hello companions of me I repair, I have in my workshop a samsung slim 21 inch tv, cl21l50mq with chassis ksbh aa41 0, 111329f. I must say that I don't have much practice but try several things that I describe. When I get to my hands I tried to look for information and a scheme, I found a lot but of many similar models , until I think I found one the cl21zmq chassis ksbh not complete but try to guide me. the tv has the following integrated la42032, c2073, la7845, khb9d5n20p, tt2222, strw6753, kia7805, fb d27m-11 19c.
the tv does not appear to turn on, when pressing power the LED turns off and flashes about 5 times and starts again with a pause. I open it, I test the usual input and source voltages: in sb a voltage of 12v (where in 14V deveria), 5.4v (6.5V), 7v (12v), 109v (120v). When I press power, they appear: 12V, 5.4V, 10.4V, 117V respectively. I search the circuit and see that there are other sources of the fb and other integrated regulators. I find the one of fb +16.5 which in on da + 15v and the one of -16.5v, which measures -14.8v. I have high, I have filament on. I thank the community for some guidance which I would appreciate and try to experience. Thank you in advance.

hello manolo karval, change the integrated vertical and connect the antenna. I had the sound, I touched the screen and the video appeared. It has as a false contact in the screen setting. Thanks for the guidance, sometimes one becomes saturated and does not know how to continue, I am tested to see if the video fails but I have to see if I can get the fb to change. if you put it as a solution I value you, but the same thank you

Hello Friend. if when you touched the scren of the flayback the image came out, leave it to the test, it may be that this scren is a little loose if you hold it and dried with the image you can put silicone but if it does not improve you have to change the flayback to another one of the same number or A replacement Cheers
