20 Most Recent Sony BM-815 / BM815 Micro Cassette Transcriber Questions & Answers

I have the 3 of these units at my office with the exact same problem. Turns out, with a little tinkering there is a simple fix.Open up the unit (by unscrewing the two screws underneath) and look for a brass disk with a black rubber band around it that connects to a small tip. The rubber band should be either stretched, broken, or even melted. This is the problem. Over time the rubber band deteriorates which causes the unit to not play a tape (rewind and fast forward operate differently). Replace the deteriorated rubber band with a new one similar in thickness and size. That should work like a charm. Be careful if the original rubber band has melted. It is tar-like and it will be difficult to remove.Hope this helps.

Here's a GREAT idea! BECAUSE this is such a nice but older Sony... "I" would use a Blu-Tooth SPEAKER with a AUX speaker input! LOTS of AUDIO and VERY inexpensive too! OR I recently bought a BlueTooth TRANSMITTER/RECEIVER that has a 3.5mm" Jack right from it's body! Depending on the 'mode' it's in ~ it will TRANSMIT audio (like from your Sony) to a Bluetooth Speaker! (In it's second mode it acts like a BT RECEIVER.) Here's a official title of another: Mini Bluetooth 3.5mm Music Audio AUX Wireless Transmitter eBay: 322589063752 and it's about $7! This puppy is a Bluetooth TRANSMITTER only. "This device can transmit music from your media devices(smart phone, iPad, mp3, CD/DVD player , TVs and more) to your Bluetooth-enabled equipment (bluetooth speakers/Bluetooth headphone, etc) simultaneously" THEN there are THESE "3 Watt" BLUETOOTH RECEIVERS for UNDER $2 ! I KNOW! Hey man ~ just pick your color! eBay: 112673621308 DANG ~ I'm going to order some now! MMMmmm try earphones? How is the volume then? Plenty? ALSO earphone jacks become dirty and the contacts that SWITCH THE SPEAKER OFF become poor conductors that starve the speaker for volume... anything more than this MAY constitute a MAJOR repair cost... SO KEEP your SONY and consider the options! ANTHONY

hi Karan. as its already been asked by Anthony Cardenas,it would have helped if you had of said what model. but this is all i could find out. Try another USB cable. If that doesn't work then the headphones may be faulty. Do they have easily replaceable batteries? It's worth finding out if the batteries can be changed I had the same problem with mine, I'd not used them for a few weeks and they wouldn't charge. At least thats what I though. Try leaving them on charge on the PS3 for a few hours regardless of charging light. Also try pluging them into a PC with the wireless dongle, you're PC should recognise them as speakers and mic, if that works at least you know the headset is fine. like i said this is all i could find on the internet so not sure if its any help to you,if not sorry for taking up your time,and i hope someone does get to help you out with this. or see if this link helps you out. Ps3 wireless stereo headset wont charge Google Search

not a radio communications issue

Your ruizu has no bluetooth or is faulty .
