Question about Sony FD Trinitron WEGA KV-32FS100 32" TV
I was given a sony trinitron 32in pip tv, when it's powered up, audio is working, but the video only displays a monochromatic screen with regularly spaced lines (I think, this is called raster?) Is this a shorted picture tube? Or, are these sets prone to cold solder joints?
What you have described there is a classic example of the jungle IC failure. Ic301 Sony p/n 8-752-101-04. A pic with no color, and lines or grainy texture in the picture. Not a project you want to tackle if you don't have the proper soldering equipment or skills. And not a costly one at a good repair shop.. Only real hurdle is getting that heavy monster into the shop. To answer your question, yes what you described there is raster. Even the salt & pepper looking screen with no real decernable image is described as raster. In fact any image generated on the CRT is raster. And yes, these sets are prone to solder joint problems, usually ring cracking in circuits that generate the most heat.

It's sort of the solution, I thought it would be. Nice to know I was on the right track. Thanks for the good advice, and fine diagnostics!
Raster blooming. Can fix vertical with service menu, but horizontal does not have enough range to correct
