Akai LCT2785TA - Where is the inverter?

My Akai LCT2785TA TV turns on, audio works, just no picture. If I shine a light on the display, I can very faintly see the image. Much googling tells me I likely need to replace the inverter. So, I opened the back of the TV, and, I'll be honest, I don't understand where the inverter is. I can see what I believe is the power control board and the main board, but no inverter. Can anyone help or do you know where I can find a diagram? Thanks.

Hay the inverter board is under the subframe that the main and power boards are mounted to.You have to remove the main board "big long board in middle" NOTICE the cable,top center of main bord wich runs under main board,wich is connected to the inverter board! So becareful when lifting the main board.After you have removed the main board.Remove the screws around the sides of subframe.Unplug cables as needed.Hope this helps. NoSugarTonight

Diagrams are not to be found for most modern sets as they only sell boards---

google the model with "parts" to locate the board which in most cases will have a photo of it---then you know what to look for

    I've already done that and know what the inverter looks like for my model. However, it must be in a non-obvious location because I don't see it after removing the back and yet another panel that exposed the main board. There's yet another level of casing where I believe there are more boards, but I'm hesitant to fish around to figure out how to get in there. I'd rather know what I'm looking for and know the way I'm going about it is the correct way.

Have you guys checked out my solution in the troubleshooting and support for this same Akai model?

SOURCE: i need help tv lcd akai model lct2785ta

You do know that this model TV takes about 5-10 seconds to come on after you press the on button, right?

Press it once to get the green LED, then wait. If it doesn't display the blue AKAI splash screen within 15 seconds, the TV is not working as it should.

Also remember that this model has two RF input jacks. As seen from the back of the TV, the jack on the far right is the one to use for analog TV, analog cable, coax out to TV from a cable box, or rf out from a vcr.

Don't use the one on the far left. It is for input to the ATSC OTA DTV tuner only.

Most likely there is a real problem with your TV, but in the video, you are pressing the on/off button in rapid succession. That will never work with this model.

Tv was working fine turned it off and when i turned it on all i have is sound on picture


Most likely you have a bad inverter PCB. The inverter lights the backlights so that the LCD portion can be viewed. Shine a bright flash light very close to the front of the set while it is on and look very closely for a picture around where the flash light is. If you can see any little bit of picture it is the inverter. If not the LCD panel is bad. Thanks for using fixya.

Green light is on but screen is black


It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

AKAI 27 Model #LCT2785TA


The message you are seeing means that the tv is not receiving a signal from the source. Try hooking up a different source such as a DVD player or a Cable Box to that same input on the tv. If you have picture and sound then the problem is with the original source. If that does not work then you have a bad Main bd.

Sound but no picture on a akai lct3201td


There could be 2 failures with your TV:
1. The power supply might no be providing 24 volts to the back light inverter board or the voltage is low.
2. If the voltage is normal then is more likely a defective back light inverter board.
The best way to know if you have a back light inverter problem would be to shine the light from a flash light near the screen and observe it from a 45 degrees angle and you should be able to see a fainted image. No image at this point might mean a power supply failure. If the image is there but fainted, then the back light inverter board is defective.
Let me know if you require further assistance.
