Question about Televison & Video

1 Answer

Panasonic TH-42PX60U has a series of relay clicks and then turns on and off by itself. I have replaced the power supply. This did not solve the problem. Fuses are not blown because powers on and off. There are no series of blinking lights to indicate an error code. Source of problem and solutions?

Your most likely going to have to have a technician come by and look at it the blinking helps for finding the error but is not necessary however replacement will require schematics and soldering which I would suggest not doing yourself if the tv is still under warranty I would suggest returning it for a new one before investing anymore money into it


hope this helps

The panasonic th-14v3 doesn't power on


These sets are known for bad power supplies. Try to google the model # and price for power supply and you'll have a good idea of the repair cost. Most reputable shops would charge 195-325 us dollars but this is just an experienced guess. Good luck, Russmann.

the power supply on the unit has failed. it is possible to replace these yourself but if you do not know what you are doing then you could cause more damage. you are probably looking at about 150-250 dollars for a new power supply, if it is still available.

TH-42PX60U wont turn on. Blinks 10 times. replaced the power supply board, but the same issue.


What I'm learning is there are several models of Panasonic TV's that have a video card that doesn't play well with HDMI applications and the end result is, you need to call this number and not only make arrangements to replace the bad board,but also this!
Your model doesn't show below,but I'd certinly inquire about the necessity of a "Firmware" update!,,,Panasonic knows FULL WELL they have a HUGE problem here!
Hope this helps!

At panasonic.ca I found the listing for the fw update under customer support-important notices

Panasonic plasma hdtv will not power on--no blinking LED, simply no LED. Other objects plugged into same surge protector are fine; no evidence or suggestion of a power surge.


The power supply board itself maybe the main problem inside the TV. Or, it maybe something simple like a blown fuse. Replacement fuses can be found at Radio Shack or some other electronic supply store.
If it turns out the TV keeps blowing fuses, the main power supply may need to be replaced. You can find replacements at a good price at Shopjimmy.com

TH-42PX60U red light blinks 10 times wont come on


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.
