    (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!

          Panasonic P58V11B 8 and 12 blinks error "fix"
          by Biruslapio
          Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

          Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

          Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
          by Nairolf
          Hello,

          I have a Samsung DM32D display.
          When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

          Here’s what I have tried so far:
          1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
          2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
          3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

          From these tests, I suspect the problem might be on the mainboard. Could anyone...

          Panasonic TC-P55ST50 8 blinks then no blinks
          by Andre Gilbert
          Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

          Optiplex 3050 micro 2 blinks followed by 3 blinks issue
          by Taurus12
          Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same

          I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.

          i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights

          Any recommendation on what I have to do next? Thanks in advance

          Sony A1e 5-blinks help
          by jchon
          Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

          I found the service manual, which was critical to know where to probe.
          https://www.manualslib.com/manual/20...1e-Series.html

          With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

          Unfortunately the 5-blinks...
