Dynex LCD TV has sounds but no picture.

[white1991]

Has sounds, back light is lit, but no pictures.

It's a Dynex DX 40L261a12.

The screen just went out.
I put the T.V in a pitch black room and flash a bright light on it at different angles and I cannot see any faint pictures.


Searched online for what could be the problem(s):
Bad inverter (I dunno how to identify a faulty one)
Bad capacitors(I see no bad capacitors on any boards)
Bad T-con (I don't see any T-cons in my T.V)

Anything else?

I'm tempting to buy a new back light inverter, but I don't (and can't) waste cash, plus I'm having trouble taking it out.

I'll post pictures once my phone is charge, if anyone wants to take a look.


Thank you in advance.

Re: Dynex LCD TV has sounds but no picture.

After doing more research, it might be the T-con?

I don't see one in the t.v.
I uploaded 3 pictures.

Model number is DX 40L261A12

It has integrated T-CON on the LCD panel assembly, nut we can still check for the DCV on them main board to see if the main board is sending the DC to the panel or not but we need better pictures of the main board, especially around the LVDS connector that goes to the LCD panel.

Also you said It has integrated T-CON on the LCD panel assembly



Could these be it?

Re: Dynex LCD TV has sounds but no picture.

That is the IR Remote sensor board.
I need MUCH BETTER pictures around that connector on the main board that goes to the LCD panel, it must be clear enough for me to trace out the connections.
