Question about Akai PT4298HD Rear Projection Television
WHEN I TURN MY TV ON THE TIMER LIGHT JUST STARTS BLINKING WERE CAN I GET THE PARTS TO FIX IT AND WITCH BORRD IS IT
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
