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 picture appears on screen


without seeing the set this is a hard one to fix if the button is slack when you press it then the button is going to be the problem otherwise it could be a transformer that has gone in the set, 12 years is a good age for a tv so i would suggest replacing it with a new lcd or plasma.

Good day.
I believe there may have been some parts that were burned out due to high voltage. There are cases where insects such as lizards penetrated and got stuck then got stuck then got electrecuted inside. You can open the back cover of your unit or better, refer to the repairman.

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
