Flickering tv screen on Samsung 40”

My Samsung LN40” has been flickering for a week. Progressively worse.

I’m trying to locate the correct wire to cut for my specific model. I’ve spent hours on the phone with Samsung with no feedback. Please advise. Thank you

Wiring 40 or 50 LED's to 12V motorcycle battery?

I would like to wire 40 or 50 LED's to run off of a 12V motorcycle battery.  Here's what I have: Red LEDs- 2.2V typ 2.8v max @ 20mA Motorcycle battery- 12 Volt, 10 Ah, 180 CCA The plan was to run 8-10 series of 5 LED's in parallel. From what I understand each series would need a resistor but I am not sure if the motorcycle battery puts out enough mA to support the total number of LED's. I am a beginner so I may have this all totally wrong, hopefully someone can point me in the right direction. Thanks for the help!

How to run (and power) 40 16' LED strips with a single controller?

I am working in a room with an exposed beam ceiling.  I am planning on running 16' strips of 12v RGB 5050 (150 LED) up each rafter.  So in total I will end up with around 40 strips.  Each strip is listed to consume ~36w.  Tons of info on the net about controlling and powering 2-4 strips at a time. But 40?  I'm having trouble drawing out how to power the strips (power supplies + amplifiers) at the same time being able to control them from a single controller.  (A simple generic controller that has selectable colors/ blinking/ etc)  Is is possible to control all these with a single RGB controller? I would love to get into a DMX setup. But all the DMX controllers I've seen only show controlling a grid of 300 LED's.  Is there anything remotely feasible for a home setup that could control 6000 LEDs?

BBC Magazine readers give 40 ways we still use floppies

This fun article from the BBC website showcases readers' responses to Sony ceasing production of floppy disks.  There are 40 picked responses, many of which just talk about legacy hardware that still uses them for data storage, but some of them are easily 'ible-worthy.  Highlights: 1. I regularly buy floppy disks. I own a pub with a retro theme and I use them as beer mats. 4. Not as much a user as an owner of a great many floppies, I was planning to tile the roof of my shed with them (using the two existing corner holes to take the nails) until my wife forbade it. 13. I put handles on them and sell them as spatulas. I sell thousands of them a year. 18. I've always used an old floppy disk as an ice scraper for the car, just the right combination of rigidity and flexibility. Just don't use the side with the metal sleeve on. They last about a year before they need replacing from my endless pile from the 1990s. 28. Floppy disks are ideal "floppy table" stabilisers, whether in the dining room or on the patio. They are also good for wedges filling in gaps where wood has to be cut. I have also embossed them in a cement pathway in a splendid "talked about feature" as they are of no use whatsoever for storage. Enjoy!

Inverter question? Answered

I have recently made a pond in my garden and to avoid spending lots of money in electricity, I decided that I would power it with a solar panel. My pump is 220v 34w, so I thought that a 40 or 50w solar panel should work. However, i can't find any 40-50w inverter, only about 150w. So, my question is, will a 150w inverter draw 150w from the solar panel if powering only the 34w pump? In other words, will a 40-50w solar panel be able to power a 34w pump via a 150w inverter or would I need a 150W solar panel for that?
