Re: Sony TV - No picture

If the picture slowly fades on, the you may have a weak picture tube or a loose solder connection in the filiament circuit. If the picture flashes on then you may have a problem with the High Voltage/Horizontal circuit. This type of problem could be caused by a loose solder connection on the horizontal driver transformer. There are several other problems that could cause this type of problem. Stargazer

Sony tv model KV32S42 picture taking forever to come in

Speaking as a retired SONY dealer, the short answer is probably yes. There are some repairs an authorized SONY repair center can do but if the tube is displaying a soft picture, it may not be wise to spend a couple hundred on repairs when a new medium quality TV is three hundred to five hundred for a SONY. I applaud your devotion to a set that has served you well.

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!

No image but good quality speaker.

Sony has had a problem in older sets with-believe it or not- lack of humidity. I had one with the same problem. If it is under warentee take it back, if not-I know it sounds insane- put a large plastic garbage bag over the turned off set. Leave it that way for a couple of days. do not turn it on during this time. After a couple of days remove the bag and turn it on. If it works-that's the problem, if it doesn't- it's dying, and to expensive to fix. Surprised the heck outta' me when I tried it on my old Sony 19" set- it worked.

No picture

This can be a scan amplifier failure, failure in the high side of the main power supply, the picture tube may no longer be having emission, or the heater supply to the picture tube may not be working. There are many parts inside the set that can cause failures.

You will have to take the set in for proper shop service by an experienced TV tech.

No picture only sound

The bias supply to the CRT may be failing, or the CRT itself is failing. It is difficult to detemine without going in to the set and taking readings, and diagnosing the exact things that are going on.

Delay to see the picture

Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.

TV will not switch on

It sounds like you may be on the right track. Also you could have a problem in your Horizontal Deflection circuit. Since you say it flickered, you may have a solder joint that was arcing. Probably in the horizontal circuit. I found a capacitor which was arcing in this circuit. I was a small disk type. NOW since it is chirping, the horizontal output transistor may have shorted placing too much of a load on your power supply. The noise you hear is the power suppply trying to start. Stargazer
