Question about Panasonic Televison & Video

6 Answers

I have a 3 1/2 year old Panasonic TH-42PX50U TV that has recently been spontaneously clicking off usually both the video and audio. The red LED above the on/off switch will begin flickering at the same time. The remote & TV on/off switch at the same time will not operate. Eventually in 10-20 minutes the light stops flickering and both the switch and remote again function--and the TV works normally. These events definitely occur more frequently the longer we try and use the TV. If the set is unplugged for a few seconds, however, it is operational sooner. The same problem occurs if the TV is plugged directly into the wall or into a surge ;protector. Is there an economical fix for this problem--is it over-heating an electrical component-do I need a new TV? Lou

    Is this a known problem with this TV and would is it usually worthwhile pursuing a full service call? I know enough without your consultation that a tech can perform an in house circuit check, but wanted to know if this is a known fixable problem that would make economical sense..

    The sol'n was adequate, but still did not answer the question if this is a frequent problem particularly with this TV or plasmaTV's in general.

Sir,

The problem could occur if attached to a surge protector. Also open the tv and check the power supply board it may lose solder joints or connections. Check external output souces it correctly plug in or not?

thanks
good luck

Hi and welcome to FixYa,

Initially, I doubt if there are any major components defective. From all indications based on your description, possibilities are:

  • heat related issue;
  • cold solder joints;
  • leaky capacitor particularly in the power supply board, especially the +5VDC rail and the mains B+.
The repair would be low cost if you are considering a DIY (do-it-yourself) repair. However, to be able to do this, you must have some familiarity with electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY, perhaps your best bet would then be to seek the services of a qualified professional. If the cost of repairs and downtime would be factored in, then you may have to re-evaluate your options and consider a replacement.

Good luck and Thank you for using FixYa. Happy New Year.

This sounds very much like your flyback on the main board needs replaced (this controls power flow and is overheating causing your tv to shut off and on! this part should only cost around $70.00

    Thanks.


  • ronny2051 Jan 01, 2009

    no its not a general problem, Occurs because of many regions…
    1) high electricity
    2) due to some shorting on the main board
    3) or due to humidity climate(it effects the circuitry of any electrical devices).

My panasonic is not coming on,the power button is just flashing red(TH-42px50u)


Count how many times it blinks. Sometimes the problem is coded in the amount of times it blinks. If you see a distiction between blinks, say like 13 then a pause then back to 13 more blinks, google solutions for a 13 blink standby for your tv and you might be able to find the soultion.

Panasonic TH 42PX50U Red power light flashes 6 times


Most of the time when this happens it is the ysus board, that noise you heard was a capacitor popping. Another board runs about $175 and thats if you do it your self. A shop will most likely charge around 500-600, hope this helps, you could also try contacting panasonic and trying to get past the tech and onto casemanagement where you might get somewhere with an out of warranty fix.
