Removing led diode from board
I'm trying to replace dead led's from my expensive aquarium lights but I am having a hard time removing the led diodes. I've tried using a hot air station at 500 celcius (932 Fahrenheit) but the led won't budge. I tried blasting hot air from both the bottom and top but it won't budge. I don't have a heating plate so is there a better way? As you can see the bottom of the board is all metal....

Re: Aquarium led lights ,Transistor Identification
Hmm I had another person tell me that it could be a single line eeprom chip. I tried searching and could not find anywhere that sells a single line eeprom programmer that can program a small sot 23 chip. I've seen eeprom programmers before but never one that can program a small chip like this....

Re: Aquarium led lights ,Transistor Identification
Yes D21 and D22 look the same on the working board. Here is a video of one being taken apart. The Led board i'm trying to fix is the pro version led board which has more leds on it then my old non pro ones so maybe that could be why the markings are different as whatever that chip does has to power more leds but who knows.

Re: Aquarium led lights ,Transistor Identification
[QUOTE=redwire;1178625]What make/model aquarium lights are these? Ecotech Marine Radion XR32 I did not find.
It's the ecotech radion xr30 g4. One thing I forgot to mention that may help identify part, is on my functioning led board that chip is labelled B2Y7.Re: Aquarium led lights ,Transistor Identification

Re: Aquarium led lights ,Transistor Identification
I removed the chip and now where it was shorted now doesn't beep on my meter, just shows ol. The problem now is trying to determine what type of chip this is to find a replacement. I still have my old led boards that still work fine, the one in the pics is of the newer led board that I bought off someone and trying to fix as they are better. So not sure if there is any tests I can do with my old functioning led boards to try and determine the type of chip it is....Last edited by ntec; 11-08-2022, 11:35 AM.

Re: Aquarium led lights ,Transistor Identification
[QUOTE=R_J;1178310]What makes you think U1 is defective?
When I looked at it close up it appears to have a burn mark on it and there is a short to ground on the leg. When I checked with my other working board there is no short.Re: Aquarium led lights ,Transistor Identification

Aquarium led lights ,Transistor Identification
Hi, I'm repairing my expensive aquarium led lights and need to replace a broken sot23 transistor. I need help in identifying the correct part to order for replacement. I have attached the pic showing markings of B28W and the transistor sits beside a 0 ohm resistor and a capacitor....

Logitech G935 headset no audio on one side
I have a logitech g935 headset and the weird issue is that one side does not work on wireless but when plugged in with the 3.5mm cable it works fine so I don't think it's the wiring?. I have already updated the firmware and checked all the windows audio settings to make sure the balance was equal etc so I don't think it's a software issue. Should I assume it's a logic board issue? I did take it apart but not sure where to troubleshoot on the logic board. I do have a fluke meter and familiar with soldering if needed.Last edited by ntec; 12-14-2021, 12:45 PM.

Ribbon flex connector replacement
I am trying to fix a tablet that someone botched the ffc/fpc connector on as circled in the picture. When buying a replacement connector I see the connectors are categorized by number of pins and pitch but how do I determine what mine is to find an exact replacement. Not sure if it means anything, but beside the connector it has written a number 1 on one side and 51 on the other side which is also written on the ribbon flex...
