Tswit wrote:Reymon, I can think of two possibilities for your's not working. It is possible that you shorted the back lights when soldering or you may not have a good contact on one of the LCD tabs when you twisted the tabs back in place (those tabs hold the LCD in place and are the electrical connections for the LCD). When you have your radio on, can you see that the backlight are illuminated but none of the numbers or letters on the display? If no, my suggestion is to take the radio apart again an check the new lights with a 9v battery and wire leads. If you have a soldering short, the lights shouldn't light up. If no short, all three backlights should light up. If you can see the back lights when the radio is turned on, I recommend you ensure that all of the LCD tabs are making contact with their respective contacts on the circuit board. I wasn't sure of this when I retwisted the tabs so I put a little solder on each tab making sure I got a good connection. I hope one of these suggestions help you, good luck.

I first changed mine using the RadioShack mini lamp 272-1141 ($1.69 each). These are 12V 25mA (0.025Amp) (Sorry for the bad quality pictures).
I did not like the results. 0.025Amps were too little Amps to light up the screen with the right brightness. So I ordered some T1.75 Miniature Automotive Light Bulbs #2162 on eBay ($1.05 each + $0.99 + Free additional bulb shipment). These are the actual size to fit the white bulb rubbers with the right brightness. They are 14V 0.1Amp (100mA) but they light up just with the correct brightness (I compared my radio screen with my sister's Vibe's). I think that the fact that these are meant for 14V instead of 12V, it will give the light bulbs a longer life.

Thinking if somebody wants their radio fixed and isn't handy with a soldering iron, PM me, send it to me, I'll take care of it.
