The Schoolboard has what are called "GRID LINES" that can open up and cause dead spots on the Schoolboard.
If you a cabled connection, try to test the Schoolboard that way.

Bosch Dishwasher Model # SHU53E02UC/14 started running about 3 times longer than it should and its not cleaning very well.


If the Rinse cycles completes within the normal time, but other cycles are slow - particularly a Heavy or Super Scrub cycle - it is most likely that the water heating is not happening or is very slow. The control will not advance (proceed) the cycle until the temperature sensor signals the control board that the water temperature is correct. Otherwise the control will wait, indefinitely, for the heating to happen. This also affects cleaning and drying performance. Loose wire connectors, bad heater, bad temperature sensors or a bad controller are possibilities.

First check ALL fuses,,,,make sure there good,, then check,Computer or wiring to the computer,,,sometimes where the wiring harness conects togeather they will break or loose connection,,or back out of the connector,,,,feel the wire just behind the connectors see if its broke, or loose or backed out of the connetor,,,very time comsuming ,,also the loom going to the throttle body,, check for naked wires touching around/ going to throttle body

Our KitchenAid Electric Range display panel keeps indicating to set probe temp (and beeps every time) when probe is not even plugged in oven. When placing the probe in the oven jack it feels very loose. ...


Hi

This means a loose/broken wire on the oven temp sensor or the oven temp. sensor itself is bad and should be replaced. To solve this issue test the oven temp. sensor, it should read between 1080-1120 ohms, if the rating is more then that and the door appears to be closing fine then it is the control board that is bad and should be replaced. Hope this helps...please post back for further assistance.

The gauges are not working and the fuses on the inside panel are good


Not much to go on but here goes;;;The most common thing is the ground wire on the printed circuit behind the instrament cluster,or a broken circuit board. next,check to make sure the wire harness has not shook loose going into the cluster. then theres the wire harness that goes through the fire wall,,that could have a bad conection,,there is also in some vehicles,,a voltage regulater just for the cluster,,,and then theres that nasty computer that controls all the functions of your engine and sensors. My guess would be the circuit board first then a bad ground on the circuit board . A word of advise,,,be sure you checked ( all ) the fuses with a ohm meter and not a test light ! A test light can destroy your engine computer. And sometimes the fuse can look good but still be bad. Also ask your dealer if there are any hidden fuses that you cant see. They sometimes put them in strange places. Hope that helps !!

Bluetooth/wifi doesnt works


Same problem occured at HP laptops. Unfortunate, problem comes from the board. Somewhere has got crack or broken link. Last time I have checked, I find , Top of the board and bottom of the board has got copper lines and devices soldered, but there is also middle lines that not possible to access and repair without shematic diagram. I end up changing the board that solve the problem. But Before that I install driver, restore again (seems worked forawhile) remove the wireless card check solders, setup network again. None worked. I do not want to give you bad feelings but, if it is Vista, reload the drivers and see if will work.
Hopefully it will. Do not touch the switch much, there are P.O.S. Small spring inside the switch is loose everytime and it is not gold plated, get rusty couple of months. Goodluck

I have a Pioneer KEH 2700R and when i press the on button it doesnt turn on all wires are conected and unit does works as when i puss and hold the function button it all lights up


It is a loose connection or cold solder and cleaning problem this is the main caused. Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

Good luck:
