Gateway laptop i push power button it wont boot up but leds in front flash 4 times


Try holding down the power button instead of just pushing it. I had this problem with my HP dv7 and holding the power button down for around 5 seconds worked for me. Also make sure that its plugged in to a power source.

Hitachi 53UDX10B power button flashes, chirping noise, LEDs flash


The convergence issue might not affect the TV to the point of not turning ON.
The chirping noise you hear, it means there is a short circuit in the circuitry, possible the HOT or power supply assembly.

61uwx10ba. no power to any boards but power supply.


have you reched around the new soldering area carefully, check for solder spills or drops in the printed circuit, also another thing to look for is some of those replacement stk do not hold their weight, you might want to take them out and try the old ones to see if you recover tv power.

Replaced drum on Dell 1720dn printer. Where is


This should fix the drum light being on that 1720

Turn off the power using the switch on the back of the printer. Open the front door of the printer. Hold Continue button down, power on the printer, and continue to holding Continue down until the LEDs begin to flash. When the LEDs start to flash, release Continue button. The LEDs will continue flashing until only Error LED will be lit. Close the front door. Continue, Ready/Data, Toner Low and Load Paper LEDs should be lit. Wait till the printer completes the POST process. POST is complete when fan noise and rollers stops. After POST wait for 5 seconds Press Cancel button 4 times slowly until the Toner Low LED is lit. This is the procedure resetting the counter. Press and hold Continue until all LEDs begin to cycle in sequence, then release Continue. Now only the Toner Low LED will be lit. Cycle the power of the printer: Remove the power cable - Wait for 5 seconds - Plug the power cable back to the printer - Power the Printer on.

It's not coming on probably because the safety sees a short and is sparing you smoke damage. Double check to make sure any solder didn't cross or drop to another set of solder joints on the bottom. You might be able to get a service manual from here that could tell you more about the lights -> https://www.manualsparadise.com/ShowProductsForModel.do?model=M22931911
