Turn tv on, audio but only flashing pic, then turn off and turn back on same thing, 3rd time have full pic


Hi,
This problem will occur under two circumstances
1, Faulty electrolytic capacitors in the power supply board
2. Faulty back light inverter board.

Fist of all check is there is any faulty capacitors in the power supply board. If you find or not try to replace all the electrolytic capacitors in the power supply board. In most cases this will solve the problem. I have added the some video which will help you









The second one is the inverter back light inverter board. There is no repair possible with the inverter board. You have to replace the board with a new one. As you didn't mentioned any model number of your tv its not possible to attach a picture of the exact inverter board. The back light inverter board will look like one in the picture

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.

Lcd tv has no picture


The inverter pcb inside the tv has probably gone bad. The inverter lights the small fluorescent tubes behind the panel for back light. Take a bright flashlight and hold it close to the front and see if there is any picture. You have to be patient with this method and look real close. If you see the picture it is definately the inverter. Common problem. Thanks

TV turns on sound but no picture


Turn the tv on and get close to it and see if you can see ghost images. These will be normal images but will be very faint and look like shades of grey. You don;t want to do this in real bright direct light but a normal light or day light works. You can also hold a flashlight up near the edge and see if makes it easier to see.

If you can see an image and have normal sound then your problem is the back lighting system. This can be the lights bulbs or leds or the power supply for them. Repair cost should be under $150. I don't think you have any warranty left but check ASAP if you do as it may not last much longer.

If you have no picture and no sound then this is usually a problem with the receiver section. Can't suggest what cost would be as it can range from cheap to a bunch depending on what is wrong.

As always with any lcd tv or monitor make sure you know what a replacement is worth before you spend repair money. Repairs can sometimes cost close to what a new tv will.

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 On/Off Problem


My Philips LCD TV had the same problem. If your Voltage system is 110 AC till 127 AC and no transformator, then it is probably caused by one of the 4 main transistors, which are likely not originalfrom AKAI, but made in Malaysia or closeby there.
My TV works perfectly after 1. Replacing the burned or semi-burend transistors (in the back panel) 2. After repair (=US 60 plug the TV in a outlet from transformator set to 100 V.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....
