The "tv" you bought is actually a monitor, meaning you need a cable converter box to actually watch cable with it.

Yes - the four capacitors that are mentioned are the correct capacitors - call 800-726-4405 to verify the info. akai LCT42z6tm

I had the same corner squares/scrambled display problem in a set just over a year old (of course). It became completely unusuable and I was not looking forward to a repair bill of hundreds of dollars. After reading these posts, I opened the back of the set and took out the board with the connections on it. (FYI, the cable connections were all hot glued down, but this did not present a problem - a little wiggling and they came free. I also took lots of digital pictures to make sure I reconnected it correctly.) This board had the four capacitors (C280, etc) mentioned in this section. Since I have not had any experience with soldering on electronic boards, I found a friend of a friend who was a techie and he agreed to look at the board. He replaced the 4 mentioned capacitors - although he said they seemed to be fine. He did, however, also notice that capacitor C336 in the same area of the board was bulging so he replaced it. SUCCESS. The TV is again working fine.

So if you are reasonably handy with a screwdriver, taking out the board is easy and makes transportation a lot easier than taking the TV to someone. The cost of replacing a few capacitors on a board was minor, and in fact, if I hadn't found someone with electronic soldering experience, I would have given it a try myself. You may, however, want to check for bulging capacitors (indicating a problem) rather than just replacing the ones mentioned.

You still need to replace C301. I can fix your mainboard if you need help.

A converter box isn't going to fix this problem.
Your TV is a Monitor. It doesn't have a built in tuner. That's why it doesn't have a Cable/Ant coaxial port.
The TV needs a cable box for tuning or some other outside source box for receiving signals.

Are you using cable from the cable company or an antenna for reception?

You need to do more torubleshooting, bad caps can look normal but they can have high ESR which are bad for switching power supply circuits.
Need to check the DC voltages, also try disconnecting the power cables to the backlights inverter board to see if it will come on normally isnce the light blinking can indicating it is sensing shorted circuits so it goes into shutdown/restart mode.

My 1080 P is having vertical lines run across the screen so bad that I can't watch it. After a while it will start working again. Any solutions.


Yes, it can be the T-CON board (more likely), or the main logic board, or worst case will be the LCD panel.
Try cooling the T-CON board first with small fan or freeze spray for electronics troubleshooting blowing in the T-CON board (the back has to be open) , it is under the metal shield taht must be removed.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Looking for free service manual or directions on how to replace power supply board for Akai PDP4294. Is it an easy install or does it really need professional installation. Also, where to get the part? ...


Hi kgee
Although this is not the exact service manual for your tv, it does have the same power supply.
http://www.wimtv.be/techniforum/files/ps42p3sx_ch._d58a.pdf
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

You may have bad capacitors on the main board where the signal is processed. These caps are as labeled: c280,c323,c302 and c320- replace this one first (it usually fixes the problem) Replace these caps with 100uf @35V
