Best way to determine whether the RGB (greyscale) is the problem or if it is a R-Y chroma difference fault, is to turn the colour all the way to minimum - if you get a true B&W picture, the tube is OK. Turn the colour back up - if you see a greenish-blue picture = little or no red, meaning a R-Y defect.

If the greenish tint appears in the colour content of the picture (most noticeable with people's faces), but the greyscale is correct, it is most likely a R-Y problem caused by the jungle IC and/or several electrolytic capacitors plus other components in close proximity to it. This IC may or may not be socketed, either way if it is found to have a partial failure, it will need to be replaced by a competent technician in a fully equipped workshop. The only hurdle there is the potential costs involved (if you submit the TV to a service centre and decide to go ahead with their repair quote).

The quote will allow the workshop to ascertain whether it is an RGB or R-Y chroma issue in the jungle IC. Up to you what you do from here.

The greenish hue cannot be adjusted from the menu. One has to do it from inside.First confirm by turning the color settings to zero using the remote. You should get a clean black and white image with no traces of any color ( inc: green ). If your TV is greenish , the green drive on the base of the picture tube has to be trimmed.
All you need is a screwdriver. There are dangerous voltages inside a TV, some as high as 27,000 volts !!!. Where the color adjustment has to be done there are voltages as high as 110 volts and 8000 volts.If you still want to make the adjustments yourself revert back for instructions

Green hue


Unplug the TV from the wall and plug it back after 45-60s should fix the problem. However, it will come back from time to time so the same procedure will reset the video board. You'd want to upgrade the firmware on the ATSC tuner as well because old firmware was built before the final standard and when the TV goes digital in June 2009, it wreak havoc on all older HD TV. Go to hitachi website and download new FW for your TV. Copy the FW to an SD card and follow procedure from Hitachi to upgrade. It works wonder for my TV after the upgrade.

Toshiba Rear Projection TV picture color is now a greenish hue


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

It went this greenish yellow hue


Try resetting the monitor to defaults if possible. If you still have the greenish yellow hue then at that point, try another known working monitor on the computer, if the hue goes away then you know the original monitor is bad, if you still have the greenish yellow hue then you know the video card is bad.

Sony KP-53HS30 Projection TV has pink and blue hue w/timer blink


Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:
  • Cool: Gives the picture a cooler, slightly bluish appearance.
  • Neutral: Gives the picture a neutral, more natural look and appearance.
  • Warm: Gives the picture a warmer, slightly reddish appearance.
If your TV has a Hue setting, follow the appropriate step below to make adjustments:
  1. Move the setting to the right to reduce the reddish appearance.
  2. Move the setting to the left to reduce the greenish appearance.

1}DVDR 3480 playback on many Dvds widescreen insteadof 4.3 as set. 2) my Vcr. has 3pin phono. Dvdr scart to Phono .Xt2 says nosignal. Phono tophono (cam socket) no signal .cannot copt tape to DVD. 3)B W...


1) The 4:3 / 16:9 option only optimises playback for that particular type of TV. The 4:3 setting also allows you to set the output between:

  • 4:3 PS - expands the picture vertically and horizontally which gets rid of the black bars, but you also lose the left and right edges of the picture.
  • 4:3 LB - Letterbox format, displays the full picture from the disc, with black bars top and bottom.
The PS option loses the bars on 16:9 widescreen DVDs, but may still leave bars on true cinema widescreen DVDs, which are 21.7:9
This is normal.
  • 16:9 - Optimises the picture for a widescreen TV. Again True cinema widescreen DVDs will still have black bars.
2) All of the external inputs will show "No signal" until there is actually a signal playing into them.
EG to copy VHS to DVD, you will need to select the relevant scart or phono input, and press play before the recorder will register a signal and allow recording.
Some bought VHS videos have copy protection, and may cause problems when copying to DVD.

3) Greenish playback maybe caused by colour setting on TV being too high. Also check Hue or Tint settings on the TV, if it has them.

4) For some reason, in their infinite wisdom, Philips omitted the Video Plus facility from this model.

Red tint is gone


It sounds like the red cable on your component input is bad, one way to check this is press menu and see if the menu bars and letters are the right color. if they are then you may have a cable issue, if they are bad you may have a bad DG board in the unit. This will probably require a service technician. Hope this helps
