Hi, I don’t know what the repair cost would be, but it seems that it is a common problem with your model series. Here’s a video that shows what is involved in trying to fix it yourself, if the problem was as shown in the video and not a faulty display screen. Getting a professional to fix it would involve labour costs for the time spent etc or if the problem was in the display screen itself then the whole unit would have to be replaced which would involve parts (examples only) and labour. Although a dealer may be able to source parts cheaper and they’re paying their mechanics anyway Hopefully this is of some help.

Hi @aksal60 , According to the service manual a 9 blink error code indicates a problem with the TU board (tuner board). The manual is for both the 55” and the 65” models Here’s a poor image of the blink error code chart and the location of the TU board. (click on image to enlarge for better viewing) The service manual can be viewed for free online but it is low resolution, so some sections are hard to make out. Also there are no schematics in the manual. To download the manual you have to pay for it. To move through the manual you have to select the appropriate page number below the document and click on Go. There are 127 pages in the manual. Page 71 of the manual shows the location of all the screws that hold the back cover. Hopefully a start.

Hi, Don’t know the answer or the machine but did you recalibrate the machine after replacing the motor capacitor as mentioned in the [documento: W10280489 - Tech Sheet] you didn’t say? (see p.5 Calibration mode for details) Also does it pass the other test modes OK e.g. tachometer verification mode, shown in the tech sheet as well?

Hi @ras4442015 , You can buy compatible chargers (examples only) that are suitable for the phone. There are other suppliers online that may suit you better. Just search for ZTE Z982 charger, to get results If using one of these doesn’t solve the problem it may be a problem with the charge port in the phone.

Hi @kath8fish When the laptop has been turned on do you get the Windows startup sound, indicating that it has booted into Windows? If not, try getting into BIOS on startup by pressing the Novo button on startup and check if you can get into BIOS with images on the display. If so, try shining a torch at an angle close to the screen and check if you can detect any images at all. If there are images to be seen, then there is a backlight problem with the screen. It may be that the spill blew the backlight fuse on the motherboard. Usually the fuse is mounted close to the video cable connector on the motherboard, so you may be able to check it with an Ohmmeter to see if it is OK or not. If the fuse is OK and that there is voltage at the fuse when the laptop is turned on, then it may be a problem with the display itself. If there is no backlight voltage at the fuse then the problem is on the motherboard. Check for any damaged components due to the spill. If there are no images to be seen, then try connecting an...

Hi @frnw , Have you checked if the power outlet is OK? It may be a faulty switch in the outlet. Try connecting to another outlet. Also if the TV is connected via a powerboard (powerstrip?) connect it directly to the wall outlet if you have proved that the wall outlet is OK The power board sends a voltage signal to the mainboard when there is power connected to the power board and it is the mainboard that turns on the Standby power light if the signal is the correct value. If the power outlet is OK you would need to check the standby voltage on the power board first to determine where the problem is.

The 3rd wire from a battery is usually connected to a thermistor attached to the battery which signals the temperature (resistance value changes with temp) to the battery management circuit in the motherboard.

Charging will be halted to if it got too hot before being fully charged, which may create problems e.g. a fire

If leaving the 3rd wire disconnected, the battery should not be left unsupervised whilst it is charging

Hi @captainsnowball ,

FYI

voilà French exclamation - meaning “There it is!” or “There you are!”

The “red thing” in Step 3 is most probably an IR filter, to filter out visible light to improve IR operation
