Here's my suggestion , unhook all the external components to the TV and leave the TV unplugged for more than a few minutes (a day/overnight). The next day plug the TV into the wall outlet (not the powerstrip) without anything hooked up to it, and turn it on. See if it comes on. Sometimes unplugging for a few minutes/hours is not long enough for it to reset itself.

My Sony Trinatron has suddenly displayed a dark screen on all channels. You can see the picture but looks like it's nightime. I've tried ajusting the brightness but no result.


Hello,

does the TV bring out sound even as the screen display is dark?

Problem should be from the TV lamp/bulb. When a TV bulb/lamp is dying, it makes the pictire on the screen become dark and very hard to see.

Have the lamp replaced and hopefully, your screen should be perfect as before.

Let me know if you need directions in replacing the lamp, even though it is very simple replace.

Yours sincerely.

Your problem is simple! The government has recently (in about the past month) required all tv stations to broadcast in digital. You can get 2 $20 credits to get a converter for your arial. You can just throw it out and get a new one, which will recieve in digital. Or you can buy a converter for your TV, using those credits. I'm not sure how how to get the credits.

Sony 27" picture quality


You probably have a leaky or open electrolytic capacitor in the vertical circuit. This will require troubleshooting by a repair specialist, unless you can obtain a diagram and do a little spy work with an oscilloscope
