Turn on the xbox360 and the tv does not get the signal. I took all the cords off, put them back on and got the signal with a red tint to screen/video.All commands from remote work fine.

If you're watching UK TV broadcasts then we don't have a need for tint. Similarly, with HDMI sources you shouldn't need tint either because the TV's colour decoder isn't active.

Tint is a throw-back to the American analogue TV system called NTSC. Their system doesn't lock the colour phase to the sync signal. So depending how far the TV was from the transmitter the colour would be further and further out of whack. Hence the industry joke that NTSC stood for Never Twice (the) Same Colour ...N - T - S - C. The Tint control was used to re-time the colour signal. The UK didn't have this issue because our TV system (PAL - Phase Alternate Line) includes information to lock the colour signal phase.

Strictly speaking, Tint is only required with NTSC analogue composite signals. This is where the brightness information is mixed with colour on a sub-carrier frequency. So, that would be signals via an aerial lead or from the yellow video connection which is how most of us first see a composite signal. These signals are encoded as NTSC. Any signals where the colour and brightness (luma) information is kept separate shouldn't need Tint. So, S-video, Component and RGB at 60Hz all bypass a TVs NTSC decoder. If the TV is correctly designed then the Tint option should not be available. Some TV manufacturers break the convention though, for the simple reason that many old school US consumers grew up adjusting Tint, so it's too much of a culture shock to take away that feature.

To recap then, if Tint isn't available then it's because the signal doesn't need that adjustment. The colour timing is already bang on accurate.

Check that all cables are intact and plugged in correctly.
Turn of the TV completely. There might be a manual button on the tv for this. As the last thing, remove the power cord from the power outlet in the wall or where it is placed. Wait 1 min. Then put it back in, swith it on and turn on the TV again.
If this doesn't help and you have tried replacing the cable that you get the picture from (VGA, DVI, Antenna etc.) then it is most likely broken.

You would definitely want to try using a HDMI cable.
Your current hookup requires signal conversion too many times resulting is quality loss and more chances of introducting errors and this might be where your red tint is coming from.
Assuming AT&T is providing you digital signal at 720 resolution or higher, the box then has to convert back down to composite video (340 resolution) in order to send it to your TV over the basic cable cord. Your TV then takes this low resolution signal and blows it up to fit your nice new flat screen TV.
Skip all that and use HDMI and you'll get the best picture that your provider is sending you. The digital input stays digital and is passed onto your TV over the digital HDMI cable with no loss to video or audio.

Check the LVDS cable !!! It is the cable that supplies the video signal from the main board to the LCD controller. If wiggling the cable clears up the problem or invokes the problem, you need a new LVDS cable!

Good Day,

Try resetting the TV by unplugging from wall outlet for 3 to5 minutes then plug back in. If no fixya take front grill off and panel and adjust the screen controls, turn color off adjust for Black & White Picture. Good Luck, big IRISH.

check the CRT section if there are resistor open,transistor drive of red color is leak,resold the red section of the CRT.

turn off xbox, unplug the av cord from back of xbox.. power up unit without av cord.. wait til unit shuts off by itself.. reattach the av cord and turn it on..

HI,

Try reseting the TV first by unpluging all the cords for 4hrs and then plug it back.

I will be posting more troubleshooting steps..

I would check the green signal all the wat to the display screen to determine is this is a signal problem or a system short. I would recommend that you take this set to a qualified electronics technician

This is an indication that the red gun is being driven too hard. Have you tried to adjust the red color control? If not try this first and if the control can not adjust the color then you will have to find out if the control grid on the red tube is working and has the proper voltages present. Which you will need the following equipment to do. Multimeter Oscilloscope Along with these you will need a schematic to show you what the signals and voltages should be. And I might also suggest having a pattern generator and using the color bar signal since more then likely that is the one being used in the schematic as the reference signal.
