How to know which part to order

[Fixing222]

So I replaced all parts suspected of causing a issue except the powerboard but costs have gotten high. When I type my model number in for my TV the boards are expensive.

But when I type 17IPS20 R9 which is the board I have the boards look exactly the Same except they might have one less resistor at one point on the board some one less capacitor etc.

When I look up the schematic for 17IPS20 surley there all the same.

Might this for instance work

Or this https://rover.ebay.com/rover/0/0/0?m...2F223605326085

Picture of my board attached just trying to find out what to order

you need to consider only on yours TV size not model
17IPS20 R9 are vestel and can found at many brands of TV. but should the size of the TV correct other wise your damage will be huge

Printed Black silkscreen '17IPS20' is the blank PCB number that can be used to make many PCBA's (Printed Circuit Board Assembly), you need to go by the barcode sticker number, that is the PCBA number of the power supply for your TV model.
Vetsel schematic is the master circuit that has ALL the components for making the PCB, but the PCBA for the required TV model will not have all the components as shown in the schematic installed into the board.
So why do you think you have bad power supply.

consideration on TV size only related to the back light. if the size are deferent back light are deferent too.. other supplement voltage will be same and passed

Ah ok thank you for explaining, that is very helpful and I can look for the right thing now.
I was looking for one as I have backlight when I turn on TV and sound after speaking to someone experienced somewhat they recommended a mainboard and if that didn't work it was most likely the Power supply (I ordered a T-con from what I heard about this issue and pretty cheap but wasnt that) as I also have 13/14 blinks
As shown here https://vimeo.com/352833830
Which indicates a issue from what I hear in communication between boards (panasonic error code). So I was told the only thing left that could be so hopefully it's causing the issue.

So the power output to the mainboard and the LEDs which are the only things that matter are highly likely to be the same and ok if the screen size is the same?
