Ok, i bought what is supposed to be a new power board, because when I 1st got this tv, it had no power that i noticed, whatsoever. So, got the powerboard, and now I notice the little boomerang/chevron a the bottom of screen in bezel, lights up 1 blink as soon as I plug in a powersource. Still nothing else. I never noticed if it lit up previously but now does. Anyway, the screen or tv still doesnt work. Is the mainboard going to fix it? How can i force power on? Ive tried the channel up volume down power button simultaneously, at different times, different variants all to no avail. Ive read somebody refer to a jumper at the 5v to the PSON. I dont really know what that is, but BrainLikeSponge.

MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
I have repaired a Sign WiFi Smart Plug with model number: SNSM-WASINGLE sold by Spares Nordic AB in Sweden.
The fault condition was that the device gave no signs of life: pressing the push button did not cycle the internal relay and the blue LED did not come on and it was not seen on the WiFi network.
The fault was very simple, capacitor C3 on the PCB with writing "KSJ" and "LOWESR" had literally blown its top off, after replacing it the device works fine again!

Hi folks!
I have a LC-80LE661U that had some interesting issues.
Initially, it would come on and show the sharp logo and would show normal static before shutting off.
I started troubleshooting by disconnecting the led lighting strips and turning it on. It would do the same thing - come on, show the sharp logo and shut off. After reading, it was suggested to replace the main board. That was replaced and the same symptoms resulted. After this and some reading, the parts cannon got loaded up. I replaced the power board, same issue. Replaced the Tcon board and now it...
