I have a TCL Roku 43" tv that has no picture or sound with vertical lines. I have replaced the main board which solved the no standby voltage problem. I have checked all the voltages on the T-Con board and they are ok. I suspect the VGH voltage is not present on the 2 panel boards but i can not find any marking where this voltage is identified. I am attempting to trace the VGH voltage thru the ribbon cables but need the pinout.05-06-2025, 01:40 PM

Hi,
Does anyone has a datasheet specifically for TPS65988CE that would be great.
I have TPS65988 datasheet which is for a different pinout and is not useful.

Hi guys does anyone have an info on this part? It's a buck controller
NB691GG-Z
I tried looking for a datasheet but to no avail
Thanks

Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.
I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models. I have the 40-40pin cable that was used for the models with touch but do not need touch capability, was just looking for a better quality screen and higher refresh to actually...10-02-2024, 04:54 PM -
Hi, pulled this component, (I'm assuming it's a MosFET) from an LED COB video light. Im trying to find the datasheet so I can find an equivalent replacement but no luck. Any assistance with the datasheet would be appreciated.
Failing that, a way to pick a suitable replacement component? If it's indeed a switching fet, I'm assuming I might need to measure the switching clock frequency and find a component that meets the power capacity?
Its a pair of them driving a 130w Light. Takes in 19volts. I can borrow a scope to measure the switching freq....
