Re: Konka model 1508U 12 v dc ADAPRTER PORT
Most devices are Negative to Earth, Chassis and Positive to the Center Pin on the "Adapter". So probably any 12 - 14 Volt say 4Amp well regulated, or Switch Mode power Supply probably would power your unit..
If you don't know the exact voltage Start at about 6 Volts and work up until it works correctly.. I often use a switchable power Supply to find the right voltage and then get a fixed supply to suit.

I have a Sony Bravia 46'' TV. I bought a Universal WiFi Adapter from Walmart a few years ago for about $50. You have to plug it into the Ethernet port on the Bravia using an Ethernet cable (the other end of the Ethernet cable goes into the Ethernet port on the adapter). The adapter needs also a power outlet. I do not remember if the adapter came with the Ethernet cable (likely) or I had to buy it separately.
Before buying the adapter make sure that:
1. Your Bravia has an Ethernet port (on my Bravia it is in the back of the TV), and
2. You have/use a wireless router for your home network.
The M55 series does not output to external VGA automatically. You can either go into Setup (press F2 when computer is starting) or use FN F5 in Windows to toggle between LCD, monitor, or simultaneous output.
The monitor port should be standard, so as long as the plug on your monitor doesn't have any bent pins, it should work.
Your TV is a CRT as opposed to the more modern LCD type. Natively it doesn't have a VGA port that a more modern type would. So, in order to connect your laptop to it, you'll need to buy a converter. If I were you, I wouldn't do so because your TV is a CRT and it wouldn't look as nice or sharp as a computer monitor. You can get a 27" LCD on the cheap, so why not get a new TV instead?
If the printer does not have a USB port and the computer does not have a parallel port then you will need to get a USB to Parallel print adapter. One end is USB to plug into the computer and the other end has a standard parallel port to plug into the printer. Install instructions will come with the adapter. Try any computer shop such as Best Buy, Radio Shack, etc etc.
Your mac mini more than likely has a DVI plug on it for a monitor. You just need a DVI to VGA adapter. You can get them at any computer store for around $7. You can get them at best buy also, but for some reason their cables and adapters are way overpriced.
If you don't have a mac mini, then your connection will be different. If that is the case then I would need to know that model of your computer. Here is a link to a random picture of a DVI port:
