    Sharp LC-60LE640U 2 slow 2 fast blink code repair

    I have picked this TV up a couple of days ago for $25(!).
    It had this error code, with no image or backlight.
    Found a repair kit online, which showed a coupe of parts and board designations as well(sorry I can't find it again).
    Checked those parts, except the IC and found a shorted NUR460 diode, D7805.
    By replacing it, with a MUR460(left over from another similar repair) fixed the TV.

      That is one of PFC diode, so you did have the Boosted Voltage, right?
      Actually the MUR460 Diode fails a lot too.

          The boosted you mean, the 170V? That one it was there.
          This diode it was marked as NUR460.

              Nope, he meant the boosted >360V voltage

                  I have the same tv. 2 long blinks 2 shorts. I have read all I can find, and also found manual too. I'm just going to post some pictures and ask some dumb questions so I can kinda get an idea. Soon as I figure out how to post pictures

                      I also have a shorted D7805. I ordered a 20 pack of MUR460 to replace it. I hope it is the only issue. I checked a few other parts, but might have missed some. I also have 2 long and 2 short blinks.

                          Could you please tell me if you fixed the TV or not

                              Sharp LC-90LE745U 3 slow and 1 fast Blink
                              by c00lman
                              hi, new member her and apologize if this has been discussed.. tried to search and most of the result are for LC-xxLe6xx series and not sure if it's applicable to the 745U.

                              the TV stopped turning on and after the V logo stayed solid for a minute or 2, it gives the 3 slow and 1 fast blinks which from what I researched are internal communication error.

                              did some voltage measurement on the power supply out.
                              Pin 1 and 2 = 0V --> PNL 12V
                              Pin 3 and 4 = 0 V --> GND
                              Pin 5 to 8 = 13V --> UR 13V
                              Pin 9 to 12 = 0 V --> GND
                              PIN 13...

                              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...

                              Bestec ATX0300F5WA - fast,or slow blow, fuse?
                              by socketa
                              I bought a dead motherboard, and connected it to this PSU,
                              Was checking the standby voltages on the motherboard, and, whilst doing so, the PSU made a loud bang with a flash of light.
                              So now i truly got a bang for my bucks, and something else to try and fix.
                              The fuse was blowen, and the top was blowen off of a TNY276PN chip
                              The glass fuse didn't have any marking to say if it was fast or slow blow
                              So i checked the marking on the PCB thinking that that would tell me,
                              but it 's got a T/F8A printed on the board
                              So should i get a fast blow fuse, or should...

                              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...

                              Hello all,

                              I'm trying to repair this A2251 macbook pro. Board is 820-01949. The original issue was liquid damage which all cleaned up well and the board was not heavily damaged. Unfortunately after liquid damage cleaning the computer is running extremely slow and the fan is running at full speed. Even the cursor is lagging. Because of this I can't use the built in hardware diagnostic to give me a clue as to what is happening. Does anyone know if Apple Service Diagnostic software is available for this model? Any other clues which could help me out? Seems to me there is an issue with...
