If the screen does not come on but you still have audio, then the backlight controller is faulty and nedds to be repaired. You can try shining a torch close to the screen and look for a dim picture. This will verify that the backlight is faulty.

2006 Mazda tribute. How can I check the power at the door lock seems like it's backwards does anyone have a wiring diagram or testing procedure thanks in advance

Not sure which door you are on but looks to be right side front or rear. You should have continuity to ground on both wires to the lock motor when no button is pressed. Should get power voltage pulse to Pink/Orange wire when unlock button pushed. Power voltage pulse to Pink/Black wire when lock button pushed

Hej Ross ,u seem to be quite the expert on krups expresso machines.I have a 8010 model that was leaking.I changed the rubber seals but now it makes that start up check and it keeps saying there's a fault...

It has to be one of the micro switches either not being activated by whatever touches the switch button to switch it or the switch itself is not making or breaking the circuit. You will need to carefully check your assembly, there is the possibility to not get things exactly as they need to be or maybe something has been bent or damaged during the repair process. There is no chance to delete or bypass the switch, the pcb will always be looking for a pulse from the switch so removal is not an option. If you put jump wires to a multi meter one switch at a time and then run the machine you should be able to first find the switch that is not pulsing and then once you are looking in the right place figure out why that is so. EA8010 is not a model we have in my country but we have had earlier versions which must be very similar.For me this sort of testing is very easy because I have extra outer housings with huge cutouts so I can operate and inspect at the same time. For you it is not going to be so easy.

LG 17LX1R flashing red LED - TV won't power up

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Monior doen't power up, I suspect the powe supply is faulty. The on / off switch on the front of the monitor seems to pulse (the light) but failes to startup.

perform a power supply inspections. First, trance the cables that connect to the Tv and power curcuit outlet to firmly attach dittached power AC cords. Also, check on the power outlets power button status to switch on when detected as off. Once achieved, the Television is ready to be powered on to display media. Important notes includes awarenes that recent TVs have two power on functions. The TV may require manually powering on the press buttons. Also, the second power features are situated on the Tvs remote control. press firm ly the remote control power button to display the initial television screen logos.

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Unplug for several hours, press and hold power button for 5 seconds, wait half hour more, plug back in and try. Or press and hold either channel buttons at same time or volume buttons at the same time to see if that exits the mode.

Touch screen and push buttons are not responseive.

Make sure the switch on the side that locks the buttons is not switched on. To be safe, switch it on (so that the red shows) then off.
