Question about Akai PT4298HD Rear Projection Television
I have a problem with my 52" akai tv turning off and on. I turn it on then a little while later it turns off can you help with the problem
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 a comparable SamsungModel, buy the Samsung comparable Convergence boardfor $77. It came to about $85 after shipping. Call them if you need the exact model #. The Convergence board hastwo 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 boardin the TV. It is basically a complete system that takes less than 30minutes 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 allthe screws for the screen, as it is unnecessary, and might just damageyour screen if you are not careful.) It has a u-like shape and comesoff easy. Detach the gray wires connecting your old board to the restof the circuitry, and detach the blue wires connecting the old board tothe circuitry. On the old board, there are connectors marked, fromleft, blue, green and red. Detach those from the old board, and markthe 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.
