Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I want to know if I could hook up a solar panels to this boost converter would I have any issues doing and I would have issues what would they be

The LM358 LM358S-13 consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM358 series can be directly...10-07-2024, 04:12 AM -
I have been pondering this question for a while but now I have see if this doable but I need to answer this question once and for all
I would like to know how to safely do this undertaking my first thought is to solder wires to the main filtering capacitors and see
what voltage I am getting and seeing if I can build a battery pack with voltage or not and if
I can find a BMS balancing protection board at this voltage level and weather or not do I have use more than one BMS balancing protection board... -
Hello everybody I try to fix thi power supply, I have voltage in bridge rectifier, and also in the large capacitor , so I thought the problem was in the pfc but then I found all mosfet ok(tested out of the circuit so I just moved on in the low voltage and here I found a short of one of the diode rectifier. I'll replaced it already but it's completely dead, I mean any stanby voltage and the other voltage is not present. I don't have oscilloscope to understand if the chip work how can I test it? Thank you for the help 🙏
