Anyone have a schematic for an SAE R-102 receiver? i have one that someone mucked up the tuner section and a couple resistors burned, transistors shorted that dont look like the right ones, etc....

Spoiler alert: I am a total noob at this, just getting into the hobby
My buddy has an audio receiver that stopped worked, everything turns on and functions but no sound comes out of any output (Speaker, AV, or Headphone) So I said I would take a look at it. I popped the cover off, and saw an obvious issue: One of the resistors on the board had burned up.

Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
I can hear Fred Sanford now...."YOU BIG DUMMY".....I pulled the "F" connector out of the tuner by accident. The tuner number is BN40-00248B. Low and behold I had a scrap board with tuner number BN40-00248A. Although the tuner is different (according to Encompass.com) it's footprint on the board is exactly the same as the 248B so I decided to de-solder the tuner off the scrap board to see what I was getting in to.
As you can see in the picture the terminals and solder pads are super small. No matter what I tried I could not get either the terminals or support... -
Hello Everyone,
I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.
Symptoms:- Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
- Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
- I swapped the Left and Right surround

hi i have a receiver that is destroyed from the overvoltage i guess
my question is has three wires u v w for driving a motor fan i found an other receiver wireless from aliexpresss with the same propertiew but for dc motor
the motor fan has not label
i have an other receiver operational
In your opinion can i measure the voltage at the output ?
what do you suggest me with a simple instrument multimeter or using someone instrument more specific ?
thanks in advance...
