Check the cables that run from the main board to the switches and the manual buttons on the set, sounds like a cable needs to be reseated, or could be pinched or crimped

Hi,

I am sorry to hear regarding the problem.

As i do not have the luxury to examine your TV myself, i cannot provide legitimate 2nd opinion, however i would be able to add few inputs. I agree that this is not a ' quick ' fix. There could be few probabilities that strike my mind. This is an ongoing issue with almost all the brands and models including Akai, Panasonic and Sony. This is highly suggestive of a driver board failing. There are 2 main boards in this unit namely Y SUS and Z SUS. The one on the top drives the top half of the picture and the one on the bottom drives the lower half of the picture open the ribbon cables make sure to clean it or Re solder if you see needed turn set on and test, sometimes cleaning this will fix problem sometimes re soldering will fix problem and last resort is, the board itself is bad or the panel.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

There is either a bad remote sensor in the set or a system control problem. Both work with each other so it is hard to say. It will take a little troubleshooting to figure this one out. I would bet on the remote sensor being bad. Have a repair shop check it out. This should be an cheap repair. Thanks

try unplugging the cable devices from the wall outlet for 24 hours, it may possibly reset when it is repowered.

There should be a quick setup guide that came with this unit,

to get the tuners going you need to follow the procedure for setup, (as the stations will need to be found).

 

probably along the lines of press menu, select Setup, choose tuning, choose auto setup.

 

You probably have done this already, but does no harm to ask.

I HAVE PROBLEM,THE SCREEN SAYS AUTO SELECT SEARCHING,THEN NO SIGNAL FOUND THEN THE TV TURNS OFF BY ITSELF

Akai PDP-4249G... | Answered on Jul 30, 2008


Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

The speakers of the Akai is good so it is tempting to open it louder hence the chance of damaging higher. Try this to find out if your speakers are damaged....... raise the volume if no sounds, 1. remove the cable connection of the speakers from the TV whilst still connected to the speakers. 2.use a 1.5v battery to bridge the free ends of the disconnected cables, if you can hear sound...scratchy sound then the speakers are not damaged then 3. Connect a new external speaker to the TV if still no sounds, post back a message

Hello drifter,The design of the tv enables the auto search to detect any input signal you have selected. It could be TV (off air, video signals etc) so just switch on whatever inputs to the akai plasma befote you switch the Akai plasma on and let it do the work for you. just relax and watch the tv. recap 1. switch on the input eg video deck, DVD, VCD, or satellite dish. 2. switch on your AKAI PLASMA and 3. wait for the akai to search for your input signals. TRy this simple procedure and if it doesnt work just post back the message. The DON

Yes, I seem to have fixed the problem on my Akai using some creative google finds. One of two things worked - not sure which:

1. Leave the set unplugged overnight - it must let the electronics reset when the residual charges clear
2. For my Akai (remotes and models vary), hit in remote's sequence quickly - brightness, freeze, menu, enter - this places you in some screen that offers a hard reset option. That didn't work right away, but i did it before the option above and then the set worked again.

My problem was really odd because it worked for the component inputs and you could see the video and TV signals inside the PIP windows, but not full screen as primary input. Why the TV could 'see' the signals in a PIP windows but not detect them as primary I have no idea.

Tip

RESET ALL CODES AND PRESETS


IF YOU GET LOCKED OUT OF YOUR TV OR ITS MENUS IN ANY WAY USE THE REMOTE AND 1-PRESS BRIGHTNESS 2-PRESS FREEZE 3-PRESS MENU 4-PRESS ENTER THE SCREEN WILL FLIP BLACK FOR A SECOND AND THEN HIT MENU A FEW TIMES TO BACK OUT OF THAT TASK. THIS IS THE UNIVERSAL V-CHIP FOR THIS TV AND MANY OTHER RESETS.

Do you have any kind of anteanna? Go into the user menu and choose channel, then choose air or cable then do a auto programming this will pull in all the channels that is available and save them to the memory

EHT or Extra High Tension is the power supplied to the final anode of the cathode ray tube.

The EHT is traditionally generated by the line transformer from the flyback pulse of the line oscillator/amplifier.
The generated high frequency high voltage current was from the outset rectified by a thermionic diode (eg. EY51, EY86) but by the late 1960s/early 1970s technology brought high voltage diodes and semiconductors rapidly replaced the old technology and the output from the line transformer then typically fed the anode via a semiconductor voltage doubler.

The rectified EHT was originally smoothed by a high voltage oil-filled capacitor but that was soon deleted in favour of spraying the outside of the CRT with a metallic paint and grounding it. This became the high voltage smoothing capacitor with the glass of the CRT being the dielectric and the final anode the positive pole...

is it working ,i want the code

Check if the channel is off-the-air due to an issue at the transmitter. After a severe storms, some local stations lost their transmitter because the tower fell. More often, the transmitter hardware can fail. One station repeater near me had an interesting period where it didn't get the incoming signal from the primary transmitter.

Check that your antenna hasn't shifted to point away from the transmitter. Reposition the antenna, if needed. If you have an amplifier on your antenna, check if that has been damaged. If it has been damaged, replace it. My household found that the antenna/splitter became a filter for one VHF channel when damaged by a lightning strike. The check was to connect the antenna to one TV without the amplifier.

The other common issue is interference. Has there been construction in your area that added a large building between you and the transmitter?

I hope this helps.

First try checking the "auto off" function. I am not familiar with Akai TVs so this advice is very basic. Use the 'Menu' button and find Settings, (It might also be listed as Set Up). Go into this section of the settings. There should be a feature listed as 'Time' or 'Timer'. Set this to Off.
Your other option, if it is a brand new TV is to contact the store you bought it from and ask their advice.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.
