A thank you to all members who posted information that allowed me to fix not one but two lcd TVs! I've never attempted this type of repair, but the information available through this forum allowed me to identify the bad capacitors and how to replace them. My son-in- law gave them to me to sell or fix. I gave one back to him and kept the other. What a deal...........

Re: Thanks - We fixed them!
No, most of the money goes to the resellers and middlemen who import the stuff (i.e. big chain stores). The Chinese manufacturers usually get just enough to keep the business going. But like you, I have no "moral qualms" either way.
Congrats on the fix, jimdandar! The only way to make things last nowadays is to fix them yourself.Comment

Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
TV runs, backlight on, have sound and no image (dark grey/blue/black LCD)
Disconnected right (looking from rear of TV) tcon-buffer board cable, LCD left half displays.
No shorts on right buffer board.
Started masking tcon-buffer board signals... (connection #1 in main board pic) about 20+ pins from top of connector... LCD fully displays with some anomalies.
Gradually reduced # of masking signals... eventually down to 1. Removed that... LCD works perfectly.
No obvious damage on right buffer board 3x COF to the panel like another 43" LG fixed ( link ) with... -
Hello,
I'm currently dealing with a BIOS corruption issue on my HP ProDesk 600 G1 SFF desktop PC.
After the BIOS got corrupted, my PC was showing no display, and I had to take it to a repair shop where the technician removed the BIOS chip from the motherboard and installed a BIOS I provided from a file I downloaded from the official HP website.
While the display issue was fixed and the system is powering up again, there's one major problem: the Ethernet MAC address is now showing as FF:FF:FF:FF:FF:FF, indicating that it's been wiped or corrupted as well.... -
Hello
I have this board working fine designed to 42v fixed output using lm324n chip and i really need to make adjustable output (ideal if Vol and Current with 2 pots but at least only Vol).... i was trying to do it with datasheet and several diagrams but could not
the pins 1 2 and 3 are unconnected so it is using only 3 op amps in the chip.... How do you think I can mod it?
or any hint for an schematic similar.. thks in advance... -
Hello everybody,
I got HP ProBook 455 G7 which originally turned on partially(fans on 100%) and hen off after 8 seconds, with AC diode flashing orange and last flash white. This behaviour stayed for a while, but before I realised that there is power delivery issue and not BIOS problem, laptop started to automatically turn on after 2 seconds when in turned off, kept power cycling. So after I fixed shorted cap and burned ferrite bead, laptop turned on fine and booted to windows.
Now, laptop can be turned off and it stays like that... unless you plug adapter again, which triggers...
