Sansui AU-4900 Amp not working.

I recently picked up a 1977 Sansui AU-4900 amplifier in very good physical condition.
When plugged in the power light works but no sound comes out of the unit at all.
I was looking to see if anybody out there may have an idea what the problem could be or if there is a common issue with them?
I'm not sure if these models are worth spending money on and unfortunately technicians want about $50.00 just to open it up and have a look before they tell you it's too old and not worth fixing!
Thanks

Further to my original thread, it turns out the power supply isn't working. I have no technical knowlege when it comes to electronics. Can somebody please enlighten me what exactly this means, or what part needs replacing?

Hi Keiko;915891, it seems the cost to repair the amp is more than it's worth. A real pity considering it's in excellent condition. I saw it at a flea market and for $5.00 I couldn't leave behind. I'd truly like to hear how this amp would sound on my system, but I can't justify a minimium cost of $100.00, plus the caps and dry joints could also be another issue to deal with as well! Thanks for your reply and the links were helpful. I have no technical electronics knowledge and I was just attempting to find out what repairing the power supply actually meant. Cheers.Unfortunately, Sansui pulled out of the U. S. market back in the mid 80's. I still have some vintage units in storage somewhere around the house. I don't know how much you're willing to spend to resurrect this unit, or if it's worth it to you. Sansui made some good stuff at one time and I always enjoyed the sound of their equipment. Anyway, here's a couple links I found for you. Maybe one of these techs can help. Good luck.
