I thought I spot BeO plates soldered to the copper heatsink plate where copper tracks were deposited on the BeO plates?-
Hi,
I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.
I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
(This board does not respond, only the LEDs light up in a circle.
The liquid damage is catastrophic and restoration is impractical).
(I bought this board to get the WiFi module and camera).
The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?
Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently... -
Hi everyone
I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines
I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector... -
So I got the bright idea to remove the LED light module from the fixture and put it on top of another enclosure and keep using the zapper
The removal of light module was a successful and now I just have to cut a hole in the enclosure and put a power cord that has an on and off switch on it
You are lucky to get about two years of service out of one before the LED module starts flicking and just stops working because it is mounted on an aluminum plate and these are hard to solder on it and it is not worth messing around with them and especially this one because it has line... -
I have several chopper units that need to be repaired but just repaired one of them to see if it could be done successfully which they can be repaired
The company that makes the IGBT module have discontinued this part as 5/30/2020 which our company has bought 12 IGBT modules which will allow me to repair 6 chopper units ( one note there is no direct replacement availability )
I am buying these modules directly from the manufacturer
But there is a 8 week lead time
Now you can find on EBay for half the price but I have a feeling that might be fake...06-07-2020, 11:08 AM
