I work for a company that is factory authorized for 20+ manufactures I am sorry but a didn't see your brand and model # if I can get that I can research it for your and see what may be your problem. Sounds like something is blowing your bulb or they are not putting the correct value/wattage bulb in when changed. Let me know

If you have a voltage meter you can pull the bulb out and check for continuity by placing the probes on the power plugs of the bulb. If you have continuity the bulb should be good, and it may be the lamp ballast.

Its the fan that cools the bulb. Try turning on the tv and look at the fan to the rear of the bulb. If the fan is not spinning that is your prblem. The tv has a safety switch that will cut off the tv if the bulb gets too hot. I was able to tap my fan with a pencil and get it spinning, but that is just a temperary fix. After a while, you will find the fan will stop working all together and it will need to be replaced.

Buzzing sound, resets 8 times, and then turns off. Bulb replaced


Actually ballasts run between 60-80 dlls. It does sound like you doi have a ballast issue, everytime a TV resets the ballast is the issue. Go to discountdashmerchantdotcom you'll see the ballast prices. Plus they also have free troublehsoot.

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.

T.V will automatically turn on and off during the first 10 minute


With projection TV's the lamp is usually the cause for cycling issues. The lamp power supply (ballast) monitors the current drawn by the lamp and adjusts voltage to keep the current at a specific value, if the ratings fall outside of spec the TV will cycle power and attempt to correct the anomolie. If this happens too many times within a specific time frame the TV can refuse to turn on and will indicate an error code. Don't put the TV through too many retrys or you could damage the ballast too.

Lamps can cost between $200 and $400. The ballast can cost anywhere from $150 to $250 approximately. Usually the manufacturer of the TV will sell you a new bulb, but electronics suppliers often sell them for less. Most lamps are owner replaceable and easy to do, consult your owners manual.

In-home servicers can base their labor charge on the size of the TV. The larger the TV, the higher the labor cost. Do it yourself and save!

Hope this helps.

PT 50LC13-50 Panasonic TV


Going through bulbs that quickly would indicate to me a problem with the ballast or smps (switch mode power supply). It's not something you want to just run out and replace (expensive).. Call a reputable shop and tell them what you're experiencing.
I do know that they should check the value of C1330 in ballast circuit. If it is a .22uf, There is an upgrade kit available for it, panasonic p/n# LSUC0022
