Help changing bulbs in a Toshiba SA-725

[@udi0$lave]

I recently bought a Toshiba SA-725 for $20 and I'm working on cleaning it up. The face was covered in spray paint from an overspray, pots needed a good cleaning, bulbs were burnt, etc.

Turns out the bulbs all work, but are intermittent. They are all permanently attached to a PCB (see photos) and I'm wondering how I can install LEDs without soldering if possible. The service manual says they are 14v/200ma. Can I use a lower voltage LED? Any suggestions on how to attach them? Thanks!

Can't help with the math but LED voltage ratings depend on their color. Knowing that figure and the supply voltage will dictate what value resistor must be attached (soldered) onto each LED.

The supply voltage could or even likely be AC in which case a bridge rectifier and a couple of capacitors need to be installed (as in soldered) so the LED's see DC voltage not AC.

I made that conversion thanks to one of the members here who provided me with a circuit diagram. It worked, but in hindsight, incandescent bulbs looked better. I used 3mm LED's and didn't find them bright enough. Might have been better had I used larger 5mm LED's - if they fit the space.

If you're not amiable to soldering, don't bother with LED's. The AK member dgwojo sells replacement lamp bulbs.
