Turns on and then off
This issue is related to a power problem in as much as the receiver turns off on it's own.
The problem is consistent with overheating on the power supply board of
the receiver. it might have worked fine in the past, but that's
electronics for you. Power surge, irregular power supply, excess power
supply, etc can affect the unit thereby making it to misbehave.
The power supply board of the receiver has few capacitors and IC. If
any of these IC's gets short or become weak, it can cause the receiver
to turn off on it's own.
When current passes from electric outlet to the power supply board of
receiver. The current also goes to the weak/faulty part, then the
current stops or slow and the board overheats and receiver shuts off on
To solve this issue, check the power supply board and read it with a
meter and continuity tester, in order to detect the faulty part and
replace the faulty part on the board which is short due to which power
You can buy these capacitors at any Fry's or Radioshack store or you can
order them online at vendors like "mcmelectronics.com"(look for
electrolytic capacitors). After replacing these capacitor(capacitors)
most likely the normal operation will be restored. Or you can by a
refurbished complete power board from www.shopjimmy.com to save you some
If you don't have the ability to read the fault, then you might be
needing the help of a repairman or you can call a friend that has the
ability to help you out.
I wish you the best of luck.
