Question about Televison & Video
I have a Samsung model LNT2653H purchased Jan 2008 that suddenly no longer turns on. The red LED turns on and the blue light turns on, clicks, and then turns itself off. There is a fuse (T6.3AH-250v) but I?m assuming it is OK since I appear to be getting some power (LED and blue light). I've researched and found many issues with power supplies and bad capacitors on many Samsung models. After opening the chassis and visually inspecting the capacitors (CM851, CM861, CM860, CM858, CM856, and CB852) they all look fine with no leaking for bulging. They all appear to be 1000uf but various voltages (10v, 25v, and 35v). Should I try to replace all the capacitors, or just replace the entire board (BN44-00192A)? I?ve read that Radio Shack stocks them and they are inexpensive, so I?m thinking it is worth a shot to try and replace them. Any advice? Could it be something else? Thank you.
It's well worth replacing the capacitors, but this problem can be caused by a short on the power supply (Which is what the caps do). Most shorts that arise in power supplies are result of a shot transistor or diode and of course the electro caps. Check these while your changing the caps.
Good luck with it.

SOURCE: capacitor size
You can get any size/type capacitor from DigiKey. See this thread for the part numbers I used: http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen

Good day Sir!!
A T-con board has something to do with the problem in colors and image of the TV...
it is usually reddish,pinkish or had a double or shadow image....
Had you try to play a record movies or dvds so that we can surely determine it has something to do with the T-con board or in the other parts or in signal...please play one then tell me if it is still having the same problem..
Thank you...I will wait for your comment...
