Re: insignia ns-l32q-10a wont turn on

could the t-con board or inverter board cause this?

Re: insignia ns-l32q-10a wont turn on

You can disconnect the cable between the Main and the T-CON and see if the you can turn TV on and off and will get the backlights. You can still have possibility with bad used main board, hopefully you get the correct board that matched the original.
You will also need to look at the main signals: PS_ON, BL_ON to see if they are present when TV is turned on.

i disconnected the cable and all i get is the red standby led still wont turn on. i got the 715g33269-1 main board i ordered the same number board it is identical but at the top of the new board it where the t-con board connects it has another place for a cable to hook up (the original has the spot for it but the connecter is not actually on the board like the new one)

Re: insignia ns-l32q-10a wont turn on

Did you use the numbers as printed on the badcode (for PCB sssembly, blank board stuffed with parts) or the numbers (white numbers) as printed on the circuit board (which is the PCB number for blank board)? The one on the barcode is the PCB assembly (blank PCB stuffed with parts for particular PCB assembly), the black board can be stuffed with a bunch of parts to make a bunch of different PCB assembly for the TV model as needed. That is why the connector is not in the same location as the original.

Re: insignia ns-l32q-10a wont turn on

the white numbers everything else looks the same the new one just has another connector beside the t-con board connector i did notice there is a barcode in middle of the board and the numbers are the same except for the orig. is v2.05 and the new is v2.07 there is also a barcode next to the white numbers and they do not match at all

As you can see from SJ site: the warning about the P/N.
"Partial part number (TQ9CBZK019) is found on barcode sticker."
"Partial part number (TQ8CBZK027) is found on barcode sticker."
There are more than one versions of this model:

So I cannot tell what you have.

Re: insignia ns-l32q-10a wont turn on

the orig is tq8cb zk027 top:a mb:a v2.05
the new is tq8cb zk034 top:a mb:a v2.07


with the numbers not the same and it being a different v would that make it not work or are the compatible with each other?

Re: insignia ns-l32q-10a wont turn on

I cannot tell unless you have the diagram of the board to see why they are not the same.
So you have PCB assembly "tq8cb zk027 top:a mb:a v2.05", you may be able to use PCB assembly tq8cb zk027 version2.06... 10 or what ever.
But the new board does not have the same base number, you have PCB assembly "tq8cb zk034" version V2.07.
They make more than one assemblies for reason, if they are not needed they will not be making them since it costs money to keep track and stocking bunch of assemblies.

Re: insignia ns-l32q-10a wont turn on

thanks i think i will get a board like the original and give it a try. if it still does the same what would the next step be?

Re: insignia ns-l32q-10a wont turn on

Just have to put in the right board fisrt, BTW, was this TV worked on by someone else before and did it just quit by itself?
Make sure the new board is warranty, you cannot never trust Ebay seller, they always say tested working board which means they must have lots of TVs to put the boards in and test ALL the functions which almost impossible to do.

Re: insignia ns-l32q-10a wont turn on

no it was given to me by my grandma she said she thinks lighting hit it but there are no obvious burn marks on or under any of the 4 boards it would do nothing not even the standby light replaced the main and got the standby light( Solid red) when hit the power button nothing soild red light stays on

Re: insignia ns-l32q-10a wont turn on

Lighting surge can damage lots of component, especially the HDMI IC for the HDMI ports which most TV uses to connect to the cable box.
32" Insignia is not worth very much, so I hope you do not put too much money into it unless you want to use it as learning experience.
