For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic. -
Re: The ultimate circuit (or troubleshooting Plasma TV supplies
I saw it! The same flux capaciter that is used in my plasma pioneer power supply!.... if I could only get it up to 88 mph.......

Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)Need some help please with a few components on this small board so that I can troubleshoot the circuit.
The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
J2 - to DC Output
J3 is Battery cell connector
however I am struggling to identify if:
Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's.... -

Hi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.

I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story
I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap... -
I have a Samsung 60-inch plasma TV, model PN60E550D1FXZA with factory remote. When cold, the TV will turn on and operate normally. After operating for longer than 30-60 minutes, if the set is turned OFF and then back ON, it will turn back ON, but there is no picture (screen remains black). I can confirm set is ON because I can hear audio from the speakers when I operate the VOLUME UP/DOWN control on the remote. If I allow the TV to rest (cool), it will eventually turn back ON with picture restored. That may take an hour or overnight.
I have removed the back of the TV and looked...12-21-2021, 02:40 PM
