    e470i-a0 acting crazy

    Did a Reeceyburger led repair on this a couple of years ago and it quit my daughter a year ago so I assumed it was another led so it has just been sitting. Got it of the shelf yesterday and plugged it in and back lights came on. Started checking things over and saw an lvds ribbon cable that looked a little off so I reset it and got picture and sound on air antenna.

    After about an hour the sound quit so powered it down and back on and got sound again. a while later no sound and no picture, but had back lights, and was getting the no signal message.

    Remote, or tv buttons were not responding completely. Could get it to turn on ok but no signal. If I hit menu, the no signal message would disappear but no menu. Also, when you push the power button to shut down, it takes awhile to finally shut down.

    Checked power supply voltages and appear to be producing what is needed. Only thing I am not sure of is what the led volts should be. Getting with
    plug connected:
    led1:21v
    vout1: 107v
    led2: 21.5v
    vout2: 109.9

    Unplugged:
    led1: .0850v
    vout1: 128v
    led2: .001v
    vout2: 128v

    Any thoughts or ideas? Main board took a dump? Thanks

      Did you try a factory reset?

          I can't get into menu. it just goes blank and locks up. I tried the smart button on remote and it brought up apps for netflix, youtube, etc. found an app on there that said hd settings and it brought up a menu to reset to factory so I did that and now TV is stuck on the vizio logo. Have to unplug to shut off. Possible EEPROM?

              Wonder if its a bad solder joint or faulty capacitor? could try heating mainboard with a hairdryer, small sections at a time, see if anything changes.

                      Ended up getting a main board for the TV and it is up and running.

                              my Xiaomi Notebook Pro X laptop fans work like crazy for no reason
                              by sda sad
                              Hope this is the right place, someone can help me.
                              My laptop started having a really strange problem....
                              When I turn it on the fans start working at a crazy rate and with random breaks...
                              They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
                              And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

                              The model of the computer:
                              Xiaomi Notebook Pro X 15 OLED (A30)

                              Macbook Core i7 2010 a1286 820 - 2850A CRAZY JUMPING voltages
                              by marce002
                              Hello

                              Need just to know how do you guys determine what the problem is, when we have some fluctuating volt, to discard a faulty TPS 51125 , or if the issue is after this IC.

                              CRAZY JUMPING

                              PP3V3_S5 = 0v to 3.33 v jumping
                              PPBUS_G3H = 12.4v to 12.48 jumping a little
                              PP5V_S5 = 2v to 5v aprox, jumping fast
                              P3V3S5_ENTRIP = crazy jumping from low volt
                              SMC_PM_G2_EN = jumping 0v to 3.3v crazy


                              STEADY

                              P3V42_G3H=3.39V steady
                              PP5V1_CHGR_VDD=5.06v steady
                              PPCHGR_DCIN= 18.29 to 18.31 jumping
                              ...

                              Lenovo Tab 2 Pro display "going crazy"
                              by paparazzo79
                              Hi guys
                              I got myself Lenovo TAB 2 Pro at Friday.
                              I did used it whole Friday just to test it and it was working normally.
                              I installed few apps and charged it via regular USB 3.0 port on my laptop.
                              After that I noticed that tablet behaves like it has a virus.
                              Suddenly it just registers touch input, byitself starts to exit from tabs,volumes up or down,freezes,when press home key does not register etc etc..
                              I remember I did cleaned it yesterday with isopropyl but I put the alchocol on dry cloth and cleaned the screen and metal housing...
                              really few...
