marantz sr4002 with fast blinking standby light - all else

marantz sr4002 with fast blinking standby light - all else dead? Glass fuse inside unit is ok.
The unit is in "protect" mode thats why you are getting blinking standby light . This means that there is a problem in the final output section. The most common fault is bad output transistors. Expect a parts cost of abput $15-$30 in parts plus the local labor rate for a repair cost.

first you will ahve to restore the prtective circuit, as its protecting the other important circuits.

What is involved with restoring the protective circuit??
protective circuit is nothing but a circuit which protects the other main parts of the Circuit.
If some problem in the main circuit , will be handled by the protective circuit.
IF something got screwed in the main board then the TV swap the mode to protective or Stand by.

in this state , the main circuit will be safe from further damages.

First you will ahve to check the possibe damage to the trasnsitos/capacitos/resistors.

once you corrected the problem , mode will be chenged to normal and you can see the video.

its better to call a proffessional to get this done.

while doing that, check the protective circuit also , because it got screwed means evrything will be damaged soon or later.
