Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Everything works but when you look through the lense it show's yellowish tint and that's it


Yellowish color, hey. Didn't let the dog hiest his leg did ya. Normally because of coating on the image tube plate it should be green. Let me ask a few question. Are you constently replacing batteries? What color is it when you turn off the NV devise. If you can see the white color on the plate it only 18mm in diameter. Just remove the eye pieace and lens it screws into the base.
If that small plate is off colored and there are glass tinting on back/front of the image tube. Then it has gone back to Red Star. It on it last leg, sorry, stewbison

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.

Sony FD Trinitron WEGA KV-24FS120 24" TV Color changes


Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.

Infocus LP70 - It's all Green


A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).

Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

Zenith 25" Color TV - Model A25A23W


Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck Please dont forget to rate this thread.
