Question about Sony KV-35S45 35" TV

1 Answer

No color My Sony Trinitron KV-35S45 was manufactured in 7/98. Suddenly, without warning the color was gone. The picture is sharp in black and white. Initially, I could turn it off and back on and the color would return but that only worked for a day or so. Any suggestions? Thank you, Mike

Re: No color

If the settings are correct and the signal is good but there is no color, it can only be one of 2 things - the CXA jungle IC and the chroma crystal next to it. If you have never replaced small parts on PC boards then have a qualified tech handle it for you.

My HP dv6000 laptop screen goes black suddenly, without warning. It is solid black if on battery power; if I have it plugged in to power supply, it is black with flickering white lines.

Your inverter is failing. Under battery power there is not enough DC power for the inverter to convert to High voltage AC power and it goes black. Even under charging, there seems to be evidence that the inverter is failing because there it is unable to consistantly convert the needed power. Check the cables on the back of the display and change your inverter.

Sony Trinitron kv-27HFR blurry

the picture tube is gone.
i repaired 150 sony xbr and kv series with that has a single gun not three and has a great pix,but burn out faster.
there is a main screen control that you can adjust ,but the tube is gone.
on the back of the crt there is 3 gun drives r g b .
turn the color all the way down so it is black and white.
if there is a green ore purple tint,one gun is out of balance.
ajdusting the r g b controls so that black and white is normal is what you want to do.
the crt board has the screen bias voltage 800volts on it so be very careful and use an insulated screwdriver to adjust the drive controls.

Have you tried disabling SVM (scan velocity modulation)? Often touted as a "feature" of TVs, it's a way of artificially making a picture appear sharp. Totally unnecessary. When SVM (sometimes called VM) is on, it can lead to some color bleeding around edges.

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.

Picture Problem

Your TV's tuner is the problem. 1st thing to try is just to sesolder its connections to the main circuit board. If that doesn't work replace the tuner. Also could put a meter on the power coming into the tuner and see if it is drooping in sync with your picture. Tuners are not that expensive to replace.
