CHANGING CHANNEL RANDOMLY
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
My AKAI PDP4249G TV has
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!!
PDP 5073TMC... No remote will work any function.
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
NO SIGNAL on TV
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 42 inch plasma
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,

Akai model pdp4249g
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.
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.
AUTO SIGNAL DETECTING NO SIGNAL
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.
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.

The reason you're not finding any bad caps is that's not the issue. If it was the set wouldn't power up then shut down, faulty caps don't cause issues like this. One thing that would have helped is the model number but I have a good idea what's causing your issue. When the set is powered on it goes through the boot log sequence, this is stored in the EEPROM that's located on the main board, chances are if you take a can of freeze spray and freeze the IC the set will power up as this IC isn't used once the set has powered on but it would only work one time but it's a way to confirm if this is the issue. If you have advanced solder skills you can order an IC and replace it for under 20 bucks, but it's not something easy to do without the skills or equipment, the other option is replacing the main board, however that may run more than it's worth so buying a new TV may make more sense
