what have you tried to do to fix it?
Sounds like the PSU is going into over current protect. If you had bad components on the PSU board there may still be other issues not found and repaired. Try replacing the PSU.
If you are sure the PSU is functioning correctly then you have a short or faulty component elsewhere.

check to see if the screen shows the outline of an SC code eg 202 or similar, a lot of the time you need to replace the laser polygon mirror motor befor repairing/replacing the board concerned, and possibly one other pcb, good luck.

Unplug connectors on psu one at a time to see if it recovers and narrow down the location of the problem.....
TV or electronics service centers generally know how to repair power supply board at good prices
