Re: 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

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

It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

The 3 times LED code points to no fan rotation. There are 2 fans. Check the larger fan first, p/n = FBL12G12LS, located near the lamp. Even though that fan may be rotating, it may be slow.
