Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Why is my LG 32LC7D TV taking 5 minutes to have a picture when turning on.?

Likely signs of a issue that is going to only get worse---could be in power supply of set (first place to look) or could be main board or something that it controls.

Kind of like "My car runs rough when cold" it is a issue that is not full blown yet.

It is pretty much junk, sorry to say it but your picture tube went out and it is cheaper to buy a new t.v. My grandpa use to fix them for us for free but he passed:( If you call some where see how much they would charge for a picture tube, I bet it's expensive???

I've got a Polaroid TV and have had nothing but issues with it. Try unplugging it and leaving it for 10 seconds then plug it back in.

You might also have pressed the PIP/POP (Picture in Picture / Picture on Picture)button, which basically tells the TV to display one input on top of another. I could have the name of the button wrong but it's something similar. If you get it to power up again, try hitting that button till it looks "normal" again.

The power went off today for unknown reasons at my house while I was watching my LG TV through my LG LHB335HTS which is hooked up with HDMI Cables. When the power came now it will not show a picture...

I was able to fix this issue by changing the screen resolution to auto on the home theater system. Since I had no picture on my tv, I had to unplug it and plug it into another tv. Once connected to the other tv, I was able to access the menu and change the resoultion to auto (it had been reset to 480dpi, this is why it didn't work on my main tv). After I set it to auto, I was able to get it all to work. My niece had been playing with the button in front of the device and apparently the sequence of opening the DVD tray and pressing the stop button causes the screen resoultion to reset to 480dpi.

MY problem with Sony KP-53S35 53 in. Rear Projection Television. When the TV powers on, the red light blinks until the picture comes on, then the red light blinks go off. I had to wait more than 5 minutes...

the number of flashes of the red indicator lamp points to the possible cause of the delay of the raster or picture, but usually it's an indicator of an emission unbalance between crt(picture tube) guns. the picture will take longer to show up as the emission on either of the picture tubes goes down.

Flashing picture when start up

What i would do id purchase a can of freeze from radio shack
wait till the picture is good then freeze one ic at a time till the problem shows up, once it shows up let it warm back up and refreeze to make sure you got the correct part.
found this on anther site:
My first guess is an electrolytic cap in the main power supply and/or a voltage regulator that feeds the deflection amplifiers.

The cost of repair is not much; the greatest challenge is finding the bad cap because there are so many of them and scattered through out the sections.

If you have a scope and can look at some waveforms and voltages around the deflection and power supply feeds you may be able to zero in on it right away
