After 15 minutes tv turned on screen goes funny

Hi,

Please remove the batteries from your tv remote and then turn on the tv directly from the tv itself. If it stays on that means that your remote had an iffy power button that was the source of the tv constantly being turned off and on. Thank you.

Hi rosscop

You have a magnetic interference problem. First, have you put any magnetic objects like speakers near the set recently. They will cause this. Turn the set off at the wall and wait for 15 mins for the PTC device that turns on the degauss coil to cool and operate. It is the loud burst of hum you here when you turn the set on from cold.

The PTC is a postive tempeture coefficient that allows alot of current to flow at first, heating up as it does, and then slowly less current as it heats. This is why you need to turn the set off and let it cool. If the problem remains The PTC may be faulty allowing too much current to flow and upsetting the magnetic flux about the tube. If you dont have the skills you will need a technician to sort it out for you.

Go into Pictures Settings and look for settings to turn the right way. Then look for Rest Picture Settings. In reality, you probably need a new set or a service centre for the funny colours.

Hello !! first of all check for bad connection on the led strips if all connection ok , test the single led one by one , at the end Do not Hesitate replace the leds strips . Because problem could happen after heating .

H00 is code showing the system has no memory of an error so you could try turning the power off for 15 minutes then back on and see how it goes. Power supply fluctuations can sometimes make Panasonic A/C's do funny things. If the fault recurs, you will have to get a tech to diagnose.

Hi, this sounds like your TV needs De-Gaussing, the screen has become magnetised and the electrons being fired at the screen are being diverted or scattered and mixed to the area's that are magnetised creating the odd colours, what you need is a de-gaussing coil, you can wave this in a pattern to de-magnetise the screen thus allowing the electrons to flow properly to the screen, it may also be the PTC on the tv's PCB near the mains input, if this is faulty the tv's own degaussing coil may not operate properly, you local TV technician maybe able to help with this as the part is specific to the TV, they maybe able to degauss it too for a small fee.

Here's a better expaliation ---> CLICK HERE <---- it shows a circular pattern here but there are many kinds of pattern magnetism can create but the colours are nearly always the same just in different places witn different strengths.

Hope this helps.

Ur backlight video board it,dying.Micro processor have shorted,must change the backlight board.

The projector is starting to go out in it. Depending on your financial situation, you can take it to a shop to have it looked at, or replace the TV. Depending on how long this has been happening, the Pioneer projectors usually last about 100 hours once this happens before they burn out completely.

it seams that your tv is high heated or it is needed to change some of the tranzistors... as it seams the damage isnt realy bad..but it need an "experts hand" to be fixed
