They can vary depending on if it has PFC or not but most CTR sets didn't have that, I would look for 165+ that comes from line voltage divided buy .717, if it has PFC then it can get up to close to 350, generally the main filters give an idea of what the voltage should be, figure filter rating x .80. Remember on the hot side of the transformer use floating ground on the cold side frame ground when you measure.
Testimonial: "Actually I confused about out put voltage of SMPS from one pin to gnd 125V dc which is correct but from otrhe pin to gnd get only 9v dc I think it should be 16V dc atleat since filret capacitor reting 25V 2200MFD.Used SRT is 5Q0765RT what is the problem?"

try to check its high voltage section for axed HOT or flyback. Also check its regulator. Maybe start up resistor or check the chopper circuit. You should at least have an standby voltage on the secondary side.

If the power supply has failed then you must check the SMPS unit. The diodes from the secondary sides must be checked including the zener diodes. please check the link below for tips on SMPS service. http://www.fixya.com/support/r5826301-working_switch_mode_power_supplies

Have you tried to unplug the set from power for a while and then replug to see if it reboots?
