Panasonic PT-50LC13 Television Shuts off

My Panasonic Tv Shuts off randomly. Once it does the power button flashes red and the fans continue to run. This happened once or twice last week, but seems to be getting worse as it will not stay on for more than a couple of minutes today. Any ideas as to what the problem is? The bulb was replaced about a year ago and the tv gets minimal use.

You need to check the Inverter board of your TV. Here, I provided you the link to see how it looks like:

This is a common problem with most LCD TVs. And you need to refer also to a TV technician to test it if there's a problem with the inverter board. Then you may replace it if found defective.

Have a great day!

Hi,

It means the power management circuit has captured the system and shuts it down when turned on just as fast as possible. The fact that it does not reset is another sign of serious trouble.

However, the power management circuit is likely not the problem; it is just responding to excessive current detection from other parts of the set. Most common is a failure of the high voltage section or the horizontal and vertical deflection areas.

It will need a tech to diagnose precise section and parts that are in trouble. The cost of repairs is usually between $150 and $250 for such types of faults.

Do not despair. This is a fine set. I like Panasonic; it is one of my favorite products. It is well worth the cost of fixing it up. It SHOULD last for another 7 years, so consider it to be a small annualized expense to keep it running. You will have many years of high quality entertainmnet I am sure.

Also 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

Panasonic TV shuts off after a couple minutes


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Ballast failure is more that likley the problem. Is the lamp light blinking,...once every 5 seconds? Discontinued part and can only be purchased used or rebuilt. Rebuilt units are available, check Ebay. Have a service type person confirm problem before throwing good money after bad!

My Panasonic PT-60Dl54J tv shut itself off and the power button is now flashing red 6 times. What has happened, how do I fix it?


This is straight from the service manual (I'm not sure what the problem is but it sounds serious):

8.2. Power LED Flashing timing table
When an abnormality has occurred, the protection circuit operate and cuts the power supply. At this time, the defective line can be
identified by the number of flashes (red) of the power led indication at the front of the unit.
NUMBER OF FLASHES CIRCUIT MICRO PIN
1 LOAD SHORTAGE 92
2 OVER VOLAGE 93
3 FAN SOS 94
4 MAIN 3.3V 88
5 LAMP DISABLE 61
6 GC3FM-IIC IIC
7 GC3FS-IIC IIC
8 GC3I-IIC IIC
9 COLOR WHEEL STOP 110

It could be the ballast that is bad. A bad ballast also shortens the Lamp life .

Panasonic model# PT-50LC13


It very well could be the ballast. I unfortunately have this tv and keep extra bulbs because they go out about once a year. Last time when I replaced the bulb the tv blinked and the red lamp light flashed like it does when the bulb is bad. Ballast repair kit fixed it up. This is certainly a design issue but you'll get no help from Panasonic. If tv comes on the goes out after a while, clean the fan filter.
