In most cases when I have seen this type of fault, the CRT was getting very weak. When the emission is below a specific amount, the AKG circuits keep it biased off.

It is also possible to have defective components in the CRT bias circuits, high voltage area, and the scan amplifiers that can cause this symptom. This type of condition is more rare to cause a flashing screen as per your description.

--

The TV making some clicks, and the red LED flashing is an indication of the power supply going in to the protect mode. This is usually from a scan amplifier failure, or a high voltage failure, a short in one of the circuit areas, and or a defect in the power supply itself. Proper troubleshooting is required to determine the exact fault.

My Sony Wega Trinitron KV-32HS20 does not tun on and the standby light flashes 4 times. I can hear the sound but no picture and the it turns off automatically after a few seconds.


This is a tip I got from a tech bulletin.

IC600 output pins 14, 15, 16, all have aprox 130v (all should be higher) until relay clicks
then they drop off. 200v line goes up to 50v, 135 goes up to 40v.
Checked D611 (135v rectifier) it was fine. Checked D615 (It's labeled D601 on the board)
it was shorted. (D615 is the 19v rectifier for the Audio B+) Removed D615 set power up
and has good picture with no sound.

Sony Trinitron TV now taking around 5 minutes for picture to appear (sound comes on instantly) Is it worth repair or should I cut losses and replace set?


How old is the TV?
Sony Trinitron sounds like it may be from the 1980's?
Some TV engineers can use a piece of equipment to do a "tube boost" but this is sometimes risky and can completely ruin the tube, but it's a risk you would have to take.
If the TV is over 15 years old, and has been used regularly, (like 4 hours every day or more) it seems likely that the tube has reached the end of life.
TV cathode ray tubes are like light bulbs...they do not last forever!

Comes on and later goes blank


How much later? The Sony sets have a setting in the menu that turnes the TV off if there isnt' any input, Sometimes this feature gets messed up, and the feature has to be turned off, Check that out and see if that takes care of the problem.

No picture no sound


Forward voltage/current problem....needs a new board....You might try unplugging it for a few hours...If the TV starts you will need to leave it on until it gets repaired or replaced.

This may be a bad crt or picture tube. Take a good look at the picture when it's on and see if it has a pinkish or greenish tint. This is easiest to see if you turn the color adjustment all the way down. If it looks like the tint is green or pink and the focus isn't great then it's probably a bad crt. Not worth repairing if its the tube.
