Sennheiser SK 100 Bodypack Transmitter won't power up.
I have a SK 100 . I used it with noproblem Thurs. night and turned it off . Then went to perform Sun. mornand all I got when I put a new battery in it was the red on/low Batt light. Nothing happens when I press the red power button. Nothing appears on the screen. I tried several newalkaline batteries and one the rechargeable we use in our wireless handhelds. Any ideas why?

Hello. I Am Not Familiar With This Exact Model, But I Have And Still Do Own A Number Of Wireless Units. There Are A Number Of Things That Can Go Wrong, But If The Unit Wont Power Up, I Would First Check The Battery Compartment For Loose Battery Connections. Over Time They Can Weaken Or Just Get Bent The Wrong Way. Then I Would Look For Loose/Unsoldered Wiring. I Have Encountered Many Cases Where The Battery Compartment Contacts Become Loose , Or The Wiring Going To It. Good Luck

"Feedback" might have been intermodulation with another RF frequency. Make sure to use Sennheiser's frequency finder, or something similar, to determine what TV channels are clear. If you're using more than one transmitter, make sure they're all using the same channel bank.
The low bat/on indicator should be on solid if battery is good; and flashing if the battery is low.
The Shure body packs will only last so long before needing repair. You can contact Shure and have them refurbished for about 90 dollars a piece. It will take about a week once they receive it. I am very familiar with Shure as they are my go to brand for all of my installs. If you would like assistance, information or pricing on replacements let me know. These can be fixed though.
Phantom power is used for microphones with "built-in" electronics. These mic's, receive a DC voltage through the mic cable that powers the internal electronics. I have never ran into wireless microphones that require Phanto power, so I will assume that your wireless problem(s) is being caused by something else. http://en.wikipedia.org/wiki/Phantom_power
Sorry, that will not work. Typically, it is not possible to use one manufacturers transmitter with another manufacturers receiver. The two manufacturers use different tone-key squelch, different noise reduction, and different companding schemes.
Audio Technica and Sennheiser each have proprietary connectors for their mics. A lot of times the mics require Phantom power which is drawn from the battery of the pack.This is important as the mic will need to be wired correctly to function. The first thing you will need is the correct plug from the company. Check with Sennheiser customer Support for the correct part. If you aren't extremely good at soldering, do not attempt this. You can change the plug but the wires are extremely delicate and can short easily. Moreover because of the phantom power, the plug must be wired correctly for the mic to function, or you may end up damaging the mic by sending phantom power up the wrong line. I would advise having a music store or pro audio service that handles these products do the wiring for you. If you feel you are up to it, you can do it yourself, but be careful.
It sounds like the solder joints on the circuit board in the body pack are starting to fail or the switch is starting to fail. If you don't want to fix this yourself or it is still under warranty you might be better off taking it back to the dealer to have it replaced or repaired.
I regularly use G2 ew100+300 systems, which have a manual squelch adjustment on the reciever. Squelch is difficult to explain but here we go: a squelch adjustment gives you the options LOW, MEDIUM, HIGH these settings effect transmission distance and interference rejection. for example: a HIGH squelch is less prone to interference but has a shorter transmittion distance. A LOW squelch is more prone to interferance but allows for a longer transmission distance. For most applications, a MID squelch is fine. If this does not help- the next option would be to swap arials between units and see if the problem moves. The G2 series are a 30mw transmittion which has an effective range of about 50m
hope this helps.
No worries, thanks for getting back to me. Another questions for you. What sort of batteries are you using. Are they rechargeable, alkaline, carbon zinc, or the Sennheiser BA 2015 accupack rechargeable.
