The picture tube is gone.
i repaired 150 sony xbr and kv series with that problem.sony 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.

Ed might be wrong....

I have a kh-32fs13 Trinitron with the exact same issue, only looks good when dark, and even then it only looks good in the center.

I opened up the back cover and turned the focus knob on the flyback transformer clockwise a little bit and it fixed it! Full brightness with a chrystal clear picture!

Blurry & Fuzzy Picture Sony Trinitron


Check the filter capacitor to the supply to video output card. You can locate this capacitor at the CRT base card to your Sony Trinitron. Replace this electrolytic capacitor.

Sony KV-27HFR TV, no picture no sound; but got HV


The high voltage transformer may be the problem, because it feeds back secondary voltages to different parts of the set, for example is the vertical deflection voltage present at the ic, if memory serves me there should be around 26volts, if it's missing it means the fuse is open or the flyback pin is not generating the voltage.

Sony Trinitron model # KV-27HFR- the picture is fading, is there a way i can fix that?


From your descrition the problem is the picture tube, over a period of time the guns build up crud reducing the emission on the front screen which in turn causes fading and progressively gets worse until viewing becomes impossible. One possible solution is to have the picture tube rejuvinated by a tv tech to buy more time out of the set, but the improvement may last a few days to several months or more.

I have a sony trinitron 36in tv, the screen works fine, colours are all great, no flickering or random shapes at all, its just a little blurry around edges, especially small text, its very blurry and...


it is very easy you just need a very small straight edge screwdriver

you should try to adjust sharpness setting with on screen adjustment first

if tv is too old tube might be going "soft" and sharp focus might not be able to be fully achieved anymore

good luck

Hi...I'm thinking about buying a 2 year old Sony KV32Fs-120, is this a good tv and are there maintenance costs involved in having a tv like this? Thanks, Nancy.


The Sony TV'S are one of the best sets you can by on the market, the Trinitron picture is world famous when it comes to picture and quality. Since it is two years old makes it a good buy, maintenance costs are low compared to most televisions.

Our Trinitron KV-36XBR400 powers up then no picture


How old is this tv?More than 5 years old.Not worth it to repair CRT tv at this prices.Tries unplug,replug an hour later,might help,see if reset itself.U can buy a pretty good 32" LCD tv at $400 or less these day.It not heavy as the CRT tv,it alot easier to move the tv around the house or other locations.

Blinking picture


TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.

The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.

He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...
