Hi There!
I'm trying to help my friend who owns a restaurant be just bought.
He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
It's stuck using, I guess, the 2 sided tape that comes with the strip
The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth... -

Hi, I am installing a long led strip and I noticed that it frequently flickers slightly, it is not a strong nor regular thing, but it is noticeable and annoying. I have measured the voltage of the mains and it shows some fluctuations, it normally stays at around 226v, but often (every few seconds) drops down to 218/219v), and the flickering happens exactly at the same time. I have measured this at the counter and with every appliance off, so it's not related to the house electrical system, but that's how it comes from the supplier.
I know that the best solution would be to get a voltage... -
I wonder if i shorted the whole strip...where to put pos and neg to just light up a single diode...or the entire strip. The strip lit for a second...so maybe i fried it? What say you?
I have an adjustable dc power supply and was trying around 9 volts.
I have a pic of a single diode...where to put pos and neg terminals to light it up?
Pic of middle of strip..is this where i light the entire strip?
And pic of end...or does this light the entire strip?
Where to put pos and neg for single diode..multiple diodes and the entire... -
Hi, I have a Hitachi tv model L47V651, there is no image, but sound and backlights turn on, so I believe the issue is the tcon board.
I opened the tv to access the board and took the shared pictures of the T-Con board.
I saw a video from shopjimmy on how to detect the model number on tcon boards, but this doesn't have a sticker like how that video showed all boards.
I searched the P/N number and got results with the same marking name and P/N my board has but they list other specific tv models like Vizio and Philips brand but not Hitachi.
Inspecting...
