Here's what I have my LCT3285TA is stuck at full volume and the 100% flashes as if a button was stuck , if I hold the vulume down it stops flashing but stay full 100% , this also seams to lock out making any other selections channel , source etc ,, I disconnected the Key Controler board ( buttons attatch to on side of TV) with no change,, I'm thinking static maybe from walking across the floor prior to shutting it off damaged ,,??? Cap?

"does anyone take any pride in what they do anymore ?" - Bullseye!

Take IrishDruid's link to that service manual website, that's the only way you can get a schematic, tried Google no luck.

Hi
After reading all the reviews. Just try a step to release the static.

When you unplug the power. Just Press and hold the power button on the LCD for 30 seconds.
Pug it in and try again.

I hate to disagree with you ID, but a stuck button CAN cause this type of behavior. Based upon the description here though, I'd suspect a power supply problem. Either the 5V supply is being drawn low (less than 4.3V) or there is a lot of ripple on the line which can be interpreted as information. In any case, this is not a problem that a novice will be able to trace. Also, schematics are not generally available for these sets. I have worked on some of these sets in the past with mixed results. You can often determine the problem area based upon the parts, but it is time consuming and not likely to happen at a service shop. They are more likely to replace the board.

You may have to bite the bullet and either sp[end the $700 for the replacement board or replace the set.

Since this is a digital LCD TV, there is no question of any button being "stuck". It is most likely an issue with the circuitry. You can try a hard reset first, which is the basic step. Unplug everything, including cables and power supply, wait about 1/2 hour and replug everything. Should the hard reset work, well and good. If not, you will have to take the TV in for servicing. I do not recommend a DIY if you have no prior experience, as there are very sensitive parts within.

However, if you would like to try a DIY, you will first need to get your hands on a service manual. I recommend the following site:
http://servicemanuals.vstore.ca/
They also help you procure the needed parts and provide free diagnostics and help while you repair the set online (provided you buy the manual from them, of course)

Hope that helps! If there is anything further I can assist you with, please let me know. If you are satisfied with my response, kindly take a moment to "ACCEPT" my solution.

Cheers!

Yes the board may be the issue, there are companies who sell parts but first you will need to know what failed, that is near to impossible without proper test equipment and a trouble shooting manual, I would suggest u leave this to a repair shop

Try to reset the lcd tv but if reset will not fix it then the unit should be taken to the nearest repair service center to fix it.

hope this helps.

The volume is stuck at 100 (max) and when I go to the menu button it just rotates through all of the options. When I try to reduce the volume, it blinks fast between 99/100 without an reduction.


It sounds like the a switch on the TV is stuck. This may just be a stuck button, or a bad Switch Board. Try moving the buttons around to stop the problem. If this doesn't work, you will probably need to replace the Switch Board.

Volume won't turn down


Try the setup program. When you get to the main setup screen, look for a reset all to standard setting. That may solve the problem. If it doesn't then the sound module may need to be replaced inside the TV.

Volume Control


check the up volume button on the set. it sounds like it is stuck in the on position. You can open the back and disconnect the wire harness to the control buttons. This will verify if the volume up button is the problem.

Menu Trouble


perhaps the volume down button on the TV is stuck. It could be either physically stuck, or the electronic logic could be messed up. Just to rule out a problem with the remote, take the batteries out of it and then adjust the volume at the TV and see what happens.

Volumne on Akai LCT3285TA


Often a signal might experience a super-quick "drop" in signal strength, and the display is automatically adjusting the now weaker audio signal to "mono" (temporary, as for best quality). But the dropout is usually so brief you will then see the "stronger" signal restored [full strength], and now the audio is "stereo".

It's like a "bump" or "disturbance" that occasionally affects the cable/satellite/OTA (antennae) signal being fed into the TV, and your display's attempts to compensate for the weaker signal [going to mono, then back to stereo once back to full strength].
Connecting it to your cable directly (bypassing the box) or an antenna would give you a true over-the-air signal, which would be proper MTS and would not give you any more pop ups.
