It sounds like you have a problem in the power supply or a short somewhere in the unit which is causing the power supply to stay in the standby mode to protect it. You say that it won't start with the remote, and I know this is simple, but it certainly would not hurt to try the controls on the unit, just in case the remote or pickup has a problem. If that doesn't work and you have repair skills, know how to use a DMM and check transistors, as well as knowledge of TV safety issues, you will have to troubleshoot the unit. This could be a shorted horizontal output transistor, a bad power supply or a short somewhere else in the unit. If the HOT checks bad I would replace the transistor and flyback and check all the associated components for any problems. If you find the HOT bad, that is probably your problem. If the HOT checks good, you may be beyond your skills and need to have the unit looked at by a qualified tech. That's your call. Good luck.
