Cloudy patches from backlight leakage in LCD TV

Is it true that almost all LCD televisions suffer from backlight bleeding? This is what I have been told by the local Philips distributor here in Malta. This backlight leakage is very annoying especially during dark film scenes, it appears as cloudy patches across the screen. I dont know why no reviews ever mention this issue. I have a feeling that consumers get the worst quality products while those sent for reviews are carefully selected. I had my TV replaced with another one that suffers from the problem only worse than the first. I am now afraid to change it again. The cloudy patches' pattern seem to change and sometimes, but not always, it becomes hardly noticeable after some time (usually an hour) from switching on.

I have found that lowering the brightness level does not seem to affect the backlight leakage problem. However, I have found that increasing the brightness makes the bleeding less obvious as blacks become more gray and mixes with the cloudy patches. In this way the contrast between the two is less and hence the problem is less visible. However, this reduces picture quality significantly as blacks are less black and the colours are sometimes washed out and I will need to change settings again.

Blurred picture, double picture on the tv screen

MB, your set has one or more defective LCD panel tabs. The only true fix is to replace the screen which will be big $$$. There are youtube videos that will show you how to patch the problem. Just search LCD panel tabs and several videos should come up.

Sony klv 32s530a lcd tv program sound ok no pitcure but backlight ok

unplug everything and test one input device at a time (ie, game console, computer, tv, cable, etc) and select the appropriate input for whatever you plug in.

could be the device being plugged in and not the tv at all.

Also, do you get a menu when you press the menu button on the side of the television? If so, true, backlight could be okay.

If all this fails, turn off and unplug tv, remove rear panel, and, one at a time, unplug and plug in every connector jack (cables) that you can find on the back of the unit. check for loose jacks/connectors, smell see if anything smells burnt.

Lastly, try not to electrocute yourself when inside the tv.

My samsung tv replace the power supply board. got sound no pictuer replace the backlight inverter stell no picture

You have to check whether the back-light inverter gets its proper voltages to function. There as many voltages that controls the back-light inverter. Check these is a skilled work. Contact any experienced service technician. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Recently I purchased Toshiba REGZA 47 XL 700 E is LED. Is this TV LED ?

Yes and NO your tv is a LED. To be exact it is a LED Backlight LCD TV. An LED-backlight LCD television is an LCD TV that uses LED backlighting instead of the CCFLs used in traditional LCD televisions. It is not a true LED display but is called "LED TV" by some manufacturers.[1] The use of LED backlighting has a dramatic impact, resulting in a thinner panel, less power consumption and heat dissipation, and a brighter display with better contrast levels. You can go to and look at the complete specs for your tv

No picture problem on Philips Flat TV 37PF5321 37 in HDTV-Ready Telvision

I am suffering from the same problem. When I turn on I get sound but no picture, although I do get the backlight coming on when I turn it on, I then get about 1/2 a second of picture then nothing. Even if I select TV specific functions such as the menu, I get no menu screen come up.
Any ideas out there?

Picture shuts off

Is there a dark patch when you see the picture, easiest way to check is on the tv tuner with no cable attached, this way you have a grey static screen, if there is a darkness across the screen when it lights for that breif moment, then it may have a broken backlight tube. Had the same problem with my 32" LG.

I've noticed a dark patch in the lower right corner of the screen. Is this a bad panel or backlight? It's mostly visible in scenes containing blues.

Sounds like a backlight is out probably due to a bad inverter board. If you can see the spot when the tv is off its probably a bad lcd panel.

Black parts of screen looks light light is shining on it

Your LCD TV uses backlights and they can be slightly visible when viewing a letterbox movie.  However, if the light is really bleeding into the black, there could be a problem, but mosty this is common.
