    Sharp LC-37HV4U power LED blinks red

    Got a bad Sharp LC-37HV4U from Freecycle. Lots of fuses and they all exhibited continuity. The capacitors are flat-topped and are Nichicons.

    I got my hands on the service manual, which also services the LC-37HV6U. I got it from ElektroTanya. I tried following that branched decision tree, but I'm not exactly sure about which path to take.

    I hit the Main Power button (which is bigger than the other Power button) and got a steady green LED. I then hit the other Power button and that same LED blinked red. I looked carefully at the blinking behavior and monitored the LED for a pause in the blinking. I didn't find a perceptible pause after that red LED blinked 20 times or so. Using the manual's terminology, I would guess my TV blinked once per cycle.

    I didn't see any change in behavior with respect to the screen.

    I'm going to peruse that service manual some more, but I'd love another pair of eyes to see what items I should examine (or replace).

    Pictures enclosed. Manual's too big to host here, but I found it at:



    Thanks for reading!

      I have the same problem. What did you discover was the cause?

          I haven't discovered anything new ... yet. I haven't yet made time to look at the TV more closely. I've been working on Viewsonic these days.

              Sharp LC-80LE844U Blinks 2 slow, 5 fast
              by joblo37pam
              It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.

              The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help...

              by klassic
              Hi community,

              I will describe my problem with a TV in those short following terms to be the most precise :

              What i have :
              Sharp Aquos LC-60LE635E
              power board DPS-162KP-1
              main logic board QPWBXF733WJN2

              symptoms :
              white led light logo at startup,
              after 2 minutes, blinking 3 times a row, repeating
              no backlight (and apparently no picture, checked panel with flashlight)
              no startup sound

              powerboard investigations :

              1-2 PNL : 0v
              3-4 GND
              5-6-7-8 UR : 13.15v

              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...

              by JayPoorJay
              Good morning... I'm new here and have a LOT to learn.

              I'm a rescue-er. I live in NYC and I don't even want to get started on the amout of stuff that makes it onto the curb, to be crushed and in a land fill, simply because our repair shops have been sold out and because - well, it's a disposable society... Anywho

              I have 1 motorcycle, 3 Jaguars and a Porsche that were all headed to the crusher due to a couple handfuls of needed parts and a Lil Love,,, I'm hooked on the rescue. A member of several forums and a huge fan of DIY environments such as this one. Hats off to you...

              Sharp LC60E79u 2 blinks power/3 Blinks OPC
              by Anzio
              I have a Sharp LC-60E79U with the blinking light error (Power and OPC blink 2 times together then OPC blinks 1 time. I read the previous thread on Sharp lc60e79u (https://www.badcaps.net/forum/showth...t=66913&page=3) with this same issue, but no resolution was posted.

              The service manual indicates this as a β€œDET_5V (33pin) error (L). 5V is not applied.”

              I cannot enter service mode by pressing input and channel down and plugging the unit in to power outlet. However, I can override and enter the diagnostic mode if press channel down and volume up and...
