Re: insignia ns-lcd19
OK, at this point we should be looking at the main board (the power supply is OK).
I can see a couple voltage regulator ICs (3-pin device with big tab on top side).
Please take the reading with the TV powered up.
Looking at the regulator with the Big tab up and the 3 pins down.
Make the left pin as pin1, middle pin (which is also connected to the big tab internally) as pin2, right pin is pin 3.
Report the reading in the format as shown in the the link to how to test voltage regulator under my signature.Never stop learning

Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.
The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV... -
The board is daox8cmb6eo and i can't find no boardview or schematics on the forum or anywhere...
So i plug in the charger, amber light starts blinking ,there is 3.3V and 5V present, and 2.4V on the power button,board doesn't turn on, no shorts...
I've tried flashing the bios...
interesting thing is the battery was around 7,8V, and it's 11.1V battery, the mosfet near the battery is open, but not charging,i desoldered it,tested it and it's fine ,but the amber light kept going on the charger so i charged the battery with power supply and got it to about 10.5V... -
Hello Everyone!
I would like to know the Jumper location for the 2 Amber 7 White Led Blink Code error. According to Dell 2,7 Led codes are for display or the Display cable failure. I didn't changed the display nor the cable. The issue happens only when restarting the machine from windows and from the BIOS. And when opening and closing the lid the display turns off and never turns back on. But the machine is working! I confirmed it by pressing the CAPS Lock key. Does anybody has this issue and fixed it by jumpering some fet near the display connector on the motherboard. If So Please Help... -
Customer came in with shorted USB C chips, replaced and the chips are now responding beautifully HOWEVER, I am only getting 5Volts .25 amps (sometimes .243 amps) I see that the T2 chip is turning on, but I am not seeing any voltage at the SSD rails for example,
PP5VG3S_EN is not present which would somewhat indicate a PMIC U7800 issue, but I checked the voltage on the PMIC and that is present and not shorted. I tested for PP5V_G3S and those rails are not present.
ISL9240HI is present, I am also getting 12.30 volts at PPBUS_G3H so no shorts there. Both CD3217 chips were successfully...
