I'm not sure if Akai has made any of the sets that carry their name; some have come from Samsung and others purportedly by Funai but when I have tried to find service information on given models, it has been a dead end regardless of who made it. The true manufacturers refuse to recognize model numbers assigned by Akai.
If you had just burned resistors, I might be able to help you but when missing, you're kind of stuck.

Lightning damage

Replace the parts with the original ones, a .5 ohm difference on a resistor on the video circuits will cause the unit not to work correctly.

No power whatsoever, is the bukbs gone or just the power unit?

If you are not getting any power then the first thing to check would be the 2 fuses on the power supply board. Below is a picture of the power supply board with the 2 fuse locations circled in yellow. The fuse values are printed right on the board, just use a multitester to check to see if they are blown. If the fuses are both good then the next thing would be the filter capacitors on the power supply board. The second picture below shows the capacitors to check. Look for bulging tops, they should be flat. If any show signs of bulging then they will need to be replaced too. You can get a kit of the capacitors at this link:

I hope this helps,

TV wont turn on has no power

Hi Scott,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the link for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, check it online like and

Also, check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

The noise sounds like the power source?

I had the exact same problem with this monitor, same model & manufacture date. Another solution on this site promted me to replace 3 capacitors on the switching power supply similiar to the one pictured here:

Take apart the monitor, carefully unplugging the jumpers to the spkrs, USB ports, etc., and remove the power supply from the internal cage. I desoldered and replaced the following capacitors/values from the board of the power supply:

C5 = 680uF 25V
C17 = 680uF 25V
C10 = 1000uF 16V

I picked these up at an electronics repair shop for $3 and spent about 1.5 hours with the entire process. It's a great monitor and was well worth the time and parts to get it working.

Blown capacitor but....

Be sure you replaced the capacitor in the proper (+) (-) orientation. There is a half moon shape line on the board on one side of the capacitor legs, that is the negative terminal. If incorrectly installed it will not work.

Very poor sound quality

After installing parts on a board some tv's require that you reset some values on the tv's servicing software. This software is only available to certified techs but you can search the net to try and find it. the caps that were replaced should be of exact value in 3 criteria:

1 Voltage
2 micro farads
3 temperature

Also a note of safety:

There are HIGH VOLTAGE circuits inside your tv that could inflict serious harm even when its unplugged if approached wrong. There should be warning stickers all over the chassis of the tv informing you of the danger that your exposed too. When you take out the primary power supply discharge all high voltage capacitors to cancel the harmful charge they are holding. Especially if you just turned the tv off.

Discharging HIGH VOLTAGE capacitors:
use a high wattage resistor of about 5 to 50 ohms/V of the working voltage of the capacitor. If you don't discharge the capacitors or replace caps with inaccurate values you could easily damage other sensitive circuits.

Try resetting the tv back to manufacturers specs and see if this produces better audio quality. And when ever your working on any circuit board be sure that you are well grounded. This will prevent ESD (electro static discharge) which can harm other circuits especially logic circuits. This will cause an imbalance in circuit operation and result in a non working tv eventually.

P4004 - Blown Components

if burned components are on output stage or amplifier section on board..Then look at the oposite side of amp..Both amplifier section should be a mirror image oof componentc from other..that way you can know the values of parts.If they are on power supply section ..Then you might need manual if available..

Resistor on power supply board

Dear Biigjohn, First, first C613 means that it is a capacitor, not a resistor.And It seems to be a electrolytic Capacitor.If it has burst, then it's can will be inside. just search. the details of the Capacitor will be on it. most likely it will be a 10mfd 160V capacitor. Check and replace.
