2 failed multiswitches in 4 days? Help?

06-14-2005, 10:03 AM
Hi. I went HDTV about 2 weeks ago. I went out and got the triple LNB oval dish and a Dynex 5x8 multiswitch. It worked great for 2 days, then it was dead.

So, I bought a Terk 5x8. Worked great for a day and a 1/2, then my normal satellite feed went dead and all I get are HD channels.

Both Multiswitches ran very hot... so hot a 5 second touch would hurt.

Anyone have this issue? I'm about to go exchange for a 3rd multiswitch. All my sat signals are in the 90 percent range, but no picture on non hd channels in all rooms.

Any help is extremely appreciated.

I've come to a possible conclusion that the multiswitch is burning out, but I can't figure out why. What are the odds of getting 2 bum multiswitches in 4 days?

I'm not an expert but I know who is. Go to this blog written by none other than the High Def Forum's rbinck. pay close attention to the voltage parts.

Thats just how to wire it, which I've done correctly. I'm going to try a monster cable surge protector to see if it's my electrical outlet sending surges to the multiswitch. If that doesn't work, I'm clueless.

The receivers provide the +13/+18 to the switch when passes it on to the LNB. A fault in a receiver, a short in a cable ( causing more current? ), surges and of course a bad second switch are the only things that I can think would cause this type of problem. Good luck!

A 3rd failed today. This one didn't get the HD channels from the get go. So, I decided to take a direct line feed from the dish to my HD, then I hooked back up my 3x4 non powered TERK for my other non-hd feeds in the house.

This still leaves me with 2 expansions (1 HD direct from the dish and 1 non HD from the TERK) for the future. I'm done messing with the 5x8..... it's obvious I have too much surge coming in my basement outlet and I'm not in the mood to call an electrician.

If I so desire to get more HD sets, I think it will be cheaper and easier for me to just mount a 2nd dish on my roof and just not mess with it.

Buy a UPS, costs $100-150... power is completely regenerated in a UPS, it stops surges AND props up brownouts...

But, beyond your supply current, you problem probably lies in your STB... this is where the power for the multiswitch comes from, and yours seems WAY too high.
