Have a nearly 30-year old Akai stereo receiver AA-R30. Power light just stopped turning on. Opened up case and found main fuse between AC power cord and power transformer blown. When I replace the fuse, it blows instantly. Have repair manual. Does this indicate the power transformer needs to be replaced? If so, how can I possibly find a replacement?

If you pulled the cover and only see one fuse, and if it is not blown, then you need to search deeper for the problem. All replaceable fuses on the main board are viewable.

Remove the top cover and follow the mains cable into the unit. Any fuses should turn up near that. Make certain the power cord is out!

I don't know about the newer receivers but this sounds like an arching OFF/ON power switch that was a problem on Pioneer receivers years ago. I would bypass the switch and see what happens.

1. Unplug unit from wall.
2. Jumper two wires going to off/on switch using alligator clip with insulated boots on clips.
3. Plug amplifier into disconnected circuit breaker/fuse protected AC strip.
4. Plug AC strip into wall outlet, turn AC strip switch ON and see if problem disappears.

diagrams are not to be found for most modern sets as they only sell boards---

google the model with "parts" to locate the board which in most cases will have a photo of it---then you know what to look for

First is the Akai name is owned by Samsung--and here is a general answer:

Red light is shutdown or means only standby light is on.

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.

the power transformer may have blown the primary winding causing no power for the secondary windings witch means that the main power board has no power

in that receiver ther is a fuse that controls the display, I have the same unit, there are 4 fuses by the power supply, it would be one of those, I cant remeber which one but if the fuse is blown it will turn of the entire display. Check that out and if thats not the problem, then there is a short in the unit.

Hi,
Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
Thanks.

Akai LCT 3285TA (notice the "FIVE") uses the MLT169A Power supply. This is available from shopjimmy.com for about $100.

Our VSX-515-S quit suddenly while playing when it was turned up quite loud. The power would not come back on. I disconnected it, and opened it up. No fuses were blown, but there was no voltage in the power supply. When I pressed the on button, I could hear a very faint click, but no power. I even took some parts out and replaced them.

I went on line and bought a service manual download for $7.95.

Within 5 minutes, I found where the service manual said if there was a DC overload, the power would cut off. To reset, press the ENTER + ADVANCED SURROUND key simultaneously and hold for 3 seconds.

I did this and the power came back on. It even remembered the last FM station it was tuned to. Problem s.olved
