I got a sony trinitron over the last few months it takes a long time to switch on,sometimes up to 2 mins!. was wondering if you know wots wrong? thanks

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 ....it takes few mins ( in your case few hrs or days ---- very rare case ) for picture to appear...........so 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, [email protected]) ----- 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.....

I have a Sony Trinitron 32 color tv KV 2168MTJ (quite old - 10 yrs old), and the standby light blinks exactly 200 times (just over 3 mins) before it turns on. Once it is on, it works perfectly. What's wrong with it and how can i fix it?

Sony incorporates a video blanking circuit that blanks the picture out when the picture tube begins to get weak. sorry, but short of replacing the tube, there's no lasting solution to this problem. I used to have some success rejuvenating the crt, but I found that it didn't last but a few hours before the blanking circuit starts to activate again.

sounds like the tuner got hit by lighting. Cost of tuner unknown to me at this time have seen them from 20.00 to 100.00 dollars pluss shiping and then have to pay repair shop to put it in. You probley would be better off buying a new tv there is no telling what else could be damaged that would show up at a later time like in a few days to a month or so.

The Power Supply has gone. It needs replacing.

Check 470 uF 450 V in the power supply. I don't know if the chassis is the AE-5, but I had a similar case and the capacitor was bad.

Please tell me if it worked.

Hi: Sounds like it might be an overheating part, and the short is shutting of the set. Or it could be an intermittent connection in the pc board. Either case it would have to be repaired by a expert.
sorry.

Yes sure your tv can be fixed just call a tech and outline the problem.your tv has losted for a long time after repair it could last you a very long time congrats for keeping a tv for such a long time.

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
