My Akai PT5598HD is 4 years old. The set will not turn on. There's no picture or sound, just a blinking red timer light. Do you have any suggestions? Do you have instructions where part is located in TV and how to replace?

On the power supply board is a tyrisitor and high voltage capacitors 2k most of the time Poor Solder Connection right where AC line connects,you will see it on that board.
Resolder everything and set should come on.
on the main board of the tv there is a fuse located if that is faulty this can happen,there are also many other possibilities but check out the fuse first many a times replacing the fuse solves the problem
as its very negligible to replace the fuse the cost of fuse is under $1.
sounds like your convergance ic's shorted on you. you can replace the fuse in the power supply and disconnect the conv board and see if it comes on. if so order new ic's and check all resisters for the correct values. good luck
If you're using a DVD player or other component using the Component cable hookup, try unplugging that from the mix, unplug the power cord for the TV from the wall and wait 15 seconds and plug it back in, then power the TV back on. Mine used to do this and I gave up on the component cable option and went back to composite (RCA).
I talked to an Akai certified tech who told me the problem is a bad convergence module. The part alone is $400. Fortunately, I purchased mine from Costco 3 years ago. Costco has a 100% guarantee policy that I was not aware of. I called them asking if I had an extended warrenty and they gave me the full purchase price as a refund ! If any Costco purchasers are experiencing this problem and you purchased the TV prior to March 2007 (when Costco changed their policy), you may be able to take it back and get the full amount you paid for it. I turned around and purchased a new, larger Panasonic for under $150 more. It has a 5 year warrenty.
