    Bush 26" BLCD26H8 stuck in standby

    I aquired this TV for £10
    Stuck in stand by with red led on, all PSU voltages fine.

    Have tested the following.
    1. all push button switches with a meter back to the main A/V board (all read < 1 ohm)
    2. tried powering on with remote and 2 other URC's including the Sky 9f (NO Joy) just incase the remote provided was not the correct one.
    3. forced back light on (As theres no bkon signal from A/V) and lights up fine.
    4. PWON signal is ok and down turn PSU on/off (tested disconected from A/V)
    5. theres NO PVC on the PSU - tf is not fitted

    The small PCB with the PSU is a step inverter for 12v to 24v to power the backlights (Works fine)

    At this point i'm stuck, was wondering if the eeprom on the AV board is screwed. does any one have a copy of the eeprom for this TV. Any pointers on fault finding on the AV PCB, Any known faults for this model ?

    Any other sugestions welcome.

    PCB numbers as follows

    PSU IPB731 Rev 1.3
    Main A/V T.MSD306.69A.11345
    Ean of TV is 5060237230156

    Re: Bush 26" BLCD26H8 stuck in standby

    i would say eeprom, i had the same probs with a JMB set, and ended up replaceing the main board, with one from a baird set, and it fired up with no probs, but be warned, i can't get any remotes to work it now, and the touch buttons did not work as they should, i had to swap a few wirs around on the plug to the button board

      Hello

      I have an TV Led 4K Selecline 65s18 with mainboard T.MS3458.U801

      The TV is faulty with stuck in Standby RED LED. Can't power the TV.

      Before this problem , the TV stuck the picture with artefact , i unplug the AC cable and since the tv is stuck in standby .

      All voltage are OK on PSU and main board for regulator. I tried flash firmware 25Q64 with many dumps

      But the voltage on power button is 0.6V not 3.3V. When i press power button the voltage up to 0V. I tried to add 5V with Power Supply on 5V_STB and 3.3V on Power...

      I enclose the psu diagram, after the first routine checks I find myself with a regular standby voltage of 3.3v blue light on steady when the power button is pressed nothing happens, psu disassembled and bench checked ... forced ignition by sending a signal 3 , 3v on the SW and PWM2 pins the psu turns on and delivers all the voltages...

      LG 32LB1R - stuck in standby mode
      by lego1234567
      Hi. I have the following problem with my TV. After connecting to mains, the standby led (red) turns on, but TV is not responding to remote control or buttons on TV. After some measurements, I found out that +5 V standby voltage is present, but I dont have ON/OFF signal coming in to turn PSU on. It stays at zero volts. After looking at the schematic of the mainboard, I should get ON/OFF signal coming in at the R1402 resistor, but it stays around +3,5 V. So I removed it and I was able to turn on TV with buttons on TV, but not with remote control.

      What could be the problem ? Thanks...

      93C46 and 93C56 EEPROM
      by SidneyCanadas
      I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

      https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

      Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...

      Hi all,
      First time trying to fix a TV for a friend, it's a Bush DLED32165HD.
      Power Board - 17IPS11
      Mainboard - 17MBS82S
      Panel - VES315WNDB-02

      Red blinking standby light is on steady, press power button on remote and light flashes 7 times then stays steady, press power on remote again light flashes 10 times and then goes off.
      Checked all the voltages on the power board inc backlight circuit, they all read ok and are stable. Backlights tested with backlight tester and all work fine (2 strips x11LED on each).
      No picture, backlight or sound just blinking...
