Sir try to check first the cables connecting to your tv if you are using a digital receiver, specially the video cable on the receiver going to your tv. Good day and best regards.

Help!!! my litmann 4000 wont turn on even with new batteries!!:(:( any ideas usually after fiddling with it then it work but not this time and i need it!

Hi,the problem is obviously from the internal battery contact of your device,or a the cord that delivers power to the unit is broken,you can take apart the stethoscope and fix it,but as a warning,the litmann 4000 is a very fragile and sensitive electronic stethoscope that requires high technique and expertise to fix,so i will suggest you contact a qualified stethoscope technician,so you don't end up ruining your stethoscope.

Thanks and take care

There is no sound coming from the ear of my stethoscope. Do you have any suggestions?

First try new ear buds...they do get clogged just like ears! Next, replace gets dry and will get fine cracks that are to even notice unless you are looking for them Littmann tubing does not contain does need to be conditioned with Armoral. I just found that out...after using mine for 7 years! OR>>>>buy a new one !!!!

After making my post, I went to the official Brothers website for the 4100 FAQs and "Operating Instructions." Here's what I found. Set your 4100 set to the "Fax/Tel" mode. Press "Menu", then the number 2 (Fax), then number 1(Set-up Receive), then number 1 again (Ring Delay). Use right arrow key to increase. Once increased, press the "Set" key. You'll see the message "Accepted." Now press the "Stop" key to exit "Menu." This will now give you up to 4 rings before the fax auto answers. Inorder to send a signal by phone to remote start the fax just follow the instructions I copied directly from Brothers instructions for the 4100: If you answer the call on an extension phone (this is any phone plug into a phone jack on the same line) and hear a beep every 3 seconds (automatic fax) or just silence (manual fax), press *51(remote activation code) on the telephone keypad, wait to hear the Brother machine turn on (chirping sounds) and then hang up. I don't have anyone that can send me a fax right now to test it out. I'll have to try it in the morning. Hope this works for you.

Samsung scx 4100 cleaning the roller

one way to clean those rollers is to take the printer apart. this would provide you with enough room to fix it and clean it.

however, if the suggestion of taking it apart does not sound good, you can still actually have that cleaned while it is turned on. as what you mentioned, you are asking how would it turn while cleaning it. i suggest that you try using the qtip and tune the printer to turned on. so that you can actually see what your doing with the roller.
