Question about Televison & Video

1 Answer

I have a Panasonic PT-50LC13. Replaced the lamp and then the complete Ballast box. now when I turn on the television it comes on for about 10 seconds then shuts off and the red light blinks indefinitely about 1blink/sec. Have to unplug the set to get the light to stop blinking. Any ideas what may be wrong?

This set should not even be around, there was as you may or may not know a massive recall and in the USA all were supposed to be exchanged. I know as we were involved in picking dozens up and sending them back to Panasonic, they did not care if we removed parts etc as they were junking all of them.

many were actually working with no issues.

As to your problem: a constant blink is a real short somewhere, usually a blink sequence.

what was it doing before lamp and then ballast were replaced?

    would work for a short time then go off and blink the code for the ballast. Do you know if they could still be replaced?

    No, that was over at least 3 years ago.---so since the lamp and ballast were replaced you have a different issue----Ballast came from Panasonic?

With any lamp television, you should try the lamp first, as it is the most likely to go. If the lamp is cloudy then it most likely is bad.

When the TV is turned on the turns off about 10-15 seconds later. The bulb was replaced a few months ago.


There was a recall for this TV's ballast. You need to rebuild the current ballast and may possibly have to order a new lamp.

Panasonic pt-50lc13 it just will not turn on,but the red light is on and the lamp was replace


Is the lamp indicator light flashing? A new lamp may not solve the problem. The known problem with lamp failures is poor voltage output from the ballast,.. a problem Panasonic refuses to correct and they decided to no longer provide the repair part through their supplier in an attempt to sweep this problem under the rug.
Lamp light flashing once every 5 seconds or twice every 5? Twice every 5 seconds,....lamp failure, once every 5 seconds,...ballast or thermal fuse failure. You have a lamp, ballast or thermal fuse problem. The ballasts are a discontinued part and can only be purchased used at approx. $225.00 or rebuilt for around $175.00 less any service charges to diagnois and repair.

Panason PT-50LC13 TV won't come on, light blinks green then red


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!

PT-50LC13 Lamp issue


i hope the lamp was panasonic or bought in a good place (average cost of this lamp is 250 dllrs)
if the lamp is trustfully. i would put attention in the back side when you listen the arcing that the lamp at least try flashing.

This moment of the repair where you are is critical because you arrive to conclusions according to the process you already did and suspect that what it is already done is fine (but is really true that lamp works plus is really true that the arcing is because the arcing devise arcs or is only the primary of the transformers in the ballast who holds 300 volts in the primary (really good voltage to make arcing sound too)
Now the error code is going to be 50 % good or not: i mean or gives you the error of the ballast and lamp or any voltage is missed in the power supply ( i don't have the error codes chart for you with me) because i would like to go far and the problem was in the same place where i started/
