There is a circuit in the power supply that shuts it down if there is an over current condition. Over current is generally caused by a motor being jammed or a short. Open the plotter and manually move the mechanisms driven by the motors. Look for binds or broken parts. If the printer has had service recently, look for pinched cables. It is possible the power supply is bad, also.

My matsui m32lw509 TV standby light flashes once when i turn it on then it just stays blank nothing powers up ???????????????


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

Red light comes on nothing ells


The Designjet 1050C Plus does not need the hard disk drive to boot. When only the red light comes on, the firmware ROM is probably missing. Open the small panel on the back of the plotter to access the memory and ROM slots. If the FW ROM and memory are missing, you will need to buy them to make the plotter boot. They can be purchased at: http://www.lpscomputer.com/c-654-designjet-1050c-1055cm.aspx

My HP DesignJet 450c InkJet Printer wont even power up at all. I even had a 2nd power cord & tried this, still nothing. I also tried a differnt outlet, nothing. Any suggestions?


I think the problem is not on your power cord. You may have problem in the Electronic Module which is located at bottom of right side of the plotter (inside of cover). First, you have to remove all other cables except the control panel cable connected to the Electronic Module. If any light does not turn on when you plug in the cord and turn on the power, you need to replace the Electronic Module. If the light is on, then you have some other problems. You can perform the repair by reading page 8-13 & 8-14 and other related pages in HP 430/450 Service Manual.

I have a problem with the remote control that is not working, I have taken it local technicians but nothing . My TV is in child lock so I need a remote for the tall big telefunken TV


Hi what you can do is to buy a universal remote control for this TV to remove the child lock. You can get that online or on any electronic shops in your area. Once done here is the instructions on how to remove the child lock using remote.
Look at the "Power" indicator light on the front of the television to check if it is blinking. When blinking, the child lock is enabled. You can also check by pressing the "Power" button on the television.
Point the remote control at the television and press one of the buttons on the number keypad. The "Power" indicator light will stop blinking, indicating the child lock is turned off.
Lock the television again by pressing and holding the "Power" button on the remote control until the indicator light starts blinking. It takes approximately three seconds before the light turns on. Thanks

Sony KV32FS120 Trinitron TV No picture or sound when power button on remote is turned off. Red light at front of TV blinks nine times per cycle.


Hello,

Once your television blinks about 9 times then it means there is a problem somewhere most likely the lamp of the television. Another source of this problem is also a bad capacitor from either the main panel or the power panel.

If your remote turns off actually it is because there is nothing to operate on the television, so once your television starts the blinking light, the remote will not be able to operate the television, once you unplug the television and plug it back then press the power button, the remote will do the same.

Until the television is fixed is when the remote will work normally.

Take care and good luck

450c color problem


The 430 ID is B/W, you need to load the 450C driver to get color, renaming the driver isn't enough.

Dishwasher almost fixed but won't pump water


Could be the motor is stuck. This is a common problem in dishwashers. With the power turned off, open the front kick panel and turn the motor a couple of times by hand. Then turn on the power and run the drain cycle to see if the motor drains properly.
