4DTV Help Support Guides 

First: Unplug receiver power.  Wait a few minutes. Reconnect power.  This will resolve many problems not listed.  Proceed with trouble shooting guide. If problem persists after reboot, try software-reset by pressing 6,0,5,<,<   If receiver isn't working normally, See list of Hints

Guide Changes

Recently the channel guide update has changed satellites to G1-100 (or ch 3) Also use channel 7 for database build and IPG guide.

Loss of Picture - Breakup

Enter installation-menu with Options 6, 4, 4, then enter.  Use autotune features first #3 Auto tunedish  #5 Autoskew, wait several seconds, each entry.   Quality should be higher than 28 or pixel breakup will occur. Easier to tune an analog channel first with misadjusted sats - procedure below

G1 Guide updates - Tips

Turn Receiver off when not in use, especially in the morning hours when new ipg guide info occurs.  In the installation-menu, the Dish move has to be checked or receiver will not move to get new guide data.  Menu prompts you to G-1 command when any new info is requested. Use channel G1-3 or channel 100 for updates.

Sat Missing in Menu - Remap Procedure

Go to G0 channel 5,  push option 6-7-7-8 then "enter" in manual tune--at the frequency box enter the numbers 1-3-1-0-0-0-0 so that the frequency reads 1310.000Mhz. Then push the down arrow and highlight the word "tune" and push enter. The word will change to "tuning". In a short time  quality number appears in lower right of the menu. If not, push tune again and wait a few minutes for quality number.  Wait 5 minutes for Sat Remapping. Hit exit (or view) button for normal. Missing Satellite should be back in the program satellite menu. Reinstall if unchecked. If G-1 is missing with DSR 922 then follow this procedure. Goto G1-150 then, unplug receiver power for thrity minutes. After initialization, G-0 should be back in menu, if not goto options 6,4,4, enter and reselect unchecked g-0 and retune as necessary.

No Satellite Function

No Sat function on two or more satellites, usually adjacent to each other caused by corrupted data in memory.  Remove power for two minutes.  Reboot will usually fix problem. Reinsert Power.

Satellite Missing

Use the analog adjustment (set channel on 1-24) then, by pushing the arrow  buttons on remote  move left or right to locate sat. Tune for best picture; enter to store (tune the dish position only) adjust until you find  missing satellite.

Reset-Menu

Warning options 6,7,7, 8 will erase all to factory settings (complete reprograming required) See special-menu-section   for other settings.  Some DSR922 Receivers from the factory have EMM provider pointed to 0001 instead of 0000 Use options 6,7,7, 8,0   The 0 clears EMM provider so that your programmer can rehit the unit. See Special menu section

Password Overide

Forget your password?  Works with all GI receivers from 2750 and newer - General Instruments old address zip code 92121 (includes GI-350I - GI-650I and older models)

Reboot - Initialization

Removing power does not help boot up process, and lcd display indicates 1.  Screen may list a page of numbers.   Disconnect lnb line or sat input coax line to dish, from receiver.  Remove power cord for 10 seconds and apply power to unit. If receiver boots up normally, then the coax has a short or the lnb needs to be replaced. If no initialization, then receiver needs to go to factory for reprograming memory..

Mistuned Satellites  

Select an arrow button while on an known analog channel ( 1-24 )  Move the left or right arrow and highlight the dish  display,  Adjust the arrows that correspond to fine tune, then enter function button, this will retune your dish or skew positions. Exit to save those settings.  This will reposition-Satellite.

Low or No Audio

Low or no sound can be fixed by holding the up and down arrows at receiver. ( most receivers are set at 000 or A0 ) Hold down 4dtv Button on remote until red led falshes, then enter three digit 10_ and the last number that corresponds to your receiver setting.  In this case 0 (should enter 000 for default receiver settings) Adjust volume up button - see gray-bar-graph indicating volume level on screen. Set to desired (usually maximum) Reprogram satellite button to previous setting when completed.  ( Example 4dtv button - 000 )          

Incorrect Time

Call (NPS or Netlink) or your programmer to correct problem.

No Hits

No hits with a 4DTV 920 can be caused by a weak lnb or one that has excessive oscillator frequency shift.  (slight sparkle on analog channels?) Recommend replacing with a digital lnb before sending in for repair for no count in options 6, 5 from your programmer. 

Pixels - No Signal When Changing Channels - Lnb Test

Complete picture loss when changing channels is due to a lnb that has severe local oscillator drift. The test for this problem is as follows:  Press options 6 0 5 bringing up diagnostic screen A - Use right arrow and go to C screen - Look at first number on second line: Should be between -1.000 and +1.000 If that number is beyond 1 replace lnb: Digital Replacement Lnb (*Note the Eagle Aspen is a full digital lnb)

Remote Control Problems

• No Remote Function on TV (codes in reference book) or press TV button until flashing, then use channel up until set turns on or off. Then press TV once to set.

• No Remote Function in Satellite mode - See Change 4d-function below

• Limited Range Check batteries - 920 only - remote to receiver distance short range: **Uhf coils need to be tuned inside receiver - Adjust using a non-metallic probe and adjust while other person is changing channels with remote.  (requires spreading the coils slightly) If unsure, have a tech. fix this.

• Change 4dtv function (Press up/down arrows same time at receiver - then arrow up or down to change. Use enter button to store - Hold Remote 4dtv button until flashing - Enter 00_ and receiver number (Rcvr# 002, 001, 003, 004) Control needs to match receiver setting to work.
