Electrolux EUO9GREEN Vacuum Cleaner doesn't start
I have a vacuum cleaner that won't start. I have desoldered 2 capacitors with low value. But i don't know if they can cause that kind of problem. Someone here with any thoughts and inputs?
I marked the capacitors on the pcb picture with red and blue dots. The big one marked with 334 K measures 216 nF and the other one marked 224 K measures 109 nF.4 Photos

Samsung HG46EB690QB doesn’t start up
I have a Samsung tv that doesn't start up all the way. When I turn it on it says “starting” in the right upper corner. Then following message appears, “ Please check your network. Please contact front desk.” Then after a little while the tv shut down. Then i have to start it again and it repeats.
Someone who has a clue?Last edited by Henke; 07-05-2023, 11:52 PM.

Samsung HG55EB690QB No backlight until disconnecting mb
Tv has stb–light (flashes x6) but no backlight. When disconnecting the cable between psb and mb backlight comes on, but no picture.
I had a smaller tv with the exact same problem and mb. I got hold of one mb on eBay and that fixed the problem. But now i can't find one.
Someone with any thoughts?

Re: SAMSUNG UE55MU6405 - no standby
This is interesting. I had a samsung with similar problem. But i had standby light, dark screen until i disconnected the cable between ps and mb, then the backlight lit up. I fixed a new mb from eBay (BN41-01990A) it's an hotel-tv. that fixed the problem. But do you guys mean that i could fixed it with new firmware?

Re: Samsung TV - no backlight, except when mainboard disconnected
Thank you for the inputs.
I found something strange. A component marked with "AA5"
Can't find what that is..I also found a couple of shorted resistors around that component. I marked 2 of them in the picture (there are a few more).
How do you now what values those should have? ...

Samsung TV HG46EB690QB No picture, only backlight when disconnected mainboard
I came across a Samsung tv that does not seem to start up. When i plug it in nothing happens except that the red led turns on. But when i disconnect the mainboard, the backlight turns on and immediately turns back off when i connect the mb again.
I have tried to disconnect one, none and both cable(s) from the Tcon to the screen but it makes no differens. The PSU seems to work, but when the mb is connected one of the 5V cycles high and low.
Anyone with inputs?...

Re: Samsung TV - no backlight, except when mainboard disconnected
Hi, Did you solve the problem? I think i might have about the same problem now with my tv. The backlight only comes on if i have the mainboard disconnected.
as soon as i connect it, no matter if i have one, none, or both sides on the Tcon
connected it turns off immediately.
