55 inch TCL black screen. What module is the problem?

Black screen on my TCL 55 inch. Common cause is the T-Con board but my 55s405teaa service model doesnt appear to have one after taking all the back panels off. Wondering what modal could be the cause of the black screen. Powers up and has sound. Did a factory reset with no help.

Yes worth repairing but not a crt problem. the crt's are powered by a high voltage transformer and sometimes it's caps that goes bad and in turn knocks out the crt's. but they are ok, it's in the high voltage line.

Hi my name is Roety,
I can help you with your issue ,
Most likey you need the convergence ICs replaced.
A repairman would charge about $350 to replace them
Voltage checks and a visual would be needed to determine exactly what is bad in your TV

You will get a white screen when you unplug the t-con from the main board. Doing so removes power to the LCD panel. Verify that all of your voltages from the power supply are correct. If they are, I'd look at the t-con board. It sounds like there is a problem with the t-con that is pulling down the main board.

TCL model L40S4690E. Why does TCL logo appear on screen and nothing else happens?

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

The T CON board or the LCD panel is faulty. In almost all the 32 inch tvs the TCON board is integrated to the LCD panel and is only replaceable along with the LCD panel.
