    Yes, I have the same problem. No display (just backlite) Audio works. I suspect the LCD driver board is bad.

    Yes, the fuse was the problem. With the help of "circuitcity" on ShopJimmy.Com forum, we diagnosed and fixed the problem which was in deed the FU101 fuse. It was showing a resistance of 30 Ohms when I checked it with a meter, which was abronal. Fuses should show 0 resistenace.

I got this from a person helping me

the no picture and good sound could be a combination of 2 defective boards in your TV, power supply or backlight inverter board.

1. If the TV turns ON, shine a light from a flash light near the screen and look for a dark video in a 45 degrees angle, if you see a dark video in the background then the power supply supply is not providing +24 volts to the backlight inverter board and will need to be repair.

2. No dark video might indicate that the backlight inverter board is defective.

This type of repair is not a DIY. If you open the back cover of your TV and remove the power supply board; you might be able to see the leaky or bulging capacitors.

The illustrations from the link are good for a LCD using 5 and 12 volts only but your LCD is using 24 volts to power up the backlight inverter board and computers power supplies do not supply that voltage.

So i took pics of the power supply Here

But then i read how u replaced the fuse... how did u.... exactly

can some please give me a guide...please email me at smv244@gmail.com

I just want my tv to work... also please email me the service manual..or does any one have a board...please help i just want my tv to work

SOURCE: I have Akai 37" LCT

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

From description it looks like a faulty inverter, I think that is the first part to test.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

AKAI LCT 2060 was working well as a TV. Just hooked it up to my PC and the message on screen reads "No Signal" Checked monitor cable and it's good. checked old monitor and it works well. Why...


The display settings on your computer need to be turned down. Set it to 800x600 and move up from there, if the resolution is too high - the TV won't display it.

Most failures on this TV are due to defective power supplies. If the TV does not turn ON, you should replace the power supply.
Check this website to buy the power supply adapter and hopefully that should fix the TV.
