This is likely due to a failed power supply. Replacing the power supply board should solve the problem.

You can fit the picture to the tv screen by clicking the buttons on the receiver. Change the setting to 1080i from 720i. It is going to work like that.

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

What does power down pc and plug in cabkes for gpus mean, even though they are already plugged in bad card?


Added a new graphics card? Today, high-end gaming graphic cards (GPUs) need separate power from the computer's power supply; they take more power than the motherboard can give them through the connector under the card. Your power supply should have separate connectors that match what's on the new video board.

Shut your computer down, pull the plug, open it up, and connect the power supply to the card, and then you'll be fine.

Hi! there anybody help my power generator won't powering on i even replace the spark plug but to no avail i mean no luck I've try so many times to pull the string for starting up but no luck and even reset...


Take the spark plug out, connect it back to the wire, and rest it so it is touching metal, Pull the cord and see if you see a spark. If you see a spark that means you are not getting gas. Put a few drops in the hole and replace the spark plug. Pull the cord with the choke off a couple of times and it should fire up briefly. If this is the case you will have to clean out the bowl and gas supply lines.

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You don’t have to bend up the electrode.

These flood easily and are very difficult to start once that has occurred.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
Hope this helps

Cigarette front lighter is not working in my 2001Saab


Check ALL the fuses. pull them out an dlook. Also repace the one that is power for the dash/rradio/etc... even if it looks good.
If that doe snot fix it then pull the lighter out and test the wire going to it for power. If it has power then you might have a bad plug/ground. Replace outlet if so.
