Sony Trinitron experiences

My Sony Trinitron was manufactured in 1998. For the last couple of days, every minute or two, the picture goes black for 2 to 3 seconds, then comes back again. Since it is 9 years old, I dont want to invest a lot of money in it if it is something major like the picture tube, but I expected a TV that cost as much as this one is to last longer than 8 or 9 years.

My Serial number says it si a Sony Trinitron WEGA KV-36FV1. Any ideas?

Re: Sony Trinitron experiences

The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

I turn my sony trinitron off. when turn it back on it will not turn it will not come on for hours and sometimes a couple of a couple of days!

I HOPE AFTER FEW MINS OR HOURS OR DAYS when your TV gets on & picture comes then everything works normally atleast for few mins...then following is the situation.......after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is takes few mins ( in your case few hrs or days ---- very rare case ) for picture to solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV ) ----------iam from bangalore (09986222774, ----- here EHT's price will be around US $ 10 & for my customers (in bangalore) i will take another US $ 12 as sevice charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer or sony service centre ------- because they are highly experienced & can fix this component very easily.....

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 flickers off and on

I would try adjusting the screen control on the flyback. The flyback can be easly located, find the red wire attached to the top of the picture tube & follow it down to the flyback. on the flyback you should find two controls, one screen & one focus. you sould be able to read the words above each control, only adjust the screen one. slightly increase the control till the picture stays on, if you turn it too much you will get small white lines going across the screen. Now if what i have told you fixes the set, then it is only a tempoary repair. could last days or mothes, maybe years. if it starts to happen again later the set will have to be replaced. this is a sign of the picture tube starting to get a weak. ALSO DO NOT PLAY WITH THE RED WIRE IT CARRES VERY HIGH VOLTAGES EVEN WHAN UNPLUGGED FOR DAYS.
