Question about Akai PDP4294 42 in. EDTV-Ready Plasma Television

1 Answer

My Plaxma flat screen, AKAI PDP4294 is dead

When i turned it on this morning, i was immediately greeted by a loud noise and then a pop, followed by a shower of sparks! I pulled the plug but it was all done by the time I got the plug out. Being curious and a strong doityourselfer, I pulled the back cover off for a closer look. I found a char mark on the back cover which helped me zero in on IC2, in the power supply area. IC2 had blown itself apart, taking any numbers it may have had with it. I bet I could solder in a new one if I had it in hand. I believe the IC has seven solder points, maybe six. Are flying sparks, and the associated fire hazzard, a common thing for these high current plazma displays? This would be reason enough to junk this thing and go to LCD!

Nontheless, I am looking for help in identifying IC2 and a source for a replacement.

thanks, Jim in Phoenix

    Now a few days later, I have found a 26 page service manual on line and was able to identify IC2 as ICE2P280, an 8 pin IC, 6 of which are used in this application. Googling this part number, I came up with a 20 page data sheet on said chip. More info than I need, as they say. Integrated Circuit Engineering (ICE) has been sold at least once, and the data sheet which still carries the ICE part number, is published by Infineon. The chip is listed in a few wholesaler's catalogs but mininum purchases of $200, or so, made the chip somewhat exclusive.



    Yesterday I found Guessepi on Ebay, who has two power supply boards for the PDP 4294 currently for sale. At a reasonable price, I might add. In his text, he also indicated a willingness to help with individual repairs. I am currenly awaiting his shipment of the specific ICE2A280 chip, which he has pulled out of his proverbial sleeve! I will update this report when I get the chip installed and see if it was the cause or part of the effect of some other failure.

    I see that people re stil reading this FIXYA problem and I feel like an update is appropriate: First of all, AKAI

    AKAI NEVER acknowledged my complaint, probably not wishing to acknowledge that sparks flew, and their product was a potential fire hazzard! what I wanted to post is that i spent my own money and bought a used power supply board which DID restore the TV, but did not change the fact that the same failure could occur again! The set worked another 2 years, and I added a 6 inch cooling fan to keep the power supply board cooler. Then the picture faded away and, allong with the heavy burn in pattern on both sides, I deemed it junk.

Well, I will tell you Jim that plasma flat screens as a whole are having similar problems without regard to brand or model. Part of this problem with others has been the poor quiet fan cooling setup they have in them to say the least. The problem you have experienced is in the voltage regulator section of your power supply. Without being able to see exactly the section the IC2 is in I would have to look at a good schematic to find the right part # for. However, through my experience oveer the years I usually go ahead and desolder the part and take it to a large electronic supply house and they are usually more often than not able to identify the component for you without a schematic. However as you said and you are correct in thinking that the plasma tv you have may give you a similar problem in the future without any added cooling fans on the back cover. Do not be deceived though because LCDs over 32" and above suffer similar problems with the added one that they have images that actually burn-in to the screen much like computer monitors and that is annoying as well. Even if your tv is more than 2 years old and past the warranty period, you may be successful in getting it replaced with a new one because you have a very common problem occuring here that I know the manufacturer knows about. Most plasmas are rate to have 60,000 hours of use which is 20 years, they just have not developed or been around long enough to substantiate that claim. Good luck and God bless.

    It is very difficult to find individual components for plasmas or lcds at this time. I have to commend you for your tenacious enthusiasm to find it on the internet. It is my opinion much easier to find the entire board than the component at this time judging from the state of affairs. I am sure that you asked him that the part would be of new condition and not used and cleaned up in some manner and of course with some guarantee to go with it. Let me know. God bless and I am glad you found a source for the part.

Dead set, Akai 42" Plasma PDP4294, no power


Porblem solved,
It's a wonderful day.... Ahhhh, it is now FIXED and working great. I found cracked solder joints on a few of the switching power transistors and some of the big diodes and other heat producing parts. Also notice that the infamous Red caps C524 and C523 were discolored but they checked OK on my cap meter and also my ohm meter, however while I was inside the set after removing 1 million scews I decided to replace them anyway.
I hope that my repair success helps someone.

No picture


The high voltage power supply for the plasma display has failed. It may or may not be on a separate board that could be replaced the owner.
