Hi,
Please check same headphone jack at rear as input of PC sound in your tv because usually RCA jacks are not used as PC audio input. Normally same small headphone pins on both end is used to hook computer audio with external monitor.
Hope this info will help you.
Thanks.

akai is made by samsung check the samsung site

I know you are not wanting to spend anymore money, but here's what I did. I had the same problem and finally bought hundreds of these hard to find 3300UF 10v capacitors from china. These tvs are assembled offshore and quality and accuracy is suspect at best. It sounds like they put the wrong capacitors in yours which are severely underpowered. Capacitors ususally puff up when they are dead or dying, but not always. Perhaps you might want to try this.... I offer it freely and without guarantee, but it's better than ditching a 1200 dollar tv. I took 2 of them (caps) to my local electronics store and paid the guys 20 bucks to solder them in correctly. The key work here is "correctly". There is a polarity issue so it's best to have a pro do it. So for about 35 dollars I saved a 1200 dollar tv. The power supply for these things are over 600 bucks too. My electronics guy had a hard time finding these caps, which is why I went ahead and found them myself. My ebay listing is. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250615394136 You can buy 2 capacitors for 10 bucks plus shipping/hand. Suffer no further. Again, I was suffering with this same problem until I put the correct caps in with the polarity correct and took it home and now it runs like it's new. Just trying to help, hope I did!! :)

Hi kgee
Although this is not the exact service manual for your tv, it does have the same power supply.

As a matter of fact your akai is a samsung tv.
the replacement of that board is easy since it is all plug-ins and you can find that power supply in quite a few places,
Just google that part number.
Hope this help and good luck

Most likely one of the scan/buffer boards needs to be replaced to fix the problem. The vertical scan/buffer boards will be on the top or bottom of the plasma panel. It's basically the last boards that is connected to the screen panel itself.
You maybe lucky and its only a loose connection. Replacement boards can be found at a good price a E-bay. Just make sure the part numbers match up on the circuit boards.

Hi.

To start, as a qualified technician I would discourage users from repairing their TV unless they have a solid technical knowledge and experience repairing electronic.

The burnt capacitor story for example is a kind of Internet urban legend , that got popular thanks to the fact that a melting capacitor is a kind of fault that can be easily be spotted by any user without even grabbing a multimeter.

Even if a leaking capacitor is a fault that may happen on this or other TV, melting capacitors are NOT the most common fault on a TV (plasma or any kind), and there is a huge number of faults that can cause troubles on this kind of device.

The tons of complaints that you see on the internet are there just because owners use the internet when something with the TV is wrong. They post less when their Akai TV is working fine.

Akai plasmas are not known for scarce reliablility.they can fail like any other TV. If you put a popular brand known for being very reliable like Sony, you still will find a huge number of faults registered on Sony TVs and listed on the Web.

The PSU board is one of the most expensive parts on this set. RRP is about $400, here one from Sears at $192: Part# BN96-00249A


More parts for this set available here.


Here a service manual Akai TV. Most schematics are the same.

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or else revert for further assistance.

Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture. There is no sound, TV comes on and then after a few seconds clicks and screen remains blank.

Cause:

On the main power circuit board to Capacitors are prone to failure from over load. The caps are 3300uf 10v 105+c capacitors located to the left of the AC power input.

Service:

Magnavox will refer you to a service center. They will advise $$$ for an inspection. They will also want to charge upwards of 500$ to replace the entire board.

Solution:

1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.

NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)

This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.

Hope this all help, Magnavox is should take ownership for this problem and recall any tv's that have these caps in them. The worst part about this is that teh **** from the repair center that was paid 100$ to check the TV, stripped out the screw holes and damaged the case for the TV.

Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

Hi,

Please provide us with the complete model number of the product so that we can provide you with the link to download the manual if it is available online for download.

Thanks for using FixYa.

audio cables need to be hooked up as well not just a video cable.
usually red and white and clearly colored on the output side of the dvd player and the tv. input is on the tv output is on the dvd, also if you are using a fiber connection (optical sound) you will need a fiber cable from the dvd to the tv.

Try unplugging it for an hour or so or try change sources , if the computer ever fell asleep while it was plugged in it is possible it triggered a sleep mode in the tv. Most will do such a thing. It is doubtful that the computer caused any damage to it but i would advise against using a plasma tv as a computer monitor because burn in WILL eventually occur with a static image left on the screen constantly.

Hi,

Kindly tell me, what is the Color of LED? Do you hear any Click Sound? Is there any Pattern of Blinking?

Let me know, so that we could proceed.

Hope i helped you.

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

here's a possible fix, but at your own peril.

http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor

Look from the bottom of Tv to the top against the wall. You should see 2 screws on the bottom of the vertical bars they are safty screws so no one can lift it a little then off the wall. Also some mounts you need to pull bottom away from wall about 1 inch then lift.

i beat it with a big ******* hammer!!!!!!!!!!!!!piece of
