    (SOLVED, thanks budm!) Emerson LC401EM2F - Standby Light Blinks 15 times, no picture

    Hello all. Long story short (no pun intended) someone gave me this TV and it kept blowing fuses. This started after a lightning storm. Using this link for reference, I learned the "light bulb" trick and also learned that a bad diode may be the culprit.

    So I ordered a replacement, threw it in there, and the light bulb began blinking rapidly for 5 seconds, dimmed for 2, then repeated.

    Following this service bulletin    , I removed the newly replaced diode and the light bulb stayed dark. I threw a fuse in and it didn't blow but I didn't see a picture. Put the diode back in and voila! Another rescued TV!

    Congrats to budm! Another saved TV!

          Lithonia Lighting versus Light of America Compact Fluorescent product quality
          by sam_sam_sam
          I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

          I also have back when Light of America had these light bulbs available for yard lights

          The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

          While the Lithonia lighting fixture has all most certain bulb failure

          So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

          I have only had this light fixture for not more than a year if it...

          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
          by serious_electron
          Hello Everyone!

          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.          ...
