Hi and welcome to FixYa,

If the 4 diodes you referred to forms the bridge after the transformer, then the below screenshot of that particular part of the circuitry should help/guide you.

Based on your post, what you further need is actual parts placement that would only be available with an actual identical unit at hand and boards removed. I doubt if even the service manual manual could provide parts placement.

Good luck and Thank you for using FixYa. Happy Holidays.

Let me know exact model of unit. If you post picture of Circuit board where you replaced these diodes would be helpful.
I will provide you proper schematics to resolve the issue.

Why does the fuse on my old lbt-d270 sony -disc changer keep blowing a fuse everytime I replace it?


Short circuited component/s at it internal circuit board. Contact any service technician. Never switch it on; without the fault have been rectified. It might make troubleshooting more complicated, and might cause more components damage.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Where is fuse located


Remove the back panel of the unit. If the fuse replacement blows again as soon as you turn the unit back on, you might have to troubleshoot the power supply. Good luck Mike!

No POWER UP NO DISPLAY AFTER A STORM


you must have had a power spike during the storm, I tried to locate this model specs but couldn't,, if you can get into the back where the plug wire leads into the unit,, if there is no visible fuse, you want to look at the circuit board where the plug wire attaches to it, near that point there will be a diode thats blown, it will be easy to locate it should have pretty much exploded. if your knowledgeable with soldering you can purchase another directional diode and replace the burned one, if not, have a shop do it,,

I have a rca rs2640 stereo system. The display, cd player, tape player, radio, and headphone jack all work. But when a cd, tape, or radio is playing, the speakers do not make any sounds. I know it is...


It sounds like maybe you have speaker wires touching somewhere. If they are touching it will blow fuses, especially if you turn the volume up to try to hear anything. DO NOT put bigger fuses in to replace the old ones, you will actually do more damage to your system because a higher volt fuse will allow a higher voltage to "spike" in your stereo and might just start frying internal parts.

Had a problem with a customer's stereo system, i replaced the transformer and put in two new fuses and all worked good again. Another time it was a damaged capacitor allowing full charge to go through causing the fuse to blow immediately so i just replaced the capacitor and the fuse and all was good.

RCA 5-CD Shelf System, RS2654 Fuses


Never ever replace a fuse with a bigger one, you are lucky the unit did not blow up and statrt a fire. When a fuse blows there is usually a reason.There is a short in the main power supply or the output stage. You will need to test for shorts on the main transformer, B+ rectifiers and the main filter capacitors. If that does not show any shorts, you will need to test the audio output circuits for shorts on the audio output IC's. Good Luck

Fuse


If the fuse blew again then there is more than likely a problem with one or more of the boards components. First start by unscrewing the power supply and looking on the underside, you may see some burn marks. If you do then it is likely that the component above the burn marks has blown and needs to be replaced. If you do not see any burn marks then the best place to start is with the diodes on the board. If its still not working, e.g. the fuse blew again then it may be that the problem lies elsewhere on the power supply... Good luck.
