Hi,
Vertical colored lines usually means a bad panel. At the least it might be the t-conn pcb (a board connected to the panel). You might get lucky and just unplugging and replugging the LVDS cable (its a thin computer cable with lots of wires that goes from the main board (it has the audio and video plugs on it) to the t-conn board. You usually push in the clips on each side of the connector to release it. good luck! Panels cost more than the TV did.

Tv won't come on
Either your power supply board has a cracked solder joint, or it has some faulty capacitors that need replacement, indicated by their bulging tops. Either way, the power supply needs inspection. Only do this is competent to do so, otherwise get a qualified TV engineer. Hope this helps.

Hi
Thanks for using FixYa. From what
you have described it seems that you
might have a backlight issue with this TV set. It could also be due to the
inverter circuits for the backlights. The inverter is the power
supply source for the backlights. There could also be a screen driver
problem; if it is then you have to change the entire board. All this is only
recommended if you have some kind of expertise for checking the internal
circuitry of the TV as these units have high voltages running even when the set
is switched off.
Please do accept the solution
if the issue is resolved or else revert for further assistance.
Thanks

Two problems 1) when turning on it frequently
This might be two seperate problems, But sometimes just this simple one can fix both. You power supply is bad. The caps. used in them are under rated at 10 volt and should be at 16 volt or better. They should be replaced and that should fix your problem. REPLACEING the power supply will just have the same problem happening again. If the purple dots do not go away, Can be the T-con/LCD controll board or the main PCB board. Have the power supply repaired.
If you are good at soldering? The caps that are bad,the tops of them look rounded and are NOT flat.
They also have a neg - side. Important put the neg - side where it belongs, board should be marked - or circle w/one side darker or lines in it. That is the neg side.Common bad Caps are 1000uf 10v,1500uf 10v,2200uf 10v,and 3300uf 10v. Replace the same "uf" rating but with a 16-25 volt or higher.

Samsung LN-T4665F when powered on
You more likely to need to backlight inverter boards, thpower supply should have 24vdc for the backlight inverter board, the 24vdc power supply get the trun on command from the controller board, that is what should have been checked first. So look for 24v or measure it directly on the inverter board connector pin. The invereter board also has a couple surface mounted fusesYou can get the inverter board here but make sure to match the number:
