    Coby LEDTV4028 and LEDTV5028

    Hello. I have each of these Coby TV's sitting here, brand new, dead. 40" doesn't power up, and the 50" will work periodically. No parts seem to be available. What I was wondering is (1) has anyone else worked on this with any experience as to what their typical problems are, and (2) are these parts used in other brand TV's? Trying to determine the effort I should put into these...

    Thanks

    Joe

                  Samsung UN65JU67ODFXZA Version TD01 Schematic and Parts List
                  by Mark D
                  The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts...

                  What parts can be salvaged from a plasma with a damaged display panel?
                  by SurrealMustard
                  I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad...

                  Asus Rog Strix B360-I Gaming - Parts Identification
                  by DynaxSC
                  Hi,

                  I have an Asus Rog Strix B360-I Gaming with missing parts. I know there is a resistor missing for sure, but nearby it seems there might have been also a transistor or mosfet. Below the picture of the area on the board with the missing parts. The interesting area is inside the rectangle.




                  I'd appeciate if somebody could make a detailled picture of this area from a working board and post it here. Getting the parts values would also be helpful. The revision of the board is 1.02 .

                  Thanks in advance...

                  3090 FE Part Confirm/Identification
                  by H H
                  Hello,

                  I'm hoping someone could help me confirm if I have identified the following parts correctly.

                  Apparently the DP cable became stuck inside the graphics card and was yanked out. This caused some sort of short which burned the DP contacts and blew some resistors and ferrite beads.

                  The parts needing replacement are on the back of the board behind the HDMI input.

                  I have identified the parts as the following:

                  C6037: MLCC 0.1uf/16v(0402)x7R W05

                  R6016: RES 499 OHM 1/16W (0402) 1%

                  LB10911: Ferrite Bead (0402)...
