Question about Samsung LTN1765 17 in. LCD HDTV
LCD can only be turned on by the power on on the front panel. Remote appears to not work. Buttons on top of LCD TV also seem to not work. No picture or sound. Is this an inverter problem? Is it worth fixing?
Have the same problem and C21 fixed my TV. I had to use a Trhu-hole capacitor 10uF/35V that I found at Radio Shack for $1.59. Its hard to find the exact SMD component but with little patience you can do the job. Thanks a lot!

I replaced the c21 with 25V 10uF and so far it is working well. Thanks all for your precious comments

Replacing the C21 (10uF/16V) works on my LTN1765.
It was MCU reset issue. The C21 and R219 (200 Ohm) set the power on delay time. The degraded C21 made the time constant too small.
Attached shows the time delay from Power-On. The IC chip (IC21) is KIA7045, voltage detector.

Buy an lcd tv since you are going to have to change to a digital signal soon and will need a converter. So it makes more sense to buy a new tv any ways. I took mine apart and only got more head aches...lol so I say if you can afford one buy a lcd tv they are going down in pricing all the time.... Sorry but thats what I am going to do....
Hope this helps but not sure if the c21 replacement will work for everyone.... I just could see spending all that time and extra money on the problem.....
might not be the answer you were looking for but like I said that was my solution.....

Well on my set every once in a while the light stops blinking and it turns on, you can even turn it off then on several times, but after its off for a few hours its back to the blinking, its not the c21 in my set it looks good, however try leaving it on blinking, and with the back of the set flat on the floor, if you ever see it not blinking turn it on and just leave it on, and when your done just switch it to pc mode so he screen saver can run saying no pc

Same problem here too..i have it apart and only thing i can figure out is it might be the inverter board, found one for about 50 bucks but im not gonna order it until i find out if that is the exact problem or not.
