Does anyone have access to this service manual? My receiver constantly goes into protect (POWER OFF) mode when turned on. I would like to replace some transistors and resistors to repair the unit.

|02-07-2015||1) I thought Radio Shack went the way of the Pony Express, telegraph, Edsel, etc.
2) There are two basic types of fuses available for appliances and consumer electronics: fast-acting or time-delay. Any replacement fuse must match the one itís replacing. |

|02-07-2015||thanks jts1957... umm can you be more specific? do you mean measure the transformer while the unit is plugged into mains? sorry i just have a basic understanding of electronics and a cheap volt meter from harbor freight :D|
|02-07-2015||I'm presuming the 6800ufd capacitors involved are discharged and that your meter is a auto-ranging digital-type and that you have read its operating instructions.
Since the relay clicks when you try to power ON, Standby power is working.
Since the fus|

|02-07-2015||thanks jts. actually i think i misspoke. the fuse actually blows out as soon as i plug in the unit to mains. maybe it wouldn't if i put in a time-delay fuse instead?
and i'm not sure i'm equipped to measure across those first two big capacitors (C70|
|02-07-2015||Unless relay contacts are 'welded' together or relay energizes just for an instant - 'was last ON' memory), Mains can't get to FU1 (#53).
You DO have the SM. You may measure between the metal chassis and ANY point that the positive pin of each capacito|
|02-07-2015||what square is D701 in, in the complex assembly diagram?
yes i have a soldering iron and know how to use it... they actually have some components soldered to the chassis so i will need to desolder those to even remove the circuit board :P|

When the time comes ...
Most open like a book, provided you can create enough slack. Mark screws/holes so that the right one goes back where it came from. Take back off ("38"), remove screw from regulator, remove 2 screws |

|02-07-2015||ah you were talking about this part?
it's the only part that's not freaking labelled! :x|
Can you 'float' the primary of T1 (disconnect pin 1 or pin 4) and install a good fuse and see if it blows when first plugged into Mains? Also does pressing the power button actuate the relay on [b:e432ebb0ef][u:e432ebb0ef]&[/u:e432ebb0ef|
|02-07-2015||i'm not sure how to do that... all the wires are soldered in pretty tight... i guess i could try desoldering pin 1 on the multi-conductor wire where it connects to the Trans Assembly (43)?|
