Hello I'm faced with the problem as others. The zenith xbs444 system works for 1 to 15 minutes then does the same thing 3 blips and powers down. I've tried everything I could think of.
I've pulled the fan out and checked the board for power, but no power.
Again, there are 3 bleep noises then the TV goes to a blank screen and the system seems to reset it's self, I mean the power kinda of flashes and "power light" goes from green to red, but the clock keeps it's time.
Thank You,
I just got done repairing a Zenith XBS444 and the problem is IC706, This defective component is located on the audio output board. Part number is KIA7805A. There are 3 KIA7805A IC's in a row, first one is not on a heat sink, the two behind it are on tall heat sinks, it the 3rd one that is defective. I would advise you to replace both IC's that are on the heat sinks.
Battery needs replacing
I had the same problem make sure the cooling vents are unobstructed and that the fan is running i had to replace the fan. its a very easy procedure and can be bought at most electronic stores (radio shack)
or parts express for under 12.00
