Lcd tv no pic no sound just blue screen Was watching movie picture and sound disappeared nothing but blue screen is there a fix for this?
Most of the new TV's display a blue screen when there's no signal for it to lock on. Try unplugging it for about 5-10 minutes and see if that clears up the problem. Why? …Because they have microprocessors in 'em (computer chips) and just as like with any other operating system, they can hang up or crash. This isn't an uncommon problem with today's TV sets. Unplugging it for awhile resets the microprocessor (in other words, it causes it to re-boot when you plugit in again).
Westing house tv has a light black square in the center of the screen
Most all do. I can't think of a brand off hand that doesn't. The power supplies and microprocessors can generate quite a bit of heat and need do be cooled. Convection… cooling just isn't enough.

Well too much of anything can be harmful. If you turned the brightness of the LCD as high as it went and stared at a white flashing screen for some time I'm pretty sur…e that couldn't be "good" for you. But for general use I know of no one having eye problems from using an LCD monitor. Actually LCDs are safer on the eyes than traditional CRTs as the refresh rate (Hz) rating doesn't have to be high and the screen updates in a way that causes less strain on your eyes. I use an LCD for hours on end day after day. On my last eye exam I was told that my vision and health of my eyes had improved since I switched from using a CRT.
If it's a TV that uses a projection lamp, then the lamp or ballast is going bad.
TV turns on picture is erratic andhas lines going through it and there is no sound you have to turn the tv off and on again to make it right Today the whole screen turned green?
Hard to say. If the TV is a Westinghouse I know they had a bunch of TVs that had this problem. It wasn't fixable. You had to unplug the TV from the wall, wait 30 se…conds, and plug it back in to reset it. It would be good for awhile and then happen again. They recalled those TVs. Otherwise you will need to get a tech into your home to take a look at it.
Your 60 sony lcd projection tv goes on for a few seconds and then screen goes black and sound goes off-goes through same cycle until you turn tv off any clues?
I had an 30 cycle till it would come back on I had to change the bulb works fine.
It's not much different from how your calculator or digital wristwatch works, except there's a light on the back and instead of just one color, you have a fine mesh three diff…erent colors. See the related links.
Samsung LCD TV, no picture but sound is there. I have more than 100 Samsung LCD TVs, series LA32 and LA40, under my care. So far in the past three years i have this pr…oblem only because of LCD Back light inverter. please check LCD's back light inverter circuit for proper function. it will not cost much for the repair of the circuit if you do it by yourself.
Press up or down when you are in edit mode, and it will change channels. Try pressing up and down on other things as well.
There are several things that can cause a lcd tv to have sound but no picture. If the backlight of the lcd panel comes on momentarily when first turned on, the problem is most… likely caused by defective backlights which are part of the lcd panel. If there is no backlight when first turned on problem may be inverter circuit or power supply. If the backlights come on and stay on the problem could be the tcon pcb or the main pcb. The tcon is sometimes available but most of the time part of the lcd panel. Unfortunately this symptom usually is cured by replacing the lcd panel which is most cases is cost prohibitive.

Why would an LCD TV make noise like gas was leaking and the screen is blank but there is still sound?
Perhaps a screen failure? I would turn it off and ring the hotline or look at the Owners Manual. (PS, I might be wrong because this is my first ever answered question)
Last month I bought Samsung 3D TV. After few days due to the power problems the TV screen is going blank for some time quite commonly. I am frustrated and wanna change that. Plz Suggest me best 3D TV.?
If power problems are causing failures with a Samsung television, expect them to cause problems with any other make of television. If the television is faulty after only one …month, the television will have a manufacturer's warranty that will enable you to change it. Before you install the next one, make sure you have a stable power supply to avoid future failures.
LCD screens do get warm during normal operation mostly because of the heat given off by the backlights. LED backlit televisions run cooler than CFL models but they still d…o show a temperature rise. If the television is becoming hot rather than just warm, there may be a problem with either the television or the ventilation around it. Make sure that there is free airflow around the whole television as that is often the cause of overheating. If the problem persists. contact the manufacturer or your vendor. A LCD display should never become uncomfortably hot to the touch, and excess heat may indicate a problem within the set.
