    PEC? Semiconductor manufacturer identification

    I've found this logo in many chinese diodes but never found a single datasheet or a website from PEC. Well, that's how I read that logo. Perhaps that's my fault. I've drawn the logo myself, with the hope that Google images would match something, but no results... any idea?

              Help identifying PCB FS-750-2025 with TEA2025 – unbranded multimedia speakers
              by Alucio1970
              Hi everyone,
              I'm trying to identify the origin of a circuit board inside a pair of unbranded stereo active speakers. No logo, no model number—just generic "MULTIMEDIA SPEAKER SYSTEM" printed on the front.

              Main details:
              • PCB marked FS-750-2025 with a logo that looks like a stylized sail inside concentric circles
              • Audio chip: UTC TEA2025, stereo configuration
              • Potentiometers: B50K (Volume, Tone, Power)
              • Capacitors: 470µF 25V and 1000µF 25V
              • Transformer: 230V~ → 19V AC 350mA, thermal fuse rated 115°C
              • Speaker: 5W driver with magnet labeled “JY ม5w” (Thai

              MacBook Air A2179 stuck logo , pls help me !
              by conghuyms
              Hey everyone,

              I’ve got a MacBook Air A2179 that got some water damage through the keyboard. Now it powers on, shows the Apple logo, but just stays stuck there — no startup chime, no keyboard backlight, and no progress bar under the Apple logo.

              When I try to boot into Internet Recovery (Option + Command + R), the mouse cursor is extremely slow and laggy — like when I lift my finger off the trackpad, the cursor keeps drifting slowly for a second or two.

              I opened it up and found some corrosion around the LED driver IC area on the logic board. I cleaned...

              Hi folks!

              I am trying to repair a Daikin air conditioning unit's filter board where I came across this ceramic coated IC:


              It is likely an AC-DC power supply converter, however there is no output voltage on it and I do not know if there are any enable lines for that.
              The primary side is clearly understandable: it has AC input and has a DC rail where a 100V 470 uF is present, however on the secondary side there are 4 pins and their function is unknown.

              I have not found any datasheets or schematics containing it on the web, so any guidance would...

              Component Identification
              by grimacelord
              Hello. I am working on a circuit board that is part of a motorized HDTV lift. The circuit board belongs to the controller component that tells the motor to either raise or lower the HDTV height.

              The controller started sparking when the 29V power supply was attached and the green light on the power supply would go out as soon as it was plugged into the controller board. This indicated a shorted component and I was able to identify which component it is that is causing the short. When I remove this component, the short is cleared.

              The problem is finding a replacement component....
