Blue green tint on smart board screen - Hitachi 50V500 50 in. HD-Ready LCD Television

Here is the Board Kit for the set. The switching on and off is likely to be the power supply.

WiFi issue if likely due to interference, where the television is located and a weak signal. Connecting via Ethernet is always preferable.

You can swap boards out and see if it improves the blue tint.

The screen being green on your TV is either caused by a loose or damaged cable connection of a media component to or from the TV or it could be that the TV's T con board is having problems and it would be more cheaper to bu a new TV than to try and fix the one that you have is broken.

Hey Noel, that is just a T-com board problem. Replace the T-com board.

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

I have a good but with green tint on a polaroid tv model number 64SX505Y-DC02

im isf certified those settings are right on the money straighter than a ruler

Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

does it have blue video image?

first try going to the menu on the tv and adjusting the red blue and green tint....if not the u need to remove the front pannel and move the the the top left knob on the setting to lower the tint...

Loose connections in CTR board ( picture tube), resolder it.
