SOURCE: Set will not come on; timer light only

ok you have fault oscillation inside and you have defective parts! the problem is power oscillation! the trouble is in the power section (hot and cold) or the jungle IC circuit.

I contacted partstore.com. they were able to give me a part # for the board that you need. it was around $120. your problem may be more extensive than this though. was there any other service done to the set prior to this happening?

SOURCE: won't turn on

Only way I've found to fix (temporally) this is to unplug and plug the power plug into the wall socket...... sometimes it takes a few tries but it does work. I had a few tv techs come out and look at it. One wanted 400 bucks to fix it and told me he couldn't guarantee the work or the part if it had the same problem again. Hate to get rid of it I paid about a grand for it back in 2002/2003 and bought a home entertainment system with it

SOURCE: AKAI MODEL#PT4298HDX/SMS RED TIMER LIGHT JUST KEEPS BLINKING

Do not panic! Do not throw your TV away like I wanted to! Here is whatmay be the solution for most of the members who have posted theircomplaints here recently. I am not an expert, but I followed all blogsfrom various websites and forums, and the conclusion was the same;replace the convergence board for this model. I purchased it fromwww.partstore.com and since this Akai is the same model as the SamsungModel # HCN4226WX/XAA, buy the Samsung BP95-00142E Convergence boardfor $77. It came to about $85 after shipping. The Convergence board hastwo black STK ICs and two colors of wires, a gray kind and a bluekind, all which have 'pins' and can easily be unplugged from thecircuit board in the TV. It is basically a complete system that takesless than 30 minutes to install. It is a simple swap procedure, with nosoldering. You only need the new board and a screwdriver! Remove thelower back board of your TV where the cables are plugged in (do notunscrew all the screws for the screen, as it is unnecessary, and mightjust damage your screen if you are not careful.) It has a u-like shapeand comes off easy. Detach the gray wires connecting your old board tothe rest of the circuitry, and detach the blue wires connecting the oldboard to the circuitry. On the old board, there are connectors marked,from left, blue, green and red. Detach those from the old board, andmark the wires so that you may connect the correct the wires to the newboard. You then unscrew the only screw connecting the board to the TV,and unhook the board from the TV. Hook the new board to the hooks whichheld the old board, and screw the lone screw to the board. Plug thegray cables from the new board to the connectors where the gray cablesfrom the old board were,and do so for the blue cables. Connect themulticolored cables to the blue, green and red, just as was done on theold board. Reattach the cover and test the TV. Please do not replacethe two STK ICs only. When I removed my old board, I realized thatthere was a burn mark, where the ICs were, but maybe it was a fuse. Youmay replace the ICs only to discover that it was another problem. Goodluck, and I wish you all the best in the repairs. I just saved about$100 for a repairman just to show up

TV won't turn on


It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

I have a akai pt 5492 and the timer light is on how do I get it to turn off and the tv to turn on?


If all you have is the timer light the set is in shutdown because something is wrong, most common issue is a short in the convergence circuit.

Even with Akai name set was made by Samsung.

A few simple tests are needed: what is your skill level with electronics?

Only the red light comes on


Whats up Wade?

This is DVD MIKE with Perfectimagess.Try this first .Unplug the TV for a while and press the On/Off button which is supposed to perform a "reset".After that, plug the TV back in. It should come on and the Timer light off. The picture and colors might be distorted, but pressing the Perfect Focus button on the remote control resolves this right away.

The problems is a black picture or the TV won't turn on. The Timer light stays lit even though no Timer has ever been set. The colors converge and the picture is pinched. I don't think all of the expensive repairs are necessary, My TV did go out after a week of non-use while out of town (I was out of town, not the TV). I don't know. I'll post more if I learn more. I hope this helps Wade,

Vacuum the dust off of the circuit boards and inside the cavity. TAKE CLOSE UP PICTURES OF THE CONNECTORS BEFORE DISCONNECTING FROM THE CIRCUIT BOARDS. (IF YOU HAVE TO.) TAKE OUT CIRCUIT BOARD MOUNTING SCREWS. AND REMOVE THE BOARDS.

VACUUM THE DUST. LOOK- SMELL AND CLEAN THE GROUNDS, AND CAREFULLY CLEAN THE BOARDS. ASSEMBLE. DOUBLE CHECK CONNECTIONS WITH PHOTOS,
AND PLUG IN, TURN ON AND HOPEFULLY ITS ALL GOOD.

WADE WORK WITH ONE HAND AS MUCH AS POSSIBLE SON!!

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

Akai PT4298HD problemo


I'm not a repair guy, just happen to have one of these TV's. Seems to me that unplugging the Convergence Board removes it from the equation and suggests something else might be the problem. I got most of my help from here and also from this thread:

http://www.tv-forums.com/forum/TV_Equipment_C4/Projection_TV_Forum_F24/Samsung_42_Convergence_problem_P4569/

The samsung TV is the same TV as this Akai, it's just a rebadged Samsung.

One important difference in my TV from yours. I did have a timer light, and with the back off, I could hear it power up when I plugged it in and turned it on. The timer light would flash then it would go off.

When I removed the convergence board, I could clearly see burn marks on the bottom of the board where one of the amps was soldered on. That gave me some piece of mind in ordering the part. I just scanned that other thread but remember some people talking about the power supply failing as well as the main board, you might pursue those avenues.

I wish you luck in fixing this!
