My panasonic th-50pz800u won't power up. The power lights blinks 10 times then pause 10 times then blinks a again?

These blinks are fault indication. From the number of blinks occurs at one time switch on, you can get an idea about the faulty section circuit inside it.

how many times does the power light blink? Let me know and I will assist with the issue.

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

thats a sos error for numerous supply voltages missing. Send a email to me for assistance as I cant post the info here [email protected]

thats usually caused by a blown thermal fuse on the transformer and the 10 blinks appears. I can assist but will need to do it via email you can contact me at [email protected]

plug it in

Power board it dead,take the tv aparts.Check for Capacitors parts for puff up or burst open.Know how to solders?replaced these capacitors in the power board.Or replaced the whole power board.Tries Shopjimmy.com,Ebay.com.

There are two guides, one for 10 blinks at power on:


or, 10 blinks at plug in:

if you have a warranty let them check it out before opening the panels, it may void it.... may be an internal power short.

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.
