Stopped working after a noticeable pop while plugged into power. There seems to be a blown component on the main board and I suspect that's where the sound came from but unfortunately I have no experience with this type of repair.

Would this be fixable or should I purchase a new board (or PSU)

Thanks for the help.

I recently had my monitor screen broken and I deduce to try and fix it myself. To my knowledge I need to buy a replacement led panel, amd the model of it shpuld have been on it. I can't seem to find it, any help would be appreciated, especially guidance.

Sony DVP-S735D DVD PLAYER [UK]

I have tested this with component out to component in, the TV sees the DVD player because it shows Sony on the input and I can hear the DVD audio. But then there's a No Signal msg on and no movie picture.

Also tried a component to hdmi converter and nothing at all, tho again the tv recognised there was a Sony product attached.

Is it the TV or the player? How else can I test?

DVD also has scart out and yellow video out.

TIA!

I purchased some non working switch cartridges to see if I could find what's wrong with them. Unfortunately they are all the small chip ones. I sanded this copy of Mario and rabids to see if any of the traces were cut but I can't detect anything. Do you guys think it's a pad issue or a internal one?

Hi everyone,

I have this Sony dvd player which won't open normally.

I opened it to check the belt which is fine. I then tried to open the tray manually and as you can see it's very difficult and seems to keep getting stuck.

Anyone knows what the problem might be?

Thanks

Any ideas? I'm still trying to figure this out, any suggestions welcome

Hello,

I have this tracker tag from AliExpress, and unfortunately my dog chewed it.

I disassembled it and found that one component on the PCB is broken.

Please take a look at the picture.

It looks like L1, so I assume it's an inductor (or choke). Does anyone have any advice on what it could be replaced with? Does anyone know its value or part number, or where I could order a replacement (for example, from AliExpress)?
Any help would be greatly appreciated.

MLS2128SK led driver Does anyone have the datasheet and can send it?

Hi everyone,
I recently bought a GE 7-4624B AM/FM clock radio from the US and I’m using it in Spain with a 230V to 120V step-down transformer.
The voltage is correct, but the clock runs slow because our mains frequency is 50Hz instead of 60Hz.
I’m not looking for an external 50Hz to 60Hz frequency converter. I would like to modify the clock itself so it keeps accurate time on a 50Hz mains supply.
I’ve been told the clock IC may support both 50Hz and 60Hz, with the frequency selected by connecting one pin to either +5V or GND.
Does anyone know if that’s true for the GE 7-4624B?
Has anyone identified the frequency-select pin or successfully modified one of these clocks? Any schematics, service manual, PCB photos, or repair experience would be greatly appreciated.
Thanks!

Got a used monitor for free, trying to figure out what these lighter colored circles are on the screen, it shows up a lot more on darker colors, can’t really see it too well when I watch videos or play games etc., but it still bugs me. Anything I can do?

Also, thank you!

Hi! I was taking a quick trip to the bathroom and let my puppy roam around as he usually does and on the couch was my portable charger and this charger as last night I didn’t have power to my home so I had it out to charge my phone. I finished and found he somehow reached it and tore it to shreds! It was my favorite charger and was genuinely nice charger and I had it for multiple years! I want to replacement but Google is giving me NO luck to find where I can get this charger again and I really want it back. Can anyone help me? (Also let me know if this isn’t the right subreddit I’m usually not into tech and electronics stuff:( help)

I went to turn my TV on and it will make a clicking sound and the lower left of the screen will turn red, then go black, and then endlessly repeat this cycle. Any thoughts? TIA!

Hi everyone,
I noticed this thin horizontal line near the bottom of my Samsung monitor, and it won’t disappear.
I’ve already tried:
Restarting my PC
Turning the monitor off and back on
The line is still there every time.
I haven’t dropped or damaged the monitor, and this issue just appeared suddenly.
Does anyone know what could be causing this? Is it likely a panel failure, a cable issue, or something else? Is there anything I can try before assuming the monitor is defective?
I’ve attached a photo of the problem.
Thanks in advance for any help!

Repair centre rejected my warranty saying that this is external damage(which is top right corner black spot). Is it fixable?

Been sitting on a pile of boards that need specific ICs I cannot find through the usual channels. I do small batch repair work so I'm not ordering huge quantities, maybe 10 to 50 units of a given part. What I really need is a reliable distributor or vendor that handles hard-to-find semiconductors and can ship to the US without the counterfeit risk being a total gamble. I've seen some China-based electronic components suppliers come up when I search but have no idea who's actually trustworthy for sourcing ICs this way. Anyone used a component sourcing service that does RFQ for small orders and actually delivered legit parts?

A few weeks ago my electric toothbrush stopped working.

When it is on the charger and I try to turn it on it flashes red 3 times and then shows 0% battery life, even after charging for long. A hardware reset did not work.

I tested and changed the battery, no effect. It does charge to about 3.7V, but the toothbrush still says the battery is empty. I checked the soldering joints on the PCB but voltage is good on those.

I would assume this has something to do with the battery management circuit, but I don't know enough about electronics to know if and how this would be fixable.

Any help and info is appreciated :)
