I have two LNB's from one dish which havwe 4 cables running into a switch. From this switch there are 4 cables supplying signal for my HD tv (2 cables) and two regular tvs (1 cable each) My problem now is trrying to supply a signal to a 3rd reg TV Can this be done with a splitter of some kind?

Three things here the unit the cable or the LNB.
Simple things first Cable
Check the satellite plugs on Both ends are correctly fitted and there is no shorting of the core central cable and the shield. Check the cable with a meter put a loop( connect core to shield at one end) on the other end and check resistance.
Check your unit with a know good setup a friends perhaps.
3. LNB the unit on the arm of the dish
You should be able to get a signal from the LNB with a alignment meter. or replace with known good to test
That's great to hear that you've been provided the appropriate
resolution for the issue you've experienced and I do apologize for the
delay! If you need help with anything else, please let me know so that I
may provide further assistance. My email address is firstname.lastname@example.org and I hope you enjoy your service!
If you can monitor the supply to the LNB, you may find it is low, unplugging it when the decoder is powered up allows for more power. I would change the power supply capacitors if more than a couple of years old.
How many coax cables are you using from your dish, 1 or 2? Do you have a switch between the dish and receivers? I am assuming your have a 1000.2 dish since you say you have the 129, 119, 110. On the LNB you have 4 coax ports. Facing the LNB, the port on the far left is for 119, the next is 110, then 129, and that last on the far right is for an additional dish. If you want to get 119 and 110, just use the 2 ports on the left. Once connected, run your check switch. I hope this helps.
Ok since you have A 625 it uses different technology than the 4000 in a sense but I will assume that whomever connected the 625 use a Dish Pro Plus LNB. You can verify this by going out to the dish and looking at the LNB which is the eyes if you will on the dish. The cover facing you will read DP Plus, or Dish Pro, Dish Network, or you may have nothing at all on the housing. You will want it to say DP Plus for the easiest install. On this LNB there are three ports. You will only need the two on the left if looking at it so you can not read the housing. One of the ports will be connected to a line running to the 625 and the other to the 4000. The line going to the 4000 should not contain any breaks in it after the ground block if one was used. Once inside the house connect the line from the lnb for the 4000 to the back of the receiver. Conect the receiver to the TV and run a check switch. This receiver will go into a test of 1 of 38 if all connections are good. A 1 of 50 indicates a loss of signal somewher on that side of the install.
The 625 can utilize di plexers but that type of install is to detailed to go into straight away so we will connect it using a straight feed to TV2. Run the cable from the LNB into th room with the 625. Inside connect that line to a siver device called a seperator that came with the receiver and connect the two leads from it to the sat in ports on the back of the receiver. Connect a line to the Home distribution port on the back of the receiver and run it to the room with the second tv you want to have DVR in such as a mater bedroom etc.Connect the cable from the tv out port on the receiver to the tv. Power all devices on and run a check switch. This test should read 1 of 3 if all connections are good. A bad connection will read 1 of 38 on the receiver. A total absence of signal will stay at 1 of 1 for a longt ime brfore going to 1 of 38.
You will need to call dish and activate the 4000 rx since it has not been on the account for some time and will need a software update that they will send to it via satellite.
Other obstacles could arise and if they do let me know. Thanks for using Fix Ya.
You will need a DP or Legacy twin or quad, or DPP twin without using an external switch. If you use Legacy Duals, or DP Duals you will need a switch. USUALLY a SW21 is used to combine the signals but you may have a different one in use if at all.
The primary thing to remember when using a switch is that you must use the same type of LNB as switch e.g. Legacy switches with Legacy LNB's and Dish Pro switches with Dish Pro LNB's.
Check your LNB type. Legacy LNB's have only a Dish Network Logo on them, Dish Pro has DP on them and DPP have DP PLUS on them.
One of three things could be the cause:
1. Line of site. Must be clear of all obstructions to ensure adequate signal.
2. You have a faulty switch, or conflicting LNB and switch, or no switch at all.
3 you may have a bad port on the LNB.
As a fail safe check that your mount is level and plumb. You also may have the dish pointed directly at 119. Check the Skew and elevation settings as well. If LOS IS THE ISSUE YOU MAY NEED TO RELOCATE THE DISH OR REMOVE THE OBSTRUCTION.
In some extreme cases microwave towers and High Voltage lines also pose a problem but doubt this is the case for you.
There might few possibilities:
Loose cable from the receiver to the diplexers, switches and LNB.
I would suggest to try swapping the receivers to isolate the possibility that one the receivers might defective as well.
Hope this helps.
I looks like you are picking 110W with the LNB on your left if you are facing the dish.
Try to get 119W first if you connect the cable to the 119 LNB, once you find 119W that way, you will also have 110W.
