Following a power cut, my HL2142 has all lights flashing. Can't fix it. Help.

yes you can fixed it replase cover and and cut hdd and buy new rak out side and conected the new rak with hdd that is very esy

Try this link. It has helpful troubleshooting methods.

The code that is flashing usually points to a main board failure. I would recommend getting it diagnosed. If you want to be gutsy and try and replace the main board yourself, MAKE SURE YOU GET A BOARD THAT MATCHES YOUR PART # EXACTLY. Sharp makes several revisions of main boards for various models, and they ARE NOT compatible.

I have just fixed an Aspire 7250 with following symptoms: Only blue Power LED or battery charge LED come on, fan spins, no backlight, no video either on internal screen or VGA output.
Problem solved desolderig BIOS flash chip (W25Q16) and flashing BIOS 1.10 with an universal programmer.

It's a dead motherboard. I apologize. It's not worth fixing.

as per your report we understand that there must be something wrong with boiler/hear or with the heating sensor. So that when you try for hot water because of safety reason it gets automatically switched off. Please rush near to your service center as we do not advise you to fix this issue.

If the machine detects an error in the fixing assembly, the DC controller PCB operates
as follows:
[1] It causes the FSRDRV* signal to go '1' to cut power to the fixing heater.
[2] It causes the RLYDRV signal to go '0' to turn off RL1, and indicates 'E000' through
'E004' on the LCD in the control panel.

When 'E000' through 'E004' is indicated, the NVRAM on the DC controller
PCB remembers an error in the fixing assembly even when the
power switch is turned off and then on. After turning on the power, be
sure to execute the following in service mode to remove the error information:
#7 PRINTER > #4 PRINTER RESET > YES = (*).

I had the same problem. We watched a DVD, and the unit worked fine. We went out for ice cream, came back, and decided to watch a VHS. Instead of taking the VHS, the CST.IN light flashed and the unit cut off after a few seconds. We didn't have a VHS in the unit at the time. After cutting the unit back on several times without success, I looked online for solutions. One person said to hit 'eject' 5 times in a row, but that didn't work for my unit. Someone else said there was a lever inside near the power button that ejected the VHS, so I checked that out next. I washed and dryed my hands well, and used my finger to jiggle the white lever. Then I saw that the tray that the VHS sits on wasn't all the way forward, so I gently pulled and pushed it. I'm not sure which of the two actions worked, but my light is now a steady green and my unit is working fine now. I am so glad because we've had this unit for almost 10 years now, and I really didn't want to have to buy a new one! Good luck!

do any lights flash etc, if so check below;

• The auto-off setting is turned on, and the console has been inactive for six hours.
• The console is too hot.
• There is a problem with the power supply.

1. To begin troubleshooting this problem, check if the auto-off feature is turned on. To check if the auto-off feature is turned on, follow these steps:
   1. Start the Xbox 360 console without a disc in the disc tray.
   2. In the System section of the Xbox 360 Dashboard, select Console Settings.
   3. In the Console Settings area, select Auto-Off.
   4. Examine the option to see if it set for auto-off. If it is set for auto-off, change your selection.
2. If the auto-off feature is not turned on and this is the first time the Xbox 360 console has turned off unexpectedly, let's do a simple test before we continue troubleshooting.
   
   To do this test, turn the Xbox 360 off for about 10 minutes. Then turn the console on and see if the problem occurs again. If the Xbox 360 console turns off unexpectedly again, make a note of how long the Xbox 360 console is on before the console turns off automatically.
3. If the auto-off feature is turned off but the problem happens again, check the appearance of the Ring of Light to determine what to do next.
   • The two lights in the left quadrant of the Ring of Light flash red: The internal temperature of the Xbox 360 console may be too high. In this case, turn off the Xbox 360 console, and let it cool down. It may take several hours for the console to cool enough.
     
     Also, make sure that the ventilation openings on the console are not blocked. (For example, the ventilation openings may be blocked if you place the Xbox 360 console on a soft surface, like a bed or a sofa.) Also make sure that the console is not located in a poorly-ventilated place, such as an enclosed bookcase or stereo cabinet.

   • No lights are flashing on the Ring of Light: In this case, we should check the lights on the Xbox 360 power supply for hints on how to fix the problem. A green light indicates that the power supply is correctly functioning.

The sony warranty repairman came by this afternoon and checked my KDF-60XS955 for the blinking green light that cycled the picture and sound on and off about every thirty clicks or seconds. After checking a couple of things he said it was the lamp XL-2200 or the ballast. chrismickey
