Panasonic PT-50L14 50 lamp has no obvious defect

No picture or sound blinks green then red. Bulb has no defects to the untrained eye. Is this still the most likely problem?

Re: Panasonic PT-50L14 50 lamp has no obvious defect

My first step would be to check the owners manual under troubleshooting for the lamp code for blinks green then red. I suspect the problem is in either the ballast that drives the bulb, or the bulb (P/N TY-LA1000) itself - you can't usually tell a bad one from a good one by looking at it. The ballast is difficult to replace, and I would call in a repairman to fix it if a new bulb didn't do the trick.

Power button blinks green about 1 minute then goes red

There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

When you trun on my panasonic PT-61LCX65 tv it makes no sounds the light blinks green. and then red and turns off. what is wrong. i have looked at the buble and it looks fine.


does the TV bring out sound even as the screen display is dark?

How long have you been using this TV and have you ever changed the lamp/bulb? Problem should be from the TV lamp/bulb.
Have the lamp replaced and hopefully, your screen should be perfect as before.

Let me know if you need directions in replacing the lamp, even though it is very simple replace.

Yours sincerely.
