The unit won't turn on

I had the same problem on my Westinghouse 32 inch TV. The internal main power supply went bad and had to be replaced. I had a TV repair shop do it. It was about 8 years ago. Haven't had a problem since. I think it cost about $70 for parts and labor. Nowadays TVs are pretty much a throw away item if they go bad. TV repair shops are getting hard to find plus the cost of TVs has come down so much sometimes you can get a new set for what the repair would cost!

Here's the manual.

certain cameras can only power up using a more powerful battery such as lithium batteries... if you are using regular alkaline batteries then it will not power up

Remove batteries from room stat,turn off the electrical supply to reciever unit.
Turn back on the electric to reciever unit,the red light should be on,press the top "manual" button,the green light should come on and boiler should fire (assuming the programmer is in an "on" period)
Press the bottom button,and keep it pressed,then press the top button until the green light flashes,stand about 6 feet away,and refit the batteries to the stat while observing the reciever unit,either the red or green light (cant remember which) should flash to show the 2 units are syncronised.

Another basic test if all seems ok,when turning the stat up or down,when the green light on the reciever unit comes on or goes off,its usually accompanied by an audible "click" ive found,that if this is not happening, the reciever unit does not switch either on or off,may be intermittant.
Replacement is the only cure.

If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

Try this first before condeming the unit.

1. Turn off the power supply to the Digistat SCR (receiver unit)
and leave for 5 seconds.
2. Turn on power to SCR unit and check red light is on.
3. Press override button No.2 and check the green light comes
on and boiler fires.
4. Press & hold down button No.1 (Keep depressed), then
press No.2 and keep depressed. {The Red LED light will flash
a couple of times and then it will go out}
5. Now release both the buttons – {the two LED lights should
come back on}
6. Get the Digistat+2RF/+3RF unit and stand two metres away
from the SCR unit with the Digistat+2RF/+3RF unit in your hand.
7. Remove the battery cover and fit the batteries.
8. The Red LED light on the SCR will now flash for approx. 7
seconds.
9. This confirms that the radio signal is being sent and
received.
10. The Digistat+2RF/+3RF and the SCR are now successfully
linked by a dedicated RF address.
