Yes it is high resistance could be your balast... do you hear the arc in the spark gap on the ballast?
if not you may have no power to the ballast as in an open fuse or the ballast is defective or your bulb is defective ..they may not look blown.

My tv is showing the green light but the screen is still black. what should i do?


If your tv is RCA P52926 then it is rear projection tv that does not have a Lamp inside, this rear projection tv three picture tubes to make picture/ image on front screen.
I disagree with previous expert given info about Lamp in this tv.
Since tv is an old model so it might got problem in deflection circuit or power supply stop working properly that is why tv is not turning On to show you picture.
Local tv repair shop will help you to get it fix.

It may be. I have replaced the lamp in my sony 3 times. Look for dlp lamps online and enter in your tv model. There are instructions online on how to change it yourself. They also show you in your manual. The power light should blink red indicating bulb failure. Read your manual. Hope that helps

When I power the TV on there is no picture, the lamp light is flashing, and there is a squeaking noise coming from there rear of the TV. It kind of sounds like a wheel turning and rubbing against...


The squeeking sound could be the high voltage trying to strike the lamp, it will try several times to strike the lamp then shutd down. Take the bulb out and see if it s blown. Even if it is not blowen it sounds like you have a bad bulb.

You set a Multimeter to read impedance (ohms) then put the two sensors of the Multimeter on the lamp contacts, if it reads infinite impedance, then lamp has blown.
