Panasonic PT47WX53G rear projection tv shuts off on its own within a minute and led indicator flashes 3 times?
The TV has the three colored lamps and is not led. I have had the tv for about 4.5 years. This problem just arose and did not occur over time. It does not have a “lamp module” as some of the newer tv sets do. At least I don’t think it does. I can’t find a part number for one if it does. Is it worth it to fix? In home repair is 80 bucks just to look at it. Any help would be appreciated.

The TV goes off but comes back on
this means the horizontal safety circuit
usually responsible for shut downs
is not at fault
if the horiz safety trips you have to unplug the TV
to reset the shutdon status
I would start by verifying your TV is plugged directly
into a wall plug
no extention cords and no surge protectors
If plugging into the wall stops the shutdowns then
go out and replace what ever cord you were using
otherwise you need a TV tech to look at the TV
the problem could be in many places in the TV
convergence IC may be failing
135 volt supply to the horizontal sweep could be low
almost any low voltage supply could have a cracked
solder connection causing random interuption
also I recall nuisence shutdowns with that Model
from the CPU PCB being loose
Left side of chassis all the way to front of PCB
its a small PCB that docks into signal main PCB
and it has 3 plugs that fit into sockets and it does
get loose over time (heating and cooling)
What I would do would be unplug the TV
then remove and remount the CPU PCB
it was that simple
But that 80 dollars does apply to the repair if you authorize the repair….
The model number tells me the MOST LIKELY problem is the convergence amps since it takes almost a minute to shut down, but…..
It might be your vertical or horizontal circuit…those initiate a 3 blink failure code too….
So I would suspect the convergence amps may cost about $380 for those or $320 for vertical /horizontal repairs…..
If you can afford those repair costs, it’s worthwhile to get the TV tech out to your home…
IF NOT, set it outside and tag it with “IT works — Need Fixed”
It’ll be gone in no time….
