SOURCE: Need schematic diagram, some advice and ultimately replacement parts

You have something in short circuit in power supply pattern, so filter coils are burnt. It may be voltage regulator, or regulating transistor, electrolytic capacitor or even shorted diode at pwr. input serving to protect in case of inverse polarity applied. Check all for short. Was it reverse polarity or overvoltage occured?

Believe it or not most of the components of the Acer laptop screens are the same. However that is a problem because 90% of the screens are integrated circuitry not easily replaced. Most of those parts aren't sold seperately. My suggestion if you want to keep the laptop is remove the old screen in whole and replace it. It will be cheaper in the long run and easier.

I have a Yamaha PSR 2000 keyboard. You can not see the keyboard. It lights up but you can not read anyting on it. It is blank. Can it be replaced what part would one need to fix the problem? I had scr

If you have a light behind the screen then the backlight is working. It could be a connection from the board to screen but this is very unusual.

These screens have been know to fail and will need replacing.


The screen is not a simple and requires an extra driver board and various components to be replaced/changed. You will need soldering equipment for surface mounted resistors etc if wish to undertake this.

The replacement kits including the screen cost around £ 400.00

Have you tried a factory reset?

Hold down top / highest white key whilst turning the keyboard on.

Good luck

Check engine light produces a p1155 and 1135. both say same thing open ground, heater control circuit failure PCM failed but for bank 1 and bank 2. not passing emissions.

Do you have a wiring diagram(s)? Find one,if not.
All data is helpful,but they charge $26.95 for a year.
Free is better.
Check for recalls on your model. NHTSA.
Check PCV and EGR valves for leaks,vacuum booster and...More.
Circuit voltage on harness side,not with an ohm meter at component.
You may need a more expensive diagnostic tool.
Get into an Avalon forum to see if that code has been difficult to diagnose.

Power window

Now you need a factory wiring diagram & do some testing

eg: voltage drop your way from the battery or back from the motor,
until you find the open in the circuit or failed component

You say you HAD the switch checked
Are those same people not capable of finding the issue?

If you had a fault in your neutral wire the voltage may have raised to near 220 volts and fried the circuitboard. Replave the circuitboard or replace the thermistor on it. Double check the voltage and the connections where it is wired under the dishwasher.

Repairing Yamaha psr-12

If the power adapter is not the original adappter- check to make sure the polarity is correct- it should be marked on the keyboard near the adapter socket, and also on the adapter itself.

The keyboard should have an internal fuse- check that. Then with keyboard open, if the fuse is okay, trace the power flow from the power pack and look for broken wires, bad solder connections, stressed components like bulging capacitors, etc. It may have a burned out zener diode in the power supply regulator portion of the main circuit.

Yamaha psr-280 flashing display no key response or sound. Is it dead??

Your adapter should be a 12 volt DC delivering 2 amps (2000 ma). If the adapter is too small, you will have the symptoms you are seeing. Make sure the polarity is correct. DO NOT use the so called "universal adapters".

PSR-2100 need to find replacement circuit board.

I don't have a parts source for these other than Yamaha. Call them up to get the part number for the board. The sound is usually sent through the headphone jack which acts as a switch when you use headphones. Replacing that board should resolve your problem. If the board is no longer available, it is possible to repair the existing one, but this is a specialty task and not one I would recommend a novice attempt.

Please keep us posted on your progress,

I do not think that the problem is caused by the broil element, but I cannot rule that out. I believe there is a short or an open in the circuitboard. Unless you find the short or open you will need to replace the entire control board.
