1999 sony trinitron color tv -no picture-no sound.

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.

The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

SONY TRINITRON TV 32 INCH MOD# KV-32FS10 SER# 9006800 PICTURE INTERMITTENTLY BLANKS OUT AND COME RIGHT BACK NEVER LOOSE SOUND.

sounds like the tube has gone any good tv repair shop will be able to replace it cheapley.

Maybe you put magnet near to your TV or something that can produce magnetism.... if not the deguassing system is not functioning anymore. .. bring your unit to near service in your place.

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.

Hii.... first I like to know the chassis of yor KV27FS100..
sound like problem with regulated parts block.....and can more helpfull if you count the blinking of the LED....sony have selft diagnostic at the LED Blinking.....

I hope hear from you soon....

Thank's

Hi. I dont recognise that model number. Take a look at the rear of set & see if there is a chassis number eg AE1. AE1A, AE1B, AE1C, AE2, AE2A, AE5, AE3B, BE2, BE2A,BE3, DE1, F1, FX, These are some of the common older chassis. You say led flashes does it flash 2, 3, 4, 5, times etc then pause then repeat ?

the 2 bilnks is a fault code for a (b+ overcurrent), you could have a bad horizontal output check q506 or q505, varies by modle. I have also run into a bad color amp ic1751. use a multimeter to test the h. o/p transistor, as for the ic, easier to replace than test.
