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....

SOURCE: subtitles disappear below bottom of screen

Check to see, what format the television set that widescreen etc. this may be all that's wrong with your set. If the problem persists the vertical height needs to be adjusted.  Most likely through the service menu, if units under warranty you can call Akai.  For further structures.

SOURCE: power light blinks red - tv will not come on

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.

SOURCE: AKAI LCD TV - power light stays red, won't turn green

hiii.....
If the power supply is supplying the main board with the correct amount of volts, your controller board or your on off switch panel is malfunctioning and needs to be replaced. If its the whole board your looking at a few hundred unless you can find the same tv with a broken screen and just swap parts.The on/off switch board is cheaper but you have to remove alot of interior parts to access and becomes a hastle.
thank u rate me!!!

How do I fix akai TV model #lct2785ta? TV screen remains blank and black, after I power it on.


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

AKAI Rear Projection 46"TV has a blank picture with sound only


Hello,


Is it a CRT or a DLP/LCD projector? If not a CRT, a worn-out projection lamp can cause this symptom. When it is a DLP projector, a faulty Colour Wheel sensor can be the additional problem. If it is a CRT projection unit the High Voltage and deflection circuit must be examined...

Please tell me more about your unit...

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Akai lcd 2oinch tv


Your power supply is bad. This model came with a bad design. Your supply may have a green light on the black box, but it is putting out low voltage or amps. Replace it and you should be good to go.
