iandmills:
standby light on wont switch on can anyone help

mulja:
Need more information as to what you have checked etc.

iandmills:
the 3 and 5 volt lines are present the 15 volt line is also present but it does not discharge after the supply is removed 1 hour after the supply is removed 15 volts is still there.

iandmills:
it also says on the back of the  set rz-15la70 rev a

mulja:
Check the voltage on base of Q701 and press the standby button and see if the voltage changes. If it changes you should have -15v, +15v, +12v, 3.3v and 5.5v. If this happens then your power supply and microprocessor are ok the set is coming out of standby and your fault lies elsewere.
