    DV5-1020ev lightning icon flash 3 times

    Hello all
    I have a dv5-1020ev (mb hannstar j mv-4 94v-0 0834) which when I press the power button the lightning bolt flashes 3 times.
    I change the dc adaptor and if I remove the battery it doesnt flash at all.
    I have 19V in the mb in the end of the dc jack.
    In coils near memory and cpu I have 5V and 3V.
    in power ic (isl6237)I have 19V in pin 6 , 5V in VCC pin3, 5V in out1 pin 10,
    I couldnt find schematics for this motherboard although I have 4 schematics for dv5 notebooks none of them is correct.

                          3 flash is memory error. try with only one slot.

                              I already changed memory but the problem is that it doesnt power on at all. And without the battery it doesnt even light the lighnting bolt led.
                              I think its somewhere near the power ic and it can get power from ac adaptor and cant charge the battery

                                  Can it be something that has to do with giving power 1,8V to ram ?
                                  What should I measure to check that?

                                              Thanks atsio. I will start searching with those schematics.
                                              It's not the exact but most of components are match.

                                                  Canon G3430 has a lightning flash after the firmware
                                                  by zoltor
                                                  Good afternoon. The Canon G3430 is lit by lightning after the firmware, it does not respond to the buttons. I did not flash it, they brought it with traces of soldering, and all three chips. SPI - IC401 25Q128, IC402 25Q32, IC403 M24128. The SPI flash drives may have been confused in places. The QM8-0985 formatter. I've tried all the firmware available on the Internet, and the result is the same. I ask you to send dumps of chips, if someone has the same revision of the board, also tell me if the location of the SPI flash corresponds to the position numbers. Thank you very much in advance.

                                                  Hello,

                                                  I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
                                                  The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).

                                                  I have a CH341A programmer and I already attempted the following steps:
                                                  1. Identified the correct chip (W25Q128, 3.3V SPI flash).
                                                  2. Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
                                                  3. Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI
                                                  ...

                                                  Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
                                                  Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
                                                  The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.

                                                  I think my best shot is to figure out a way to read the internal flash memory outside...

                                                  HI guys

                                                  I got here a Sony 65X950G - I tried to find any repairs guides for this model but not many online

                                                  here is the issue
                                                  I have Sony and android logo. but then 4 led red flash lights front of the tv

                                                  I have 3.3v ref. 12v reg then T con 12v when I press the power on button
                                                  but then I get black screen and 4 red flash light at the front LED
                                                  but I get 3 led flash on the LED driver board.

                                                  I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
                                                  so I tried...

                                                  Hi there!

                                                  I have this Samsung LE32A336 TV that when you turn it on, it works fine for a second, then backlight flashes off/on for 3 or 4 times, and then definitely off until you turn the TV off again

                                                  I guess the BL driver is "trying" to keep it up and sees either lower or higher current flowing to the led strips, but just to be safe, is there any way to identify if the problem is in the led strips (open or shorted LEDS) or in the BL driver IC before opening the front side?

                                                  Thanks a ton!
