No Sound

c6usaOGR Forum Member DIGITAL SUBSCRIBER

Today at a train show I purchased a PS2 engine BL-2 PS2 3volt board 20-2686-1 I was told up front there was no sound. When I got home its true no sound. After factory reset still no sound. I checked the speaker shows 3 ohms so that's good. I pulled the body off all looks good there. BCR installed. It only shows 16.59 on the DOD and 5 hours on the DCH. It runs good and the smoke is good as well. Is there anything I can do short of replacing the board. I also came across a I3A TIU with the remote it has 4.1 software (that's old) soon to have 6.1 but it works I will keep this as a spare.

Thanks Henry

If it has all functions, but no sound, 90% of the time replacing the audio amp will fix it. But, you need to find out why it failed. Motor leads or smoke unit grounded, pinched wires, etc. It’s a $5 part, but about 1/4 the size of your finger nail with thread-sized legs on each side. Find a tech that will replace it for you..

Look very closely at the audio amp on the bottom, it's U5. Many times you can see a bubble of heat damage on them, if the speaker gets shorted to the frame, they draw excessive current.

Thanks guys, By chance can either of you if you have time post pic and part numbers. If it just a solder joint I think I can handle it.

I found the post from 2016 that shows the chip and the link to buy from.
