SOURCE: lg lcd tv screen goes

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

SOURCE: LG RU-42PX11 42 plasma TV has black bar

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.

I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!

SOURCE: LG 50PG20 Plasma,, nothing shows on screen its all black

This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.

When one or more of these boards fail, the screen stays black, and you only have audio & on/off.

You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.

Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.

What zip code are you in?

SOURCE: Hi, my 42" LG TV

Hi, the appearance of black streaks on the screen of a Sharp LCD TV is common problem most customers will have to contend with. One of the most visible signs is the appearance of a message that reads " loss of sync". In this situation, the individual will still hear the sound coming from the LCD TV but the picture disappears especially within 10 minutes of putting on the TV. In some other cases, small horizontal lines may develop on the LCD screen especially when an object is thrown at the screen -the horizontal lines develop at the spot where the object hits the screen, and these lines are often visible when the TV is turned on and such problem is characterized by Grey color screen with no pictures.

Another common situation is the appearance of vertical red line across the LCD TV screen. In this case, the connection from the internal ribbon connector and the display has been effected. This problem may degenerate into the formation of two screens which are separated by a black line .

LG TV screen repair for Black streaks on screen

The best possible LG TV screen repair for vertical lines on your LCD screen is the replacement of the screen itself. It would be ideal for you to know the warranty status of your LCD TV before returning it to the manufacturer. In the case of the formation of black streaks on the LCD screen, a possible reason is that one of the substrates in the screen has been fractured or it can be a result of the release of some bubbles within the screen, especially after the screen was hit by an object. You don't have to think much about this problem, as it should be in your best interest to get a LCD TV repair service to replace the screen for you.
In some other cases, some other components of your LCD TV screen might have been broken down { hardware problems} resulting in black streaks or the formation of Grey or black color on your screen, you will need to get your LCD TV screen undergo some diagnostic procedures before the problem is fixed. This will help you avoid future re-occurrence of the problem.

Thanks for using fixya.....

Blu ray shows the "Blu ray Disc" Logo on TV screen and then just show a black creen

Hi! and welcome to Fixya!

It looks like your tv is unable to handle the output video resolution from your bluray. The reason why you do not have picture on the tv screen after the bluray disc logo appears.

You can follow the instruction below to set the video resolution on your player to its lowest resolution:

1. Using your bluray remote control, press the following buttons in order... STOP button (press and release) ....HOME button (press and release)....POP UP/MENU button ( press and release )
Note: press the buttons in order with 1 second interval. Make sure tv and bluray are ON when you try this. If first attempt nothing happens, try this again.

2. When the home menu screen appears after doing the above instruction, you can set the video resolution again manually. Follow the instruction:
Using the BD remote control press HOME button > then go to SETUP > select screen settings > then change OUTPUT VIDEO RESOLUTION to Auto > change also 24P OUT to 1080P // set the BD-ROM 24P OUTPUT to Auto

The next time you turn on the bluray player you will have picture again.

Let me know if this works!
