The screen in black, but I get sound. Just replaced the bulb about 5 months ago. There is a green light that flashes, but not the red light. a couple of seconds after turning on the TV, I could hear...


Outside of the lamp failing, the main exhaust fan on the Left side facing the back of the set is common to fail, the set shuts down. But when this happen it always causes the red led on the front of the set to blink a code. If the green led continues to blink, I would inspect the lamp, if appears to be ok, reinstall it making sure that the inner door latch for the lamp is secure and tight.
When looking at the lamp, pay attention to the the bottom of the lamp stem where the bubble is. If you see a discolored, bulged out area on the bubble, the lamp is bad. I have seen this happen even on new lamps from Sony.
I hope this helps,

Have green spot on left third of picture.


is it an LCD rear projection? Then it is the light engine. Confirm it with a tech visit and then buy another set. The light engine costs as much as a new set.

When turned on green light flashes and no picture


Check the Lamp if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 2X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.
Check the ballast if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 3X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.

Panasonic PT50LC14 Power issue


We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.

Turns on and off green LED flashes until TV turns back on.


this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.

Blinking green reset light


Can you please supply us with the make and model as well as the blink count of the green light. That count should be indicating the problem circuit. Once that info is posted, we should be able to give you more details and possible solutions.
