tektronix 5103n(D11) Oscilloscope creap
I tried to figure out which section this belonged in, but imaging is the one that seemed closest. I have a tektronix 5103n(D11) and the horizontal line is always slowly creaping down. Even if I have it probing a voltage. I tried probing a 9V battery and it would show 9V at first then very slowly keep moving down. Is there an adjustment I can make or is the scope in need of reapir? Thank you. -

Is having the schematic the only way to know for sure? -

Re: Schematic for LG 55UF6450 TV
When I plug HDMI stuff in the tv doesn't recognize that anything has been plugged in. I do have access to high end equipment. My friend works at an electronic manufacturer as an electronics repair tech. He asked me if I had one so I thought maybe someone here might have the schematic. I've tried many times to buy a new board. They are always either sold out or charge insane amount upwards of 250$. Seems like they are actually worth about 90 to 100$. The only repair service I could find on ebay was for a snowy pictures. Thank you for the replies ...Leave a comment:

Re: Schematic for LG 55UF6450 TV
That says it is repair service for snowy picture. I don't have that issue. My issue is that the inputs don't work. I can stream my phone through tv and it works fine, but if I plug any hdmi inputs in nothing happens.Leave a comment:

Re: Flir One Gen 3 USB C
I already have the unit open. It's supposed to show red light for a few seconds, then go flashing green. then if you hold button it should go off. The red light comes on a never goes off. The power button doesn't make any difference. I have charged it up so the battery should be full. Thank you for reply
