Sony KV-27HFR TV, no picture no sound; but got HV


The high voltage transformer may be the problem, because it feeds back secondary voltages to different parts of the set, for example is the vertical deflection voltage present at the ic, if memory serves me there should be around 26volts, if it's missing it means the fuse is open or the flyback pin is not generating the voltage.

My SONY KV-XF21M80 produce a hissing (sparking) sound


That model number is not correct. What is an EHT? Must mean HVT High voltage transformer. If this set is 26 inch or smaller replace it. If larger yes replace the transformer.

yes, its dry solder joint problem in Vertical Deflection Area. If you know how to repair TV, then open it and resold vertical output IC pins and surrounding parts with solder iron and solder wire.

Sounds like you have a problem with the high voltage regulation or the power supply. This condition is called "blooming" Stargazer

Sony CRT Tv (KV-T29SZ8)


When you see white lines at the top of the screen, it means that the pump-up capacitor next to the vertical output IC is bad and the IC is about to quit. When the output finally quits, you get a black screen with possible dim spots. The vertical output IC and its pump-up cap will have to be replaced, and the little fuse resistors next to the flyback in the + and - supplies to the vertical output IC must be checked too. If you have experience working on TV's then you can do it yourself, but if not then have the set serviced by a tech experienced in Sony sets.

Check first for bad solder on the vertical IC, Im not sure for your set as I do not have the service manual, but it may be location IC301. If after resoldering it does not fix it you may have to replace it and you should replace the electrolytic capacitors in the vertical section. Hope this helps. Don

NO PICTURE


do you see anything on screen.no picture doesnt mean no raster ,raster mean anything that comes out in display.no raster with sound only mean failure in either,connection in heater which means, loose connection or some new sets declare failure in vertical circuit.so be more specific ok?

Sony trinitron 32 in. pip no video, (raster, with audio)


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.
