AKAI 55" Rear Projection TV won't turn on.

Hi! I have a 3-year old AKAI 55" rear projection TV, Model #PT5598HDX/SMS. I love it! Two days ago, I had the cable company send me the box and turn on HD. The same day they activated the HD through my cable, I turned on the set and the picture appeared distorted similar to a 3D movie without the benefit of the special glasses. I thought it was because I hadn't hooked up the converter box yet and got busy doing so. Once everything was hooked up, my TV no longer turned on. I had power to the converter box and the TV's little red timer light would flash several times indicating that it had power but no picture, no sound, no anything. I tried not only with the remote but also at the set itself using the power button.
I've been looking at LEDs and Plasmas, so this is a good excuse for upgrading but it is driving me crazy not knowing if it is something simple that could be fixed or knowing whether or not switching to HD had anything to do with it.

I mentioned it to a friend who wants the set but I'd like to be able to give her some kind of idea what it might take to fix it or even if it is worth the trouble. Thanks!

The convergence will destoted the pic but has nothing to do with the tv comming on do you have a green light flashing were your remote eye is on the front of your tv ? if not then see if cleaning the remote eye on your tv set with a air hose or air in can or if you can reach it us a cloth to clean the eye. if the eye is dirty sometimes it will not let the tv come on. it happened to me. and if the tv did not have problems before you hooked up the cable box then unhook it and try playing a dvd through it that is if you can get it to turn back on to see if the picture clears up

Just a thaught, I could be wrong, maybe a problem with the power button on the remote ? It might shut the TV off, and when you do keep pressing the remote button, the red light on the TV will keep flashing like that also. Ive seen this prob on a few other blogs, so seems to be pretty common. I know I like to keep the remote pointed at the TV all the time, maybe try pointing it away for a while, just to see.

Do not panic! Do not throw your TV away like I wanted to! Here is what may be the solution for most of the members who have posted their complaints here recently. I am not an expert, but I followed all blogs from various websites and forums, and the conclusion was the same;replace the convergence board for this model. I purchased it from www.partstore.com and since this Akai is the same model asa comparable Samsung Model, buy the Samsung comparable Convergence board for $77. It came to about $85 after shipping. Call them if you need the exact model #. The Convergence board has two black STK ICs and two colors of wires, a gray kind and a blue kind,all which have 'pins' and can easily be unplugged from the circuit board in the TV. It is basically a complete system that takes less than 30 minutes to install. It is a simple swap procedure, with no soldering.You only need the new board and a screwdriver! Remove the lower backboard of your TV where the cables are plugged in (do not unscrew all the screws for the screen, as it is unnecessary, and might just damage your screen if you are not careful.) It has a u-like shape and comes off easy.Detach the gray wires connecting your old board to the rest of the circuitry, and detach the blue wires connecting the old board to the circuitry. On the old board, there are connectors marked,from left,blue, green and red. Detach those from the old board, and mark the wires so that you may connect the correct the wires to the new board. 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 which held the old board, and screw the lone screw to the board. Plug the gray cables from the new board to the connectors where the gray cables from the old board were,and do so for the blue cables. Connect the multicolored cables to the blue, green and red, just as was done on the old board. Reattach the cover and test the TV. Please do not replace the two STK ICs only. When I removed my old board, I realized that there was a burn mark, where the ICs were, but maybe it was a fuse.You may replace the ICs only to discover that it was another problem.Good luck, and I wish you all the best in the repairs. I just saved about$100 for a repairman just to show up.

Akai PT50DL24 50 in DLP Rear Projection TV-NO PIC OR SOUND


check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.
