My pda is saying waiting and won't connect. I opened up the -box and none of the LED's are lit. I attempted to change the RF chanel also, but neither the red or green LED is on, what should I check.

SOURCE: Coleman 1500 power inverter has no output

I believe that the actual unit may have other problems and that you will need a schematic to aid in your troubleshooting of this issue. Once you have the schematic and a multiment you can check the voltages to see if things ar as they should be and then we can look at what is happening.

SOURCE: will not stay on

FIXED IT!!!

So if you have a blinking red protection LED:

Turned out the pico-fuse for the -23V had 130 ohms resistance. Initial continuity test feature on my meter indicated it was good since anything under 200 ohms is continuity. All of this after many hours of frustration... and not understanding why all secondary voltages on the power transformer were at 50% for the 2-3 seconds of power up before shutting down.

The "leaky" pico-fuse turned into resistor allowed enough power to illuminate -23V LED despite voltage being 1/2.

Replaced with new pico-fuse to get true -23V. All other output voltages followed suit and TV is working perfectly.

Don't trust the green LEDs. Measure all voltages and be sure to verify 1 ohm or less for every pico-fuse.

I don't understand how a faulty -23V rail would cause this problem. Feedback is from the +31V rail which powers standby 12V safety regulator, 9v and 5v switched regulators.

Anyways it works now.

Unable to Tune TV to Sky + RF output


Hi.

The problem is that the modulator output frequency of your sky box is exactly the same as for example chanel 5 on your terestrial aerial.
You need to change this number to a different one thats clear of local terestrial transmissions


1) Select the Services button on your Sky or Sky+ remote control.

2) Type in 401 [select] on your key pad and you will get to the installer menu. You cant gain access to this via the drop down menu as it is designed for the Sky Engineer to use.

3)
Select Option 4 to configure the RF outlets on your Sky Digibox.

4) The option RF Chanel Number change this number from example 35 to 60 .
You may need to do this using other numbers 26 34 55 etc
Every time you alter the number store it then try & tune TV to sky.
Any other sets in the house connected by RF leads will require retuning for sky.
Save new settings and you should find that your RF outlet to TV works fine.

Rf2 outlet from sky hd box


on your sky remote

services

0 1 select

make sure the rf is set to on
Remember the channel rf number,

go to your television the link is to.
go to menu then setup and then manual tune
select the channel you want to view sky on. normally channel 6 on your analogue
then go to Channel type in whatever the rf setting was on your main sky box then press save.

that is your telly sorted out. if you have a magic eye connected at the link end you should see a red led light lit up.
if not remove the magic eye and connect it straight into the back of your sky box RF2
just to make sure that the eye is not at fault.

hope this helps
ill check in a day or two to see if you need more help.

Cheers
