Help with 301-010

[gamb]

i have a 301-010 that only receives 105! coax checks above 18v! my other two receivers work fine!(119,110,and 105) any help would be appreciated! THANKS

Try on remote menu,6,1,1 see if it shows your multiswitch if not select and run the check switch then see if it shows all the sats, If it still doesn't work the eeprom is the next to redo this is where the switch info gets stored and can get corrupted.
there is more but not alot of info in your post so starting with the basics.

thanks i will try epm. switch will only find 105! other irds work fine.

Which LNB's are you using? If switch Check does not show them you prolly need a Dish Pro adaptor for your 301.010.

No...., a 301-010 is a DP receiver, no adapter needed.

i am using a superdish w/dp34! as i have said 2-3 times,my other irds are working fine on same system including the cable! volts are down to less than 10.
thanks

Can you hook the -010 to a feed before the DP34?? see if it detescts the 110/119 sats??
The sat tuner chip in the 010 is suspect, they fail fairly often.

I was thinking that he had the early LNB's which would work with his other IRD's, but not the 301 IRD which needs DP LNB's.

Nothing NEEDS DP lnbs.
All receivers run fine on legacy lnbs.
Only restriction is if you have DP lnbs you need a DP receiver OR a DP adapter.

[gamb]

why does the other two 301s work,if it needs different lnbs?

If your lnb voltage is 10dc or lower now you have ird problems, Sounds like you have a meter pull the cover and check voltage on tr31 pins 1,2 and 3 meter red lead on one transistor pin at a time and the black lead on the tuner metal cover for the ground connection. Post your readings then. This is a booby trap unneeded circuit so the tsop can turn off the lnb power and this circuit likes to cause problems. It can be bypassed by shorting tr31 pins 2 and 3 togehter without hurting the ird in any way. If this is the case pin 1 and 3 will read low and pin 2 will show the correct lnb voltage. The lnb 13-18 volt control circuit is back farther in the power supply area this circuit has nothing to do with odd/even lnb voltage, Just a lnb voltage cutoff is all this is.

voltage on tr31: 1-46 2-49 3-42 thanks (rt. to left)

Make sure meter is on DC volts and you are reading it correctly, Those voltages are nowhere near what they should be, Nothing over 20 volts dc. If it's a anolog meter make sure you are reading the correct scale on the meter, If it is a digital readout make sure the battery in it is good, Some give crazy readings when the bat is weak.

[BirdieMod]

Also try this, Unplug the ird ac power now and meter for continuity ( Like checking a fuse ) between tr 31 pin 3 and the lnb sat in connector center pin, Should show a very low resistance here. The trace between these two points is very small and sometimes can burn or open.

any chance someone modded this or put wrong build on

[gamb]

have tried 20 dif. builds even orginal 6 times,thanks.

[Bandit5906]

There must be something that you may be doing wrong.

Why not in one post relate your complete problem and then what you have done, step by step to help us help you out?

[BirdieMod]

It holds sat 105 good though, No signal problems? That shows the max chip is good most likely unless the 22khz isn't working to tell the switch to switch but never ran into that one yet. Your readings look fine now.
Have you tried unhooking the sat cable all together and running check switch then, It should change to nothing found then hook it up again and see if it at least detects the correct switch model.

[BirdieMod]

You know after thinking I have ran into a freak problem a few times with the receivers sat in jack center connection getting worn too big, RG6 and RG56 cables have a larger center wire, If these were used alot and then a rg 59 cable after which has a smaller center wire sometimes the connection is not very good then causing weird intermitant issues.

[Bandit5906]

Man, you are thinking outside the box! I would never have thought of that even though I did run into the same thing once when switching from Dave to Charlie and not being carefull with what I was using with both of them: too many dishes, switches and crap everywhere. Those were the days!
