stephenbirdwell826 what exact model is your TV? Just to clarify, you have no sound and no picture? The only thing that works is the power LED and it is red?

da

my is no pic no sound no light

da

had the same problem! Great Pana tv and all of a sudden screen went black, no sound, nothing. the only thing i am able to do is unplug and replug and then the red light comes on and blinks then is solid. I can not turn it of with the remote or by the tv remote, i have to unplug manually.

How do i get to that engineers screen or whatever you guys are talking about. I cant afford a new tv either. or a repair man. I do follow directions really well though.

i tried the unplug, press power button process and nothing.

stephenbirdwell826 , First try unplugging TV for 20 min's and press and hold power button on TV for 10 sec's to reset and plug TV in and try. If no go remove the back from TV and remove plugs/ cables reseat them to make sure all have good connection and try TV again. At any time if you start getting light blink codes, use the 2nd link to diagnose the fault.

Could be possible power supply board issue, remove the back off of TV and look for any evidence of a power surge, bulged capacitor, hot/burn marks, etc., replace parts on the board or replace board found with defective parts. Check out the 1st link below for more info. on diagnosing a TV with this type of issue. If not comfortable working on the TV, have a good local TV repairman have a look, diagnose and estimate repair. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

Basically all you want to do is go over to the TV power button that's on the TV and after turning it off using the button turn it back on but instead of releasing hold down that button after about thirty seconds the TV should turn back on again this is only if you're having the same problem as me which is where your TV has gone black but your power light is green and flickering or just staying solid otherwise I guess try the other methods that have been given to you but other people on this website

If you're having trouble finding the on and off switch on the TV go to the bottom middle of the TV and it should be there if not try the edges of the said TV

da

It worked for about a minute then went off again

da

didnt work for me

da

Didn’t work for me. The last time it had done this I unplugged tv and the cable box. Waited 30mins then plugged them in. Tv then had came on. I did notice after pushing button if the screen turns blue around the outsides of screen it then comes on like it should.

Try pressing the ‘i’ button on the remote’s number keypad . There is a ‘self check’ feature that activates if the blank screen and no sound is a settings problem. After that, press the tv/av button on the top of the set to get your tuner back on screen. Thereafter, to avoid having to repeat this every time you use the TV, just unplug it rather than turning it off by remote (- switching off by remote seems to trigger the problem that puts all picture and sound settings to zero one-by-one.)

Try unplugging the TV and then plugging it back in. And see if the power light blinks at you. If blinking, are they blinking after plugging it in, or after you turn it on, and how many blinks? This will help troubleshooting the problem. Other useful information would be model number.

For my problem its blinking 4 s

Red light is flashing five times. I switched it all off overnight so for more than 15 hours because the picture kept disappearing and I had to switch the screen on and off to get the green light and a picture. That eventually stopped and I got sound only. So after 15 hours I’ve tried switching it on and the light is flashing. And held the power button on for 1 minute. I’m demented and not sure what to do? Can you help please?

Mine is blinking 8 times

Mine blinked 7 times

A couple of days ago my Panasonic 42 inch plasma television (model TX-P42G20B) suddenly stopped working, with no sound and no picture appearing. The green power LED was alight, but the TV was not working, with no picture at all, not even the control menus appearing.

The repair engineer who came around fixed my TV within minutes, by holding down some button on the TV for some seconds to get into the engineer's Service Menu, and then reseting or changing something (I did not see exactly what he did).

He told me that TV engineers suspect software updates sent from the BBC to the BBC iPlayer in the TV cause of this problem. There is no proof of this, but this is apparently what some repair engineers suspect.

If this is the case, then this problem has probably happened to many people throughout the UK, and I would think that lot of people will just have gone out and bought a new TV, because it is often cheaper to do this than paying for a repair, if the repair turns out to be complex (but this repair was done in moments just via the engineer's menus, without needing to take the back off the TV).

Thus this presumed rogue BBC iPlayer software update containing a bug (assuming it was the cause of my TV going kaput) may have caused a lot of people to throw away perfectly good TVs, and to go out a buy a new TV, which is not necessary at all.

This is a fix the engineers use: Turn on the TV at the set. While the light is flashing, press and hold (-/v) button on the TV itself, and press 0 (zero not the letter o) on the remote control 3 times quickly within 2 seconds. This should start the screen and sound, so before it goes off again go to System and Update your channels. This worked for me!

Hi @Anthony lee Hirst ,

If the panel is cracked it cannot be repaired.

It needs to be replaced if you can find an exact replacement panel that is, as they are difficult to find. If you do happen to find one it most probably will cost nearly as much as a new TV.

Disconnect the power from the TV and then remove the back cover.

Look for the panel part number which is printed on the back of the panel and then search online using the part number to hopefully find suppliers. You may be lucky.

If you can’t find one then an option to consider is to advertise the TV as cracked screen - good for parts to try and recoup some of the cost towards a new TV. TV circuit boards are always in demand.

@James Cooper

Here’s a link to the service manual for the TV.

On p.23 it shows that the error code that you have, indicates that it could be either the LCD panel or the P board.

You could try performing the Self Check procedure as outlined on p.22 but if that is no good then you may have to start testing the P board voltages etc

The schematics for the P board begin on p.77

I had the same problem. This was the led light strip problem. Then I replaced the part from https://tvpartscanada.com/en this website.

I have just had this problem too today. I tried many many things with no success at all. Nothing changed whatsoever. Then, for no logical reason, my wife changed the remote-control batteries which totally solved the problem. Lord knows why. I had previously been using the on-tv buttons (TV, AV etc.) as well as the remote so cannot arrive at a logical explanation.
