Bad electrolytic capacitors in the power supply or open resistor in the power supply startup circuit. I had this problem of 220k ohm 1/8w r1 in a sharp 20"lcd. This resistor is connected to + of the main bridge through a power diode. Tim Rasch

32" HD TV question: TV developed a prolem last

More likely the main board may be damaged (can you still turning the TV on and off, volume up/down are OK?), OR the backlight INVERTER is out.
Please read my guide for more details. By the way, did you unplug it for about an hour to see if it will reset?
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

Capacitors kit: he can make you a set of caps.
Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.

Have to reset or it is reset to factory settings?

Has anyone been playing with this TV, i.e. repairing it, replacing boards etc?

I believe - do not know it for a fact - that Samsung has this protection in palce which identifies the boards in a TV and once you switch a board the TV needs to go through a service re-administration to remember its current configuration.

There's no explanation of why would a TV need to do that other than to restrict users to Samsung service centers only.

Again I do not know this for a fact, but I have seen other Samsung TVs that do exactly the same and they start doing it upon replacing boards on them. It's a simple logic.

TV worked fine one night, next day screen is white.

The LCD Panel failed. There is no easy fix but try to get the T-Con board to fix the issue. However, this part is usually only available with the whole LCD Panel. This is usually the most expensive part in the TV and the whole TV needs to be taken apart to replace the panel.

Might be economically viable if you can find a place that carrys the T-con but Dynex parts are usually hard to find. The LCD Panel part alone will exceed the cost of the TV.

Tv shuts off after 6-8 seconds

capacitors in the power supply, they all should be replaced, before it takes out the rest of the ps. there are companies that rebuild them if your tech is not up on repairing them.

Samsung clicking on and off but not coming on

The bang you heard was probably a capacitor. Since you are still hearing the TV attempt to power on, your power supply and it's fuse are likely fine, but if the capacitor was on the mainboard, the TV would require service unfortunatley.
