Re: Marshall Stanmore Repair




Sorry for the long delay.

Marshall had me send the speaker here:
38152 2nd Ave
Squamish BC
V8B0C4 Canada
8445671464

If I recall correctly, this cost me about $65 to ship both ways.

They replaced the entire main PCB. I asked if they could offer any information on what part was defective, or if I could even have the defective board shipped back, but they said that was not possible....

Re: Samsung Plasma TV Vertical Lines

Unfortunately, chrismurphy's repair was unsuccessful. Power supply wouldn't even power up most of the time. I'm just curious if this is the fault of the IC components hidden under the glued flat ribbon cables on the bottom boards, or if it is a faulty control board.

Re: Samsung Plasma TV Vertical Lines

Hi rofflesaur, I have this exact same issue on a Samsung pn51e550d1f Plasma I just purchased for $20.

I have cleaned all ribbon cable connections with %100 IPA and tried gently applying pressure on each of the bottom board permanently attached flat ribbon cables to no avail.

I will now attempt chrismurphy's repair (with set unplugged, thanks tvtimmy :P)

Re: Marshall Stanmore Repair

Hi all,

So I received the replacement IC chip (MC34063API) and after a long and arduous effort to solder this larger thru hole component onto a surface mount board, the original intermittent bluetooth problem persisted...

I have already sent the speaker to the authorized Marshall repair shop out of province for $35 CAD to get it fixed.
Hopefully they don't have an issue with the fact that I have a jumper wire from one of the IC pins to the connecting smd capacitor as the damn pin track came off as soon as I touched...

Re: Marshall Stanmore Repair

Also, if anyone has had success swapping out the 8-pin surface mount DIP MC34063A who was experiencing my issues (Case#1, Bluetooth connecting but no sound), I would be very grateful if you could try to guide me in how to check the voltage on the part, and anything I need to be aware of when replacing. I have a basic multimeter, and an OK soldering iron kit. My experience is beginner in the electronics field, I've successfully swapped out a damaged micro USB port on a Logitech Bluetooth speaker, so I have confidence in my soldering abilities.

Re: Marshall Stanmore Repair

Hello, I purchased a used Stanmore (1st edition) and while the unit turns on, LEDs working, Bluetooth connecting and staying a solid red LED, the sound will turn off when switching media apps (playing music, then playing a YouTube video, then back to music). The issue is very odd, as sometimes when I unpair and re-connect to Bluetooth, music will play, and sometimes it won't at all no matter how many times I try to unpair, unplug, and reconnect...

Speaker works just fine when connected to AUX... I have been able to replicate these no-sound...
