I've enjoyed my S01 since the early 90s, and it was still working well up until a few months ago. It was in a rack in a heated room and suffered no shocks. Powered up, floppy confirmed, channel lights lit, digital display on, data knob responsive, but the edit contol subpanel remained dark & unresponsive. Everything in the box appears good. No capacitor leakage. Has anyone been here before? I could use a/some guidance. Obliged 🙏

by sumilumiHi fellow troubleshooters. This is my first post on badcaps. I've recently setup an electronics workbench. i'm also building a studio with old equipment bought faulty at low cost.
I've been into electronics since the mid 80's and particularly in the last few years though only getting hands on with repairs now. My knowledge gaps are significant so I'll be posting here to seek guidance advice and general practical applied learning.
On my bench today is an old ca. 1993-95 Akai hardware sampler. This runs on both a linear and Smps supply. Both are getting on in age and ripple... -

The TV does not turn on, the standby indicator is on. All voltages are present.
Emms is dead. Not readable, not detected.

by howardc64All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

by ctroxtellI've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working. The button...

Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video
Model & Board Pics
Conflicting Spec
Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12
