Re: Ghosts

Hi John.
Seen a TV remote control emitting commands by itself caused by a nearby idle cell phone.

Re: My Toshiba is dying help...

Could i take my HDD out and have it scanned on another computer ? even tho my AV says it's clean ? I believe you can as a secondary drive, not booting from it. Windows does not like to boot in a planet where it was not installed. But am not an expert... Someone else will confirm or knows a trick. B...

Using a 'live' CD/USB to boot Linux from, without alteration to the -still present and connected- sick hard drive allows to tamper, delete, modify, erase, repair, fix anything in the sick hard drive; and to save to any external device the precious data, programs, that got impaired.

Re: LED backlights in LG television...

Anything smaller than 40" is not worth repairing ... That size is less fragile; the dismantling part is less risky. Larger than 40" have a higher price sticker, worth repairing; if dismantling/reassembling goes well. Smells like the cost of the repair bill is more driven by the price of th...

Re: LED backlights in LG television...

Thank you, Tzap. After looking at some dismantling videos and closely inspecting how this LG 50LN5400 is put together, decided to NOT do it the way everyone does it. Good thing ! Handling such a large thin LCD and keeping it safely and lint/fingerprints-free aside until replacement emitters arrive w...

Re: 18 Volt Sub C NiCd Battery Packs (1.2 x 15)

NiMH are replacements for NiCd. Same charging protocol, same charger useable. That was the point, to canibalize the PorterCable or any battery to use their cell packs in your application. BlackDecker have that offset centre row geometry too. Shown here ----> https://www.youtube.com/watch?v=NPH11WVHp6o
