Hisense 65p7 sound but no picture

[jake12021]

Hi all,
I have got a Hisense 65p7 tv. The red standby light is solid when plugged in. When turned on with remote the red standby light flashes 17 times and then stays off. The screen lights up the smallest amount and need to turn off with remote again to get back to a solid standby light. Ive already gone through replacing power board and main board and neither fixed the issue. The back lights under the back panel are lit up when tv is on and sound still works. Wondering if I should try to replace the t-con board? Or is there any tests for the leds? (I have a voltmeter)

can you post some clear straight on pictures of each board and one of the whole back, as to see how everything is connected.

Usually if you have sound and backlights power on the mainboard and power supply are good.

Try unplugging one side at a time of the lvds cables going from the panel to the tcon and turning on. See if you get a picture on half the tv.

Hi Jake,

I have the exact same issue with my Hisense, down to the red light flashing 17 times and no picture.

Just wondering if you have found a solution?

I was going to go ahead an order the LED light strips to see if this is the issue.
