You haven't given the exact model number to your TV here. Back light inverter might also replaced along with defective CCFL lamp/s. It wont cost more. Anyway will cost around 10% of the total cost of the TV
SOURCE: Sony Trinitron Model KV-27S10
If hte set is a Sony, the standby light should be blinking a code. Report that code here and we should be able to guide you. That code will indicate the problem circuit within the set that has the fault.
Thanks,

SOURCE: flatline!
the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.
SOURCE: My Sony trinitron tube Tv 36" seems to be going (its 10 years old
no ....the tube will end up after 20 yrs in 10 yr old sony...
it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone
then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..
Testimonial: "Great response... I basically needed to know if it is worth fixing (if its the tube) I like this tv and don't want to ditch for a new flat screen. thx"
