Panasonic Viera TH-42PX80U Plasma TV - Page 5 - Answered Questions & Fixed issues

in menu speakers switched on or off?if you put your ear to the speaker do you hear anything?Is set connected to box of some kind for audio and video signal?

YOU MAY WANT TO CHECK YOUR HDMI TO MAKE SURE IT IS PICKING UP YOUR CABLE SIGNAL. TO KNOW MORE, IS THE SCREEN DARK, LIKE OFF, OR WHITE SCREEN WITH LIGHT...IT VARIES...OR DAMAGED PIXELS.. TO GET A SPECIFIC PROBLEM SOLUTION YOU CAN GET AT WWW.BESTDIRECTORYSOLUTIONS.COM

CAPACITORS ARE THE MOST COMMON PROBLEMS WITH PANASONIC POWER SUPPLIES. THESE CAPACITORS EITHER BLOW UP ,CRACK OR BULGE ON THE TOP... IF YOU SEE ANY OF THESE REPLACE THEM... YOU CAN PUT A LITTLE HIGHER VOLTAGE TO KEEP THEM FROM FAILING BUT DO NOT CHANGE THEIR VALUETHIS IS THE CAUSE FOR NO PICTURE ONLY A BLINKING LIGHT ON YOUR TV BUT NOTHING ELSE.

Hello,The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.All these can be checked on the power supply board.But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.I hope this helps.Good luck

Simply plug the yellow, white and red plugs into the INPUT 3 ports on the front bottom of your TV. Use your TV/Video button (either on the remote or next to the INPUT3 ports) and select scroll to the Video3 option. Ensure that the 3 plugs are firmly pushed into the ports. My initial problem occurred because I thought they were pushed in all the way, but they weren't. You do not need to have your tv on any specific channel for this to work.

Hello:First check you audio setup in your user menu. You may have the audio in SAP mode instead of Stero.

Hope i helped you.


Thanks for using ' Fixya ' and have a nice day!!

you probably have a tv decoder cable or satellite witch also has a aspect converter

Hi,

Please unplug the unit from the outlet for 15 min and then plug it back in and check if the symptoms still the same. Also, does the symptoms appear in all inputs?

Check if you don´t put by mistake the sleep function

Hello, not sure what exactly you need for your fix. But, I have used a company named ShopJimmy.com in the past with great success. I included a link to the page on their site with all of the parts for your model. Hope that helps!

Let me ask you this is the Model number on back of your TV TH42PX80U ?

The grey bars signal that the source image is originally in 4:3 format - if you are using a box of some kind get in its menu and change the format from there to 16:9. The black bars appear when a 16:9 image is sent to a 4:3 format in Letterbox mode - leave it like that or the Pan and Scan mode will chop the sides.

Hi, You should have unplugged your set in a storm like that. You should have had a surge protector too. I believe you will be looking at a big repair bill. Good luck.

hi,
In your tv there some problem with power supply. you have to check the followin voltages. Sub 5v SOS ,Main 3.3v SOS A-Board,DTV 9v SOS , Tuner Power SOS. If any one of the voltage fails it will shows 10 blinks.
ok

You can easily do that yourself. Just leave the tv unplugged overnight and then get it open...find the A board and just take out screws and then replace with the new board. Super easy!



Thank you and best of luck!

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

Hello and yes there is a easy way to solve this issue, on your Panasonic remote go to options or menu, in your memory list there should be a selection called either factory reset or default settings, choose it and hit OK, this will set your tv back to its original out of the box state.
