    Hitachi 55VG825 blowing bulbs

    Hi everyone
    Got this 55" projector for free, said bulb needs replaced, so replaced the bulb and it worked for a few minutes then blew the bulb, so i pulled the back cover off and saw this component(in pic, circled) glowing every few seconds, and squaking while it cycled on. Couldn't find the schematics for the lamp ballast anywhere, and haven't pulled the power board out yet.
    Any ideas on why this glowed, or any help on direction without schematic would be great.
    Cheers

          so this should glow if the bulb is burnt?

              TOSHIBA DLP 52HM95 How to reset timer module on bulb
              by repair-it
              I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

              Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

              Hitachi 32HAE2351 Vestel 17MB171 - Rotate Image
              Mainboard: VESTEL 17MB171 Chassis: VES315WNGB - 2D - N52
              The TV was stuck on the logo and I couldn't access the update menu.
              I couldn't find the firmware for the Hitachi 32HAE2351 and updated it with the Toshiba 32WA2063DG - Vestel 17MB171 firmware.
              The image result was good, but the image is inverted.
              The image rotation/mirror function doesn't exist in the Menu Server. I can't correct the image.
              Do you have the firmware for the Hitachi 32HAE2351 - Vestel 17MB171 motherboard or a solution to rotate the image in...

              LUMIMAN Smart Bulb IC ID?
              by ezenia
              Hi,

              I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

              In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...
