I recently picked up a Nintendo Famcicom for pretty cheap off ebay, to power it i have picked up this power adapter from console 5 https://console5.com/store/9v-1300ma-ul-...

I have the TV set to channel 95/96 which is the Japanese channel 1/2.

Hitting the power switch causes a black screen with fuzzy moving blue and green anomalies. If a cartridge is inserted into the console I can hear audio coming from the controller II microphone. No game audio. Ive cleaned the cartridge and connector incredibly thouroughly. There’s clearly some sort of processing going on in the console because i can hear the microphone through the TV when a cartridge is inserted.

I swapped out the 7805 voltage regulator, but no change, i have some spare capacitors to replace as well but i don’t want to start throwing parts at this thing without a cause.

Any help is appreciated

EDIT 2/11/24

Voltage regulator and all capacitors replaced, board, cartridges, and cart slot have been cleaned and then cleaned again for good measure. Same result with no change. Ive ordered a known working cartridge because I only have one and am unsure if it works

Post updated to include board photos after voltage regulator, cap replacement and cleaning. Not sure what the quality of these photos will be over internet compression. However the Board revision is HVC-CPU-07

Excuse my naivety. I purchased an original Japanese Famicom in Super Potato, Tokyo recently for use in the UK.

At the counter I requested them to provide power supplies - I was provided an RF Switch and Japanese AC Adaptor (100V AC 50/60hz with 10V DC 850mA)

Upon returning, I purchased this RF Cable: http://www.ebay.co.uk/itm/RF-Cable-Super...?

So I hooked up the RF Cable (didn't use the switch), and combined a Travel Adaptor + The AC Adaptor I was supplied with the Famicom and immediately after switching on, I noticed white smoke coming from the Famicom and a pop/bang noise after 5 seconds.

After realising I should be using a step-down convertor or a plug with the current AC Voltage I purchased this and tried using it tonight:

http://www.ebay.co.uk/itm/151415102678?_...

Unfortunately, the Famicom now when turned on doesn't seem to emit any noises or sounds, and the temperature remains the same so I can only assume it's broken - perhaps I've blown a fuse?

What's the best thing to do here?

Option 1) The Famicom is dead, I should just give up

Option 2) Is anyone here based in London that could perhaps take a look at it? I'd be happy to pay for your time & parts

Option 3) Is it possible I've blown a fuse or something that I could fix myself in a straightforward way?

I recently bought a famicom off ebay in box with four other games, the original box was tattered but the console was in decent shape. I tried to use the japanese RF adapter with my TV but soon found that it does not work on US televisions. So I bought a US RF adapter and the console still shows no video… Any troubleshooting tips? I don’t have any idea what is at fault here and I’m not familiar with the famicom either…

Thanks!
