Just clip each leg on the old channel display with some sharp nippers then de-solder each leg individually and you may want to get yourself a de-soldering tool from radio shack.

Be sure to clip the old legs as long as possible to give yourself plenty to grab on to.

Then just drop the new one in the old slot and alternate from one corner to the other as not to over heat any one section of the display.

Well, unless you have some way to cross reference the display part number with the TRC-447 there's no way to know if it will work in your radio. Honestly, if you have not done any component replacement like this..it's not the way to start unless you just want to try it for giggles and don't care if you damage the radio. Sorry if that's not the answer you were loking for.

Here's a link to the schematics and other info that may help.

This is the blue one for that radio.

LED 7-SEGMENT .40" 2DGT BLUE CA - LTD-4608B

 

[littleman23]

well so if the pins are the same and its the same size it should work right?

littleman23,
Did you get the ebay LEDs to work? I would like to know how you're coming along.

mackmobile43, would you happen to know which blue display LEDs fit the TRC-448? The Radio Shack display P/N is LO831, "MFRs P/N" SG-N72-01. It's 2-digit, common anode.

Not without researching it.

Thanks, I'll see if I can research it. Somewhere, I have one of those rulers calibrated in tenths of inches.

Best advice is to practice on an old scrapper of a radio,removing the led display (or any other multi pin components) with a solder sucker,then resoldering it/them,till you get it down to a fine art,before you go doing it to a serviceable radio otherwise you may do serious damage to it that may cost you a few bob/dollars to get repaired.

That way you will become very proficient at soldering/desoldering in a short space of time,and risk no damage to good equipment.

p.s. just because led displays have the same physical size/pin spacing they may not be the same pinouts.
