Yes on both counts. It's a 922. Mike mentioned the battery as well. Is it one of them things that just rolls over dead on you one day? Is it serviceable once it does die or do you now own a doorstop?
Will the receiver 'learn' not to go to G0 for the guide at night or is now a manual process to point it to G1?
I talked to the guy today and the swap is on. I'll have the 922 hooked up 'for real' by this weekend. Right now I just un-hooked the c-band LNB from the HTS and piped it to the 922.
BTW: the guide has now moved to G1 ch 3
I put up a thread on a 4dtv 920 battery swap out. It is here somewhere. It was more of a mechanical pain since on the 920 the battery sits underneath the VCII metal cage (have not looked at the 922 and probably will not for a few years!)....You need a Torx screwdriver to open the case and get the cage out of the way 1st! Darn...I did it before I discovered this forum or I would have taken pictures!!! Suggestion...do not mess with Lithium batteries unless you are well protected and know what you are doing...a volt/ohm meter is very handy! (I use an old Fluke)
Tools I used:
APC Computer UPS 1000V model but any will do! (Auto voltage regulation up and down ...AVR
Torx T20 wrench (screwdriver)
SAFETY GLASSES!!!
long sleeve thick shirt in case the battery burst
thin rubber gloves...SURGICAL TYPE CHEAPOS
VOM meter
Solder and low WATT ADJUSTABLE solder station (I used 300 degrees)
CLIP ON Heatsinks (optional)
Solder sucker...ONE SIDE OF THE BATTERY HAS 3 LUGS AND IS A LITTLE TRICKEY
Insulating towel to keep the card HELD cage OUT OF THE WAY so i did not have to clip the tie wraps holding the harness that attach to it AND IT COULD NOT SHORT ANYTHING OUT IF IT DROPPED OR CHANGD POSITION (you must be careful not to short anything!)
New lithium3.6 V battery with attached leads (Tadrian TL5155p)***
AND A LOT OF WISHING ...again, all went just fine and I also used the opportunity to clean out the 10 yr accumulation of dust with compressed air!
***There are also 2 unused battery pads on the 920, so the 3.6V AA battery and holder from radio shack should work as well! (I will do THAT mod on my VCII unit...I chose the soldered direct replacement on the 4DTV since it stayed on with power during the amputation!
here is a link to changing out a VCII battery which is quite similar...will give you the idea!
http://www.pacificsites.com/~alanjudd/vc.htm
I did it while the unit was still plugged in to keep the id intact while I had the old battery out, and cleaned up the pads while I was at it....all went well and it is now my spare (they age more when used (from the heat)....keep unused lithium backed up stuff in a cool spot)...The 920 was 10yrs old, which in theory is the lifespan of the battery. When I measured the voltage of the old one, it was still at 3.6 Volts! HOWEVER, with lithium, that could have changed overnight!!
(my VCII board is 13 yrs old with the orig battery...it is next on my swap list as soon as my refirbed one arrives.)
That area on the 920 is low voltage, but you should not attempt the swap unless you know your way around pc boards.... and old lithium batteries have a nasty habit of bursting, especially where that fat object on the lead is! (that is a fuse and is VERY delicate) and have good soldering skills and tools (put it on a UPS first, just in case of a power bump while the old battery was out!)
Hope this helps...also see the thread.
