    New project Emerson/Funai LF320EM4A

    Hi-
    Took on another project. This LF320EM4A has a black screen and a flashing red light. The board in it is a combination board of power&video which I have already replaced. After attempting to power it up the red light flashes 4 times and then goes back solid red again. I cannot see any image with a flash light on the black screen or any evidence of the LEDs coming up. I have read a lot on this and it has been suggested both the LED strips or the ir sensor are the problem and this is common on this model apparently. Before I go and waste money on the wrong thing again I thought I would ask here. If pictures of anything are needed, let me know

              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.              ...
