Re: kv36fs10 sony tv
Sony, hmmm, might be a bad adjustment on the G2 adjustment, if you have the back off, the HV transformer has the Focus/G2 control, try adjusting the G2 (Screen) control up and down to find a midpoint that the pix dosent shut on and off.

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider
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.
tap around on the circuit boards in the rear of the television. narrowed it down to the Comb Filter circuit board. It is the smallest upright circuit board behind where you plug in all your connectors. pulled it out cleaned it off, reinserted it
On Sony TV's they monitor the current drain on all three electron guns Red Green and Blue. Until all are somewhat equal it will keep the CRT blank. As the set ages it means that it might flash a few times until the cathodes are good and warmed up.
The average life of a picture tube now days is only 6 to 7 years,base on the symptom and the age of the set I hate to tell you but your picture tube is bad and it has to be replaced but a new picture tube for this set would cost more than a brand new television,I would suggest not to spend any money and invest in a new set.Sorry
If its only a few months old , get the bill of sale and go to the authorized repair shop. If no warrantee then your gonna have to take it it anyway, as there are no user serviceable parts inside this tv as its solid state and all the parts are soldered in. Your problem could be a cold solder connection on the horizontal drive transformer, or a bad horizontal output transistor along with the HI-Voltage transformer. Like I said If you have no experience with tv sets, this repair should be handled by a pro. Good Luck
