Question about Panasonic TH-50PX60U 50 in. Plasma HDTV

1 Answer

TV Won't Turn On

I've had the set for about 2 months, with no problems, and today I tried to turn it on and all I got was a red blinking light. I unplugged it and replugged it in, then tried to turn it back on. I heard it sound as if it was 'trying' to turn on and the screen got slightly brighter before it got dark again and the light returned to blinking. Any help would be appreciated, the manual is useless!

    I used my on-off switch to turn the TV off and now I can't turn it on. It goes through the start-up noises, but never turns on.

    I have a 50inch panasonic plasma tv that automaticaly turns itself off and after 5mins will click and turn itself back on but when it turns off you cant turn it on manually. I have a service call in. The repairman ordered a part. Good thing we bought the warranty. This started 2weeks after the 1year warranty expired.

    Same problem. Set is 13 months old. Worked fine until yesterday. Now it will not respond to the remote or to the controls on the front panel. Panasonic's "Concierge Service" says its a firmware problem and says they will send me the necessary fix. Hope so, since the warranty was for 12 months.

My phillips 42" is the same way. Just started popping up the settings menu the other day and wouldn't stop popping up until I downloaded the software upgrade from the Phillips web site. But now, two days later it won't do anything but give that same annoying red blinking light. The customer service says to take it to an authorized repair center. sounds like they have a ton of these calls everyday. The solution is to buy it from Costco, and make sure you return it and get a new one before their return policy expires.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...

This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.

Let me know if you have questions and try disconnection of the front keyboard FIRST.

The red "on" light is blinking and the TV

a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

I have a Panasonic PT50LC13 Television. For about the last month when you tried to turn it on, it would come on then quickly turn back off and you could hear the fan running then the red light would blink....

For that model, there is a ballast kit that would need to be installed. A diode and 2 caps need to be replace on the ballast. Check the lamp as well.

Tv turns on then off after a few seconds. No picture or sound in these few seconds.

Try this and let me know what you find:

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.

Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem

******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.



let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

if this has helped you rate this solution as I do this here for free.

Left tv unplugged for a few months no tv won't turn on

The first thing to do is try to turn on the set with the remote and then when it doesn't respond go to the set and hold down the MENU and INPUT buttons at the same time until the power LED starts blinking a two sequence code. Like 2 - 4 or 1 - 2. The code will keep blinking for five or six times and stop. The blinking is the microprocessor telling you why the set is not working. We techs call that a self diagnostic function. Which this set has. Just repost your findings.

TV Won't Turn On

Are you from US or Canada? I'm Panasonic authorized and allways Pana covered the warranty after 1 month from the expire date. Call Panasonic Viera service and tell them the story. I'm sure you'll get refound.
Anyway, a horizontal line doesn't mean the PDP is defective. It's one scan IC burned on the SU or SD board (depend where the line is). We allways replaced the SC bord each time SU or SD got burned. If after SD and SC replacement it still defective...yes the PDP has one scan line in short.
Call Viera and insist to get warranty. Let me know. Good luck!
