There are two basic methods which can help you deal with the glitch on DM500S.The first method can be used to find out the problem. It is the exclusive method. The exclusive method can be the best method to judge which unit on the electric equipment has glitch since it is easy to operate and requires less time than other methods. It works better if you have more objects in a system, whether they are Dreambox, 4 way DiSEqC switch, coaxial cable or TV set.
The Second method is the backup recovery. To make sure whether the problem of the electric equipment is result from the error of software, using the healthy backup to recovery the object is a good method. If the equipment works well under the healthy backup for it, the problem may happen on your plug Ė in or operating system. If the hardware still canít work, it must have something abnormal on its circuit board. Here we use these to method to fix some problem of DM500S.
1.#DM500S doesnít support the 4 way DiSEqC switch well. This is originally because the 4 way DiSEqC canít raise enough voltage to alter the channel. The problem may result from the following reasons: the quality of the 4 way DiSEqC switch, the quality of the 22 KHz switch attached to the 4 way DiSEqC switch, the difference between different types of LNB, there isnít enough power for LNB output by DM500, error of operating system or problems in usersí usage. Then we solve the problem by exclude the glitches listed above. If it is result from the quality of 4 way DiSEqC switch, we can replace is with a better one or move it indoor (some 4 way DiSEqC switches are sensitive to temperature and canít work under cold environment). The fix the second situation, we need to get a better 22 KHz switch to replace the former one. If something is wrong with the power supply circuit of DM500, we can replace the capacity on the circuit for larger on or use the more powerful AC adapter. Actually, this problem often happens when the SERVICE and SATELLITES file are error.
2.#Unable to turn down DM500S. The phenomenon of this problem is that the red light which indicates the machine is in the off status is on but there is still video and audio output. You can use the second method to fix this problem since it usually happens when the decoding software is error.
