We have the audio output near the bottom right with an Anpec APA2069 stereo 2.6W audio power amplifier (with 32 steps of volume adjustment). The SPW-101 transformer seems to have 12.6V and 6.3V taps and to generate the 5V output they use 2x SB1060 schottky rectifiers. There is a beefy 450V 105C capacitor and a few different brands for the other capacitors (Lelon, Jamicon, Su’scon).
We have a few EEPROMs around, 3x ST 24C02 2Kbit, a ST 24C16 16Kbit some of which I believe would be for the display inputs so video cards could identify the monitor and a MX 25L2025 2Mbit serial flash.įor the power board we have 2 main outputs, the LCD backlight and the 5V for the logic board/5V for the USB port (not populated). The first regulator on the board is a 50117-K 3.3V LDO and second one a AS1117L-12 1.2V LDO, both of which decent heatsink pads which includes the bottom of the board. There are un-populated connectors on the board, 2 on the top right and 2 on the bottom right, one spot for USB (with a separate power rail for it) and an ethernet connector. The logic board is a single chip solution, the RTD2482 which supports VGA (RGB), Component (YPbPr), HDMI, DVI and DisplayPort 2A+2H with an audio DAC, infrared controller and supports resolutions up to 1920×1200 resolution. Powering it up by the power button, I can see the power LED turn on for a fraction of a second, does this 2-3 times before it no longer lights the LED. There was a metal cage holding the power and logic boards but it was just stuck on with some shielded tape, no screws whatsoever which was odd. (forgot to take some pictures of it before I took it apart, so here’s a stock image)Īfter a couple of tough clips and removal of the stand, we’re in. This one stopped working one day, I’ve had it for 8 years so decided to take it apart to see what was wrong. Today we’ll be looking at the BenQ 21.5″ E2200HD LCD Monitor which features a 1080p display, HDMI / DVI / VGA inputs, speakers and a headphone jack.
