If the green light is not lighting up, you will need to check out the standby power supply inside the TV set, or if this set has a DM board, you will need to change the capacitors. Good Luck

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Most common death mode)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!

There are not many things that audio and video have in common and the power supply section is most likely at fault.
If the system has an LED indicator and it isn't lit, the supply is probably the reason.
This is not a good place for users to troubleshoot and can be dangerous, even after the power has been off for an hour or two.

Check the display IC module for burst or bulged capacitors. If found any, they should be replaced with the ones with exactly the same specifications. You may also find some wax if the capacitor has burst or leaked.

Take a look at CR4118, and the capacitors around the power supply
regulator chip. You likely have capacitors that are dried out. They
can take out the chip, and Q4101, the 'chopper'.
The web site: http://eserivceinfo.com/ has a program for the CTC169 series of RCA projo's that is very useful in finding the fault that causes the condition you describe. Just enter ctc169 into the search box. Or go to this URL:
