After reading comments by Yxif, I examined the 7 pin IC (TDA8172) and discovered a bad solder connection on one of the pins. The bad connection was not visually obvious. I used a toothpick to apply a little pressure to discover the connection was loose. I reordered the pin connection and my annoying start-up problem was solved.

Thanks Yxif and all who contributed to this solution.

Picture int disappears leaving snow on screen
Resolder the Xtal in the tuner
No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
Intermittent video or snow
Resolder points A, B, C, D in tuner PCB, check cold solder on tuner shield 2-106-349-21

TV shows red

It sounds as though the color settings have been altered or that the tv is going out. Assuming this is a crt unit, you might try adjusting the color or unplugging it for a few minutes.

Good Luck,

HV Sound no Picture

Sounds as though there is an intermitant, heat-related problem with the HV transformer. You can order this at a tv parts shop or from Sony (probably more expensive) the part number should be on the part or on a schematic. If not, the parts dealer can look it up from the model number.

Good luck! :)

All the reports are showing the same problem the TV is in shutdown mode.

Something is wrong and it is refusing to start it makes a chirping or clicking sound. Solution is that it needs to be repaired nothing you can do unless you want to try replacing the motherboard yourself.

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.

Picture takes hours to appear

Spounds like the b+ feed filter capacitor off the flyback that supplys voltage to the three drive transistors on the crt board is bad.
