SAMSUNG BN44-00669A L60G1_DHS POWER SUPPLY https://www.abctay.com/original-samsung-bn4400669a-l60g1dhs-power-supply-p-289.html
Testimonial: "But the red light does come on when plugged in. Its just that the tv itself wont turn on. Shouldn't this indicate that the power supply unit is working properly?"
Red light comes on to show that there is power to the unit, when turned on the light changes when it senses current draw. Since it is not changing to show current draw, it is highly suspect that a latching circuit has failed. Unless you want to measure specific voltages and capacitors then you just replace the most likely defective unit and that would be the PSU.
Not so fast, I hate having people ordering parts they don't need because of bad advice!!!! You will need to test the PSON or PWR_ON voltage before ordering anything, that signal comes from the main board and if you don't have that then its the main not power board that has failed, Ive replaced a lot more main boards than power boards with a symptom you have...the voltage at that test point should be around 0 with the set in standby mode and go to about 3.4 when you push the power button on the TV...if you get that voltage then change the power board if you don't then its the main
Hey Larry nice of you to read my post to the end where I said " unless you want to measure specific voltages and capacitors..." So I did not give bad advice!! Also your post assumes the OP knows how to check voltages etc. and wants to troubleshoot to the component level.

SOURCE: samsung tv LE32R74BD standby light on but wont turn on
samsung tv le32r74bd had tv on standby and wont turn on,it is stuck on standby please can you solve this
The unit is shutting itself down because a problem was detected internally. When this happens, the standby light should blink a repeated pattern. Please count the number of blinks and post the number here. That will indicate the circuit in which the problem occurred.
Thanks,
Dan
