Samsung Le32r71b no picture

[xalien]

Hello I have a Samsung L32R71B that has no picture when it is turned on. When the TV is connected to SCART i can hear sound, backlight is also working, the remote control is also functioning. Pretty much everything is working there is just no picture at all. When i press the menu button on the remote nothing is showing on the tv. I have checked the power board and so far i haven't found the problem there. The inverter must be working since there is a working backlight. Does anyone knows what should i check? Has anyone encountered such a problem? I think that the problem might be coming from the main board somewhere, but i don't know what to check. If anyone had such a problem please share your thoughts. Need some hints what to do next with it. Thank you

We need the pictures of the whole backside of the TV so we can see all the boards, it may be the T-CON is not getting the switched DCV from the main board, or blown SMD fuse on the T-CON board.

What resistance do you read between the output pin and GND? Need to find out if the IC is bad or the output is being loaded down or oscillating due to bad filter caps.
Does it get very warm?
Do you get 1.25VDC measured between the ADJ pin and the output pin? It should have 1.25V because of the internal 1.25Vref.
