My tv still works and turns on but every now and then it just turns off all by itself. We turn it back and the screen still works just turns off on its own. It can stay on for long while or for short intervals but the picture has never gone out. I’ve checked the cord in the wall and the connections on the back of the tv everything looks good. I’m not sure what it needs so it doesn’t keep doing that. Any help would be great. Thanks

Hi @jaxlb ,
Does the power indicator light on the front of the TV turn off when the TV turns off or just that the screen goes black and there is no audio either?
If so it seems to be a power problem.
Disconnect the power from the TV and then remove the back cover and inspect the boards especially the power board for any signs of heat stress to the components or bad capacitors (leaky or bulging).
If you spot something or your not quite sure, post some close up images of the power board. Here’s how to do this. iFixitでの質問に画像を追加する方法

Hi @jaxlb,
As @oldturkey03 said a TAB problem won't make the screen go black or the audio stop.
It sounds like a power problem or the mainboard perhaps.
Here's the service manual for the TV. It has the schematics for the power board so that the voltages can be checked when the screen and audio are no longer there but the power light is still indicating that the TV is on (see p.12 in the manual.
As I suggested in my answer above check the power board (it's the board where the power cord from the wall outlet connects to inside the TV) for any obvious signs of component stress and post the images back here.
Be safety aware and disconnect the TV from the power before working in the back of the TV except when testing the voltages of course;-).

Hi,
What is the model number of the TV?
Check that any air vents in the TV back cover are clear and free of dust etc, so as to allow the hot air to escape to prevent overheating. Use a vacuum cleaner to clean them if necessary

I’m not sure. How do I check the model number? Actually I just figured it out the model number is DP32670.

No, the power in dictator doesn’t turn off. I never really noticed it but it doesn’t and the screen goes black with no audio. But I did notice that when I touch or put slight pressure on the right side the screen goes black. It might have to do with a line I’ve seeing on the screen for some time now.

@jaxlb where on the screen did you see this "It might have to do with a line I’ve seeing on the screen "? This "I touch or put slight pressure on the right side the screen goes black" of course before it goes black and no audio? Bottom right side or top?
