Tv Screen Problems

I have recently switched my T.V. on and the sound is heard but no picture is on the screen, instead i have a green screen with lines through it and two faded colours of blue on  the left side of the screen and red on the other.

 

The tv has also started to power off intermitently

 

the TV is about 5yrs old

 

Any ideas

    When using digital tuner with antenna there is green screen when "no signal" and when signal present picture is excessively green.
    Picture is OK when using input from analog tuner or external DVD/VCR, etc.
    Audio is OK.
    RCA help says it's the antenna input.
    I adjusted antenna, checked connections, rebooted TV.
    This problem only occurs when video is from digital tuner.
    I have not checked antenna matching transformer but that would also affect analog tuner wouldn't it?

    My son's tv does the same thing. When I turn it on it is green with lines across the screen. Sound seems fine. After a few seconds, the tv turns itself off. I cannot access menu or change the channel or AV.

Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Green Screen instead of Blue


Check the picture settings on the tv, if that is not the problem, then check all of your connections (RGB cables+RW Audio) that is HD component, if you have both HDMI and HD component then try one of them, or it may be a switch in the back of the DVD player or TV

Green picture


a green screen on power up with retrace lines. At shut down a point appears in the middle of the screen. Sounds like either a shorted G2 grid, or bad flyback. If a phospher flake has shorted the grid in the tube, you can sometimes have luck by using a megger set at 1000VDC, to burn away the short. This is usually caused by the line HV going too high causing the anti-UV protection to kick in so fit a dummy load 40W lamp instead to the line output to allow measurements to be made.

42 inch LG Plasma TV - Lost picture


Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman
