does not turn on.The power light is on,NO Picture and NO SOUND.I looked real close in dark and no pic, so it's not the back light.The built in DVD doesnt accept dvds.I opened it up and no leaking caps, or even slightly cracked capacitors /condensers,I looked real close.Nothing visibly wrong with the power board.No warranty and I live hundreds of miles from repair man.Can I use a conductivity setting on a multimeter, to test these capasitors/condensors,or do I have to buy a ESR monitor.They look fine though.I really looked close for damage.Please help. summerlander2005@yahoo.ca you can answer with one of the buttons,don't have to email me.Thank you

SOURCE: my akai lcd tv model lct2721ad sound will not work.

We need to verify if the problem is in the preamp or poweramp sections. Hook up the powered PC speakers to the AUDIO Line out RCA jacks and verify that sound is OK there, if it is OK, The problem will be in the power amp sections that drive the speakers. If it sounds bad at the RCA jacks, the problem will be in the sound processor board which mean the main board will have to be replaced, same if the power amp is bad.

Akai LCT2721AD TV just has a red light on. it wont power up at all.


I had the same problem with mine. I took the back off of it and found 3 blown 1000uF capacitators in the power supply. I replaced them and now it works fine. Cost me about $1 compared to $100 at the shop.

Akai LCT2721AD - Power on - Sound on - Black screen (No Picture)


Ive reviewed and assisted anoter person who had a similar problem that caused the tv to malfunctioin simialr to yours. After doing some short research and the other person who had the problem, came to find out that 4 resistors failed on the main board causing this to happen. It also could be the backlight of your Plasma screen tv, or your Plasma screen itself is shot.

I would recomened that if you have no active warenty to give a visual inspection of the Tv, via removing the rear black plastic pannel to see if any of the corisponding chips have any burn marks or excessive heat stress. these items seem to be failing about the 12 month mark

Good luck

Akai lct2721ad flashing red light


I would bet on the power supply....these (and other Akai LCD) are notorious for filter capacitors. Look for electrolytic capacitors with a dome-like bulge on the top of them. They are usually located at the top of the power supply board where the power output lines run out.

 

Hpe this helps you out....
