    Hp 15 5 blinks and 3 fast blinks

    Please has anyone encountered any problem with this hp pavilion series,
    Board IdAX1BMBAF0, It gives this caps lock blinks with no display.
    5 slow blinks and 3 fast blinks. According to hp troubleshoot they state that error code to "The embedded controller has timed out waiting for the BIOS"
    I have reprogrammed the bios but its still the same

      Change Oscillator near ENE. . . . Problem will be solved.

        What is this "ENE" you speak of? I'm having same issue.

          It is probably SIO chip.

            I had the same issue ,resolved two days ago


            You have to check crystal (oscillator) near PCH
            It is a clock generator (frequency generator)for PCH vice versa

            Second check Vccsa coil near SD card slot there should
            Be above 0.94 voltage.

              Not sure what an SIO chip is. Well I tried to perform a BIOS reset before I got your message by holding Windows key and "B" and now the fans spins for half a second and the power button light goes off, so now I am not even getting a flashing caps lock. 2 steps backwards...

                stingerchamp, So even though board does not power on I checked Xtal with silly scope and I do have a 32KHz RTC signal. Not sure which coil by SD card slot you are referring to. I have the board out of the case just FYI

                  Still getting 5.3 blink code. Could the SPI IC be bad itself? I tried to flash the BIOS and nothing changed.

                    It started out with a bad battery (puffy cells)

                      I figured out what "SIO" means. "Super I/O" aka "EC" or "Embedded Controller" IC

                        Can a bad battery kill the SIO?

                          My board was dag35dmbad so in your case it may not be the vccsa coil issue
                          Vccsa coil is connected with CPU core supply

                          Anyhow

                          If bad battery then remove it and check
                          It is good you have 32khz clock available means rtc circuit is fine provided 3volt available at rtc battery

                          If your charging battery is faulty replace it and check

                          Software check:if 3volt available at cell, have you tried CMOS reset by pressing ctrl+v key while holding power button ,read hp page for details

                          Replace ram or use different ram slot and check

                          Do hard reset to remove any residue voltage in motherboard

                          If all fails time to work on motherboard

                            Anything can kill anything, but it's really unlikely. Batteries can't magically fail into producing more voltage than what they're charged to, and there are several layers of isolation between the SIO and the battery itself. If the SIO is dead, it's probably not because of anything that the battery did.

                                          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,
                                          As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...

                                          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...

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...
