Yellowish/pink tint on parts of the video

I have noticed yellowish/pink tints on only parts of the video and even if I have reconnected the hookups the spots still remain in the same place on the screen. Please let me know what this could be for I fear being ripped off by a technician.

Re: yellowish/pink tint on parts of the video

This is a contaminated light engine, this TV is notorious for this. A techniciian who is familiar with this tv can TRY to clean it with canned air and a tiny brush. Panasonic even has a part number for it (basically a water color paint brush). The disassembly and procedure is involved and the results are mixed. If it can not be cleaned the only option is to replace the engine which is not cost effective. It will probably cost you a couple hundred to have the cleaning procedure done but some technicians will be hesitant because it is a lot of work and if it does not solve the problem most people will not want to pay the labor for little or no results. Good Luck

Entire screen has a pink tint. Can change to blue with settings. Cannot change to natural with tint etc.

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.

Here is something that may help from the website under your model number television. Q. Why are people on my screen green?
Models: 32HL17, 37HL17, 42HL17, 42HL167, 47HL167, 52HL167, 42HL167, 42LX177, 46LX177, 52LX177, 57LX177
If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
