I have a ten year old 37" Sony XBR TV that works fine until you turn it off and then go to turn it back on. The picture does not come back, but sound does. The only way to solve this is leave it off...


most likely it needs repiars, (replacement of capacitors in the power-supply.)primary and secondary side.
Or loose conections (dry joints)

Sony Trinitron color TV model no. kv-27v22


dear, you can check that transformers out put before connecting to a tv. also when its connected to a tv.
get a avo meter and connect in series with a tv.
observe the current on the intial switch on and when the picture goes. if you notice that current on intial switching is high and then it starts going lower and lower, then change the transformer.
but if the current starts going up from the intial current then check the power supply components of the tv.
thanks for asking fixya.
