Have you tested the backlights by removing the connector going to the main from power board, this will tell if the hot side of the power board is working and you will get backlights if they work?
You will need to unplug your TV from the power outlet and any power source for about 1 minute,then plug it back in. Check to see if the HDMI cable is properly connected.Or change it to a different socket. Do a factory reset.
This sound like an issue with the x-main board, if you unhook the power cable going from the power supply to the y-main board and you get VA and VS voltages there is about a 95% chance of the power board working ok, both the x and y main boards in this model set gave issues, one problem is going to be finding a board at a decent price, you can troubleshoot the board yourself, it's generally the mos-fet's that short, the ones that are attached to the heat sink. If you find some bad, replacement parts can be obtained from Mouser for a few bucks, they're easy to change with a soldering iron and some solder wick or sucker
This set is what's called edge lit, it has 2 led strips on the bottom of the panel, then a defusing screen spreads the light, you have some shorted LED diodes making the darker spots, new lamps should fix the TV as long as the diffuser screen is ok.
It would appear that your Samsung LN-T4665F television is experiencing a problem with discoloration. You can try a few things to get the problem fixed:
Check the connections of the cable: Check to see that the cables that connect the TV to other devices, like a Blu-ray player or cable box, are properly connected and not damaged.
Examine the power supply: Check to see that the TV is plugged in correctly and that the outlet is working properly. Check to see that the switch that controls the outlet is turned on.
Examine the settings: Check to see that the TV is not set to Sports or Game mode, which may cause the screen to appear dimmer.
Reset your TV: Wait a few minutes before reconnecting the TV to the power source. This can sometimes solve problems for a short time.
Examine the T-Con Board: The T-Con Board might be to blame if the problem persists. Discoloration issues can arise from this board, which is in charge of controlling the signal that travels between the television and the main board.
A power board will never cause a sound delay issue, if it's doing it on all channels its most likely an input issue, such as your cable box, fire stick ect
You can't use the Galaxy A32 as a remote control for any IR controlled device directly. The A32 does not have an IR blaster. All of the digital to analog tuner converter boxes that I know of only had IR remote controls. You can find IR blasters on Amazon that have a wi-fi hub that can be paired with a cell phone to control TVs and other A/V hardware. I've seen mixed reviews on these devices.
I wish that I had better news for you.
