Panny TH-42PZ80U Plasma TV No display on Power-up

Panny TH-42PZ80U Plasma TV
Initial power up produces a relay "click" and then the backlight or display seems to want to come on for 1 second, then black screen. Front Power LED DOES not blink any service codes... but rather stays illuminated like normal. P/S issue or worse??(Have checked all fuses on P/S board LC1709-4001DC)

I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!

Panasonic th-42pz80u...dead set...red LED blinks twice at turn-on...the 15v supply on pin 1 of P7 comes up for a second then shuts down


I'm no expert but I have the same tv I'm trying to fix,different problem from yours.I think you can take a resistance reading from that pin to ground and if there is a short,you can start unplugging different boards and when you have the right one the short will go away,if not its the power supply.Put in a search on google with something like board layout for TH-42PZ80U and click on the link 11th generation and you can tell if I told you right or not

Hi Is it possible for you, send to me the part number of power supply of my Panasonic TV #TH-42PZ80U?


Hi,
You may view the part no. at this LINK. It is advisable to get the actual part no. listed on the power supply board itself because there some version made by the manufacturer.
Hope I helped you.

Trying to find out what parts needed to fix panasonic th-42pz80u


If your TV model is TH-42PZ80U, and you want to replace the whole power supply unit, shopjimmy.com has them for $160. But for each parts# on that board itself, you need to find a Service Manual to look up that part.
