Hey I have a Phillips micro theatre mcd718..an I put dvds in an it doesn't play but the radio an other stuff works on it fine...

wrong country or codec

Its really a software type problem i have a sony hometheatre that wont play certain videos. When tvs/home theatres are made they get whatever software that is put in witch most videos require the basic stuff sometimes its outdated or just not compatable.

I would recommend resetting the Rosen unit. This is done by entering the "Menu" and pressing "Settings". From this screen, you select "Keypad" in the top right corner of the screen and then enter "7-5-2-3" and press "Enter". This should erase any code for Parental Control (levels 0 - 8). Also, the Rosen product states to only use "Store bought media" for CD's and DVD's meaning that it won't play all 'burned' discs. Hope this helps.- Elliot

Without more data, I can only make some general suggestions.

First: Check your cables. If you are using a converter box, there must be a set of audio and video cables going from the cable box to the Home Theatre unit. These will be a yellow/white/red set of cables. Second: If these cables are plugged into "AUX1" or "AUX2" make sure this is what reads on the front of the HT unit. You already have cables going from the HT to the TV because your DVD works.

Although this sounds obvious (please forgive me-I am not underestimating you) IF your TV receiver is 6 years old or more, and you are NOT using cable or satellite, there will be nothing for your set to pick up since the conversion from analog to digital.

You might try plugging it back into your computer, and formatting it. If you don't know how to do that, pull up the screen right BEFORE you would open it to copy music to it, right click on the flash drive, and click format. Format it with whatever the default format is shown (probably FAT32) and then copy your music back onto it. If that doesn't work, let me know.

sound like the center channel is out
either bad connection at speaker or receiver is not putting out sound on center. A quick swap of speakers at receiver end will tell you if it is the latter

possibly a ground issue , do you have everything plugged into a line conditioning power strip? are your speaker wire,s plugged into the red and black speaker connectors propperly,and are the positive and negative wires in the right order? also check that the component or hdmi cables are not the issue , but usually the buzzing noise would sound more like a ground issue , I hope i was able to help you solve your issue if not feel free to contact me again so we can tackle this issue together , if i was able to help you pleace leave a nice review ,thanks alot ,Sincerely glenn mayer

to play discs from different regions on HTS3548:

Before you begin, ensure you have connected your DVD player to your TV and both have the power on. Once you have connected the TV, follow the instructions below.

-- Open the disc tray
-- On the remote control, press in sequence:
Disc Menu
Stop
7 3 4 4 6 6 0
OK
-- Make sure Region 0 is showing on the TV.

This should hopefully help!!!!

did you put the firmware update, perhaps it can solve the problem

Your pickup is bad. Take it to a servicer for replacement or try to find one online.
