I got a customer's EPSON WF-7710 with a faulty power supply. The controller IC (SOP 8) has markings on it "6018019 8A95".
Any clew?

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 have seen some board on eBay and Aliexpress but I have not seen any for SMPS switching power board modules I would like to build one if I can not find one that is already made
Dose anymore known if there is such a module and where would I find some
While searching this topic on google I found this

I have read through this I have some switching... -
Hello!
i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.
Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

The RT8205L RT8205M is a dual step-down, switch mode power supply controller generating logic-supply voltages in battery powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and also features fixed 5V/3.3V linear regulators. Each linear regulator provides up to 100mA output current with automatic linear regulator bootstrapping to the PWM outputs. An optional external charge pump can be monitored through SECFB (RT8205M). The RT8205L/M includes on-board power up sequencing, a power good output, internal soft-start, and internal soft-discharge output...10-23-2024, 03:58 AM

The RT8205A RT8205B RT8205C dual step-down, switch-mode power supply controller generates logic-supply voltages in battery-powered systems. The RT8205A/B/C includes two pulse-width modulation (PWM) controllers fixed at 5V/3.3V or adjustable from 2V to 5.5V. An alternative LGATE1 output LG1_CP can be used for external charge pump (RT8205B). And an optional external charge pump can be monitored through SECFB (RT8205C). This device also features 2 linear regulators providing fixed 5V and 3.3V outputs. The linear regulator each provides up to 70mA output current with automatic linear-regulator bootstrapping...10-23-2024, 03:37 AM
