It will depend upon individual viewing taste. Yet, contrast 65%; Brightness 50 to 60% and color 30 to 45% will give a satisfactory picture. https://electronicshelponline.blogspot.com/
May be you have switched the settings from PAL to NTSC or vice versa.Pal with give colour on European TV NTSC with give colour on American sets but sometimes black and white vice versa.
HI, Check on thing Go to the SETUP Menu and check is there is any System settings (colour system) on both DVD and TV . Try all the settings available in the colour system setting. As you didn't mentioned anything about Brand and model number of the player or tv. Its not possible to give you the exact solution. Ajin
Generally Tv screens use three different colours to make the picture, and if one or two of these colours don't show you will see the picture but in specially one colour (like looking through a red filter in your case). If you are using an input into the TV (DVR or Games console etc) then I would firstly move the cable around in the back of the TV and the console to see if anything changes or flickers in and out of being correct. If this does happen I would recommend buying a new cable to fulfil the purpose. If this does not happen and you are still seeing red then there may be an issue with the connection inside the back of your TV, this shouldn't be a very expensive issue to fix as you are still getting a picture but I would recommend getting a specialist to check it out if you are not confident in fixing this manually. Thirdly and most unlikely is the settings inside the TV have changed, some TV's like yours will allow you to change colour settings on the screen. I would go into the menu and find the section that allows you to change the colours and have a check to see if any of the settings seem off.
can you use the vga source from your laptop to the pc input on the LG a standard vga monitor cable will do then set your laptop to output the vga signal
it is due to poor focusing
please check
1 set with focus control fitted on flyback transformer,
2 check focus control wire comes to crt base is loose or some foreign material deposited on it.
3 crt base loose contact.
4 if tv is old then there is a possibility of crt is getting weak.
if you are not a technical person do not open set as tv has very high voltage inside.
hope this will help.
With the set being 12 years old, I'm sure the picture tube is near the end of its useful life. You probably have a defective semiconductor, either an IC or transistor that has gone up giving you no color, but with the green picture, it is not likely worth repair.
