SOURCE: cect p168C will not power on

  1. Turn iPhone off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
  2. If that doesn't work, connect it to the iPhone charger and let it charge for at least 10 minutes. Note: iPhone 3G does not support FireWire and will not charge from any FireWire-based power source.
  3. If that doesn't work, toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image. (see "Display has no backlight or dark screen" below for further troubleshooting.)
  4. While connected to the iPhone charger, try to reset the iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until either the Apple logo or battery symbol appears. If the battery symbol appears, continue to charge iPhone until it is fully charged.

SOURCE: When I press the power button LG displaying chars for 1 second

Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.

Unit is now working fine.

SOURCE: Can't restart, can't connect

I had a similar issue w/lacie ethernet bigdisk 1TB. Couldn't access drive, found that it was making the clackety clack drive death sound and was hot to the touch. Powered down and tried to restart but no blue light, apparently dead. It always ran hot. Pulled drives and connected directly to computer w/sata connector, drives tested good. Put all back together but still didn't work. Put in freezer overnight, pulled out and hooked up - was able to get blue light to come on but nothing else, no ethernet lights. Strange, the blue light would come on when I plugged the unit in, I didn't have to press the button, nothing wrong inside of case, but unit not really functioning. Also, as you said, I could only turn the light off by unplugging. FIX: As a last resort, I pulled the circuit board, baked it in the oven at 360 degrees F for 15 minutes, preheat oven to 360, immediately took the board from the oven to the freezer for 15 minutes. Put back together and the dang thing works perfectly now. I soldered the fan to the internal 12v line so it runs continuously and now it runs very cool. My guess is that the controller had a cold solder joint somewhere. Hind sight says I should have returned it to Lacie for a new one, I think they would have worked with me even though I opened the case.

SOURCE: LCD monitor shuts down every after 2-3 seconds

dustcore025, Need a little more info here. Do you know age of monitor? Was it or did it display a "perfect' image on it the day before? Is it under warranty? How far are you willing to go to try and repair this thing? Do you know how to "part" the snap together plastic back cover from the bezel, after removing the pedestal? This sounds to me like a Switch-mode-power-supply or Inverter problem that occurs when some Electrolytic Filter Capacitors get a little bit TIRED of being constantly subjected to high temperatures near heatsinks that are used to keep semiconductors within operating limits. You can determine how bad this may be if you can do a test and remember what happens. Here is what to do. Make sure PC is fully booted displaying WIN desktop or some other screen. Next, with someone to keep hitting the CTRL or SP bar key every 20-40 seconds while you reconnect both cables of your MM17 back to the PC video port and ac outlet. Now try to turn on the monitor and note exactly what you see and for how long. Did it have a sharp clear image, even for 1-2 seconds? did the screen go black? OK! Next thing is to shine a bright flashlight onto the screen 2 inches away from where you know there was something a few seconds ago. Try it at different angles and not if you see anything. get back to me with results of test. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

SOURCE: press power button green light comes on.But no picture no sound,

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

Our Mitsubishi projection tv went out one day. When we went to turn it back on all it does is blink the green light for a few seconds and then shuts off. What could it be? Where can we look to see where...


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

The laptop was turned off improperly and the power light is on but there is nothing oon the screen


Try pressing and holding the power button down until the power light goes off.
Once it is off, then try to turn-on the laptop as usual.
If this does not work, remove the power cord and the battery from the laptop, and then press and hold the power button down for 30 seconds.
After the 30 seconds, release the button, install the battery and re-connect the power cord. Start the laptop as usual by pressing the power button briefly.

Power shuts off 1 second after tv is turned on


Good Day,

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.

3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.

I hope this was helpful, BIG IRISH.

TV turns on, then turns itself off about 2 seconds later.


set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

46" projection not coming on


You have an power supply problem & or a high voltage flyback transformer gone bad. The regulator is usually an STK followed by some numbers, located on a separate small board above the main chassis in the rear of the tv. The flyback is down on the main chassis & has a red high voltage lead wire coming out of it that goes to the high voltage/focus block.
