18 month old LG 43" LED TV. Screen goes dark, but can be seen if you hold a flashlight up to screen. Sound is fine.


The inverter supplies the voltage to activate the screen. There are usually 2 boards, a slave and a main board. Sounds like one of them is leaking voltage and causing the screen to go dark after the initial start up. Make sure you didn't joggle something loose while you were replacing the power board check all connections. GL

Trying to make my seagate barracuda 7200.9 slave


1) Open your computer case
2) On the back of the drive where the connectors are, you have jumpers. These small plastic tabs change the function of your hard drive. All hard drives have a special setup procedure. The information about jumper settings is on the top of the hard drive.
3) Remove plastic tabs and put them according to "Slave" instructions.
4) Connect drive to middle connector of the cord.
5) Connect power supply cord.
6) Secure the drive in place and close computer case.

Also make sure that the main drive is not set as slave.

Can I add an additional internal hard drive?


Hi,

Yes, you can add additional hard drive.Please follow the below steps to add the drive sucessfully.

STEP 1:

Make sure you have room for an extra hard drive, here's one way to do this:

1. Restart your computer and go into the BIOS menu as per below instruction.
Steps to enter BIOS:
After turning ON, immediately press the F10 key if your computer was built in 2006 or later (came with Vista). Press the F1 key if your computer was built before 2006 (XP or earlier). Press the key once every second until a BIOS Setup utility screen opens.
2. Go to the "Standard CMOS Settings."
3. In this menu, you will find four settings labeled as follows: PRIMARY MASTER:, AUTO/PRIMARY SLAVE:, SECONDARY MASTER:, SECONDARY SLAVE:. Change all fields to auto detection.
4. Reboot your computer.
5. On the first or second screen, you will see something like the screen above and it will say detecting (drive(prim/sec)) : (name of the drive if present). If any of them say none, remember which drive it is. If all of them have a drive name, all your bays are filled and you can't add a new hard drive without removing a disk drive or hard drive. Consider making an external USB drive.

STEP 2:

1.Shut down your computer.
2.Unplug all of the cords from the back of your computer and pull the computer out from the desk.
3.Remove the case screws. If you're having difficulty, it's a good idea to consult your manual on how your particular case is removed. Put the screws in a safe place so you don't lose them. Remove the side panel and place it out of the way.
4.Find the area where all the flat ribbon cables (or SATA cables, which are smaller and usually red) connect to the main board. Find the cable that corresponds to the free drive either primary or secondary.

STEP 3:

1.Set the jumpers so the drive knows whether to act as a master or slave. The jumpers are the set of pins on the back of the hard drive. They'll have a couple of rubber or plastic blocks covering some pins. Find the diagram or instructions for your new drive on to set the jumper for the master/slave.
2.Find the empty bay in your computer case. Using the screws that came with the drive or computer case, mount the drive.
3.Connect the cable to the hard drive. If it won't go in, make sure that the safety bump is aligned with the hole.
4.Connect a Molex power cable, (a smaller connector with red, yellow, and black wires.)
5.Put the side panel back on the computer and put the screws back in.
6.Plug all of the cables back into the rear of the computer, and connect them to their power sources if you unplugged them.
7.Boot up the computer. Go into your BIOS at startup.Check the BIOS auto detect to ensure the second drive is detected. On the screen that shows that primary master/slave,secondary master/slave you should see the name of your new hard drive.


Thanks & Regards
Rizwan.

My pc beeped twice and nothing came


Lack of video signal is usually 1 of 3 things, Power supply (PSU), Video card or Motherboard (mobo).
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #1A: You might get some power lights coming on and some fans spinning but the video output does not happen, usually indicates that motherboard or PSU is going out or has gone out. Occasionally it will be due to a weak (damaged) PSU.
Situation #2: If you get sounds (normal Windows startup sounds) and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat (take out and then put back in) try that. If it is onboard video then you may have to buy a video card for it.
Also take this time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The bad caps will need replacing to fix (not a job for an amateur). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.
A few years ago a company stole the recipe for making capacitors and started making their own capacitors at really cheap prices. The stolen "recipe" was not complete and not correct so these caps started failing after about 2-3 years of use. Emachines, DELL and Gateway were the computer companies most affected by the bad capacitor issues, although any of the big companies could have the same problem. These bad caps also affected power supply makers.
Do you hear anything else during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better. Do you have the 4 diagnostic (A,B,C,D) on the rear of the machine? What is the front power light on the CPU doing?
