Re: Problem with Sony KDL-37S5500
I schortet 15v and sgnd. Now is good, the tv is back to the old problem.
When i turn on the tv with the t-con connected and without the t-con connected, the tv is the same only backlight and the green led are on.
I noticed that the tv is turning off after som time ( the backlight and the green led turn off, red led turns on.

Re: Problem with Sony KDL-37S5500
I made one more problem now.
I tached the 15v and sgnd.
Now when i turn the tv on it turns on the back light and the green led (like before my mistake) but after 5 10 seconds one relay clicks and the tv goes off.
the red led starts blinking 8 times.
turning the tv on ore off from the buton is not posible now.Leave a comment:

Re: Problem with Sony KDL-37S5500
When i receive the tv i turned it on and the picture was like on the video just more intense. I tried reseting the flat cables, hiting the cables resultet with little flickering on the panel. i tried the tv with only one flat cable connected to the t-con the pane had picture only on one side.
Than i decided to change the t-con board, i turn of the tv and order new board.
when i get the board i changed it and turned the tv on, than only the backlight turmed on and the green led for power on, no picture, no menu, no sound nothing.

Re: Problem with Sony KDL-37S5500
Diah i measured everything you suggested no changes on the 17v
i tried with other T-con and mb same 17v.
The cables are connected good i reconnected them 50 times in the last 3 days
The icture of the screen is after i changed the t-con.
First when i started the tv the picture was like on this video just more intens.
The video is not mine, i hope that is no problem.

Re: Problem with Sony KDL-37S5500
The board was connected only for taking picture, not for testing.
The led is turning on green, when i press buttons on the tv or the remote the grin led blinks while the button is pressed.Leave a comment:
