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.

Hello friends,
Looking for some guidance here. The RAM voltage circuit on this motherboard keeps burning out PU301 which is a RT8231AGQW. Copy of the board with the burnt chip attached with some voltage measurements and copy of the schematics also included.
I think I've checked almost every component in the circuit, but when I change the RT8231, the laptop starts I have 1.2V on the inductor for about 10 seconds and then the RT8231 goes south and no more voltage on the inductor. All other voltages on the laptop are good, this is the only one conking out for a reason I... -
i have Gigabyte Z490 Gaming X Motherboard .it has a power on no display fault .. no vcore voltage and debug led stuck CPU LED .
VCCIO voltage ok
VCCSA Voltage OK
VCCPLL Voltage OK
Ram Voltage ok
RamVTT OK
VPP 2.5 OK
But No Core Voltage
and i want to this vrm ic datasheet or pinout (ISL69269)
anyone have this ic pinout voltages?...06-25-2025, 07:19 AM -
I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

3+1 Voltage Regulator for IMVP-7/VR12 CPUs
Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.
Based on Intersil's Robust Ripple Regulator...11-05-2024, 03:24 PM
