TV SCREEN GOES BLANK

My TV will play fine for 10-20 min. after that the screen will go blank. Sometimes the screen will light up but no picture. I have no problems with the sound. When I unplug the power cord for a few min. and plug it back in the TV works for a few min. and does the same thing over again. The TV is only about five months old. None of the vents are blocked and nothing has gotten inside of it, and I have always kept it pluged into a surge protector. I have been the only owner of this TV. Please help if you can, and thanks for any advice...

    same problem, it goes blank when it gets hot

  • Anonymous Jan 30, 2008

    I have a new Sony Bravia XBR5 and had the black screen issue from the first day. But the solution seems to be to forget the fancy HDMI cables and go back to some good high quality component cables. I truthfully cannot tell the difference in picture quality and it is minus the black screen problems. It hasn't done it since I went back to component cables from the cable box to the TV. I have the DVD set up with HDMI and have watched several movies with no problems. Hope that helps someone.

    perfect sound, no picture at all even after being unplugged for a while.. any idea's?

  • brenden griffen Jun 16, 2008

    My TV screen goes blank after 10-12 mins also. The sound still works perfectly while the screen is black, there is no picture though. I turn off the power and it starts up fine, but 10 mins later it does the same thing. Its like my tv goes into "hibernation" mode with the sound still running. Any suggestions? The sleep timer is off and it does this whether I'm watching a DVD or playing a videogame.

    I have a samsung 40" LCD Tv and it has the same problem. The screen goes blank after 5-10 minutes but the sound is still on. I cut it off and then back on and the picture comes back but after 5- 10 minutes it disappears again.

    I have a Samsung 40" LCD...I've had it for two years now..and have never

    had any problems..Until now, I bought it in Jan 2007..Now its late Jan,2009

    Last evening I was listening to the tv while I was on my lap. I looked up and, my screen was black..I knew it was still on cause I could hear the sound. So, I turned it off, then right back on..It came back on..and then in

    about 10 minutes it was off again. It did this at least 5 times...Then it stayed after that..Well, I thought it was over...but, tonite its doing it again.

    What is wrong with Samsung...its suppose to the best...I had always bought Sony...cause I had never had a problem with Sony..But, Samsung had a better picture...Now, as I write this; it has gone off again. I should have bought a Sony...!!!

    I have the same problem with my Sony LCD - it is not due to a sleep timer, because if that were true the whole thing would turn off and there would be no sound. The sounds continues fine, it is just the screen that goes blank.

It's not because of a sleep timer or any other settings. I have a similar problem with my SONY Bravia and it started after only 7 months. Sony has sent technicians to my place, had the TV at their place etc but they say the problem doesn't appear at their service center so they can't fix it. (They've just updated the software (3 times) but that has not helped at all.) I say it's ******** and I will report them to the consumer organisation. They also said they had never heard of this problem before, and that is very interesting since I found about 100 webpages where the problem is reported...:-( Never buying a Sony again!!!!

Re-program your CTV and set the timer OFF, after a while if the problem goes the same. you may refer to qualified technician.. for further check-up of the unit. it will posibble in the primary regulator section/hot section.. or leak spare parts at the supply section.

SOURCE: TV SCREEN GOES BLANK

Yes your inverter is bad, I have the same problem my set is about 1 and 1/4 years old. Because Olevia makes a terrible product there inverters are attached directly on to the panel, which means they will only sell the inverter along with the panel i.e $700+ to replace + $100 dollars labor if u don't know how to fix it ur self. I am currently searching to find the manufacture that makes the inverters because olevia will not disclose that information. I believe it is darfon, if so the inverter should cost about $150-200 depending. If you dont believe you can fix it ur self ur best bet is try and sell the set for scrap take ur $100 or so dollar and buy a quality product! Oh and dont call there support they will tell 10 different things before u find out this long for seen truth!

Most of you that are having problems,it has nothing to do with your screens themselves,but with the capacitors in the power supply,the caps,over heat and the tops pop out and the dry out and are no longer any good,a soldering iron,solder,and flux are really all that is needed to repair this problem,get good caps at radio shack,or equal location,pay attention to polarity on the two contacts on the bottom of the caps,replace all that are poped up

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know
