Caps have completely fat tops for sure? Check the ECR of the caps?
You will need to do the voltage checking on those DC filter caps.
Please read my guide.

How do I fix my Visio tv when the screen suddenly goes almost black and white?


Hi Evan
Essentially it's a computer inside a modern Flat Screen TV these days. Not a lot that the average person can do...
But... if you feel capable of opening the back....
Once you get inside and check for loose or poor connectors,
I would be looking for leaky Electrolytic Capacitors.
Usually in the power supply section.
Look for brown fluid leaks on PCB & a very slightly puffed out or bowed top on the cap. (ready to explode)
Take a picture of suspect. Take note of Polarity (black stripe) & write down uf & voltage & temp values.
eg 1000uF @ 25v
To prove you are on the right track, you can connect a similar rated Cap across (in parallel) the existing Cap.
Depending on space etc. Even by short extension wires.
Power up & see results. Fault Gone or Not?
Then...
Unsolder & Remove suspect Cap & try to replace with higher voltage rating & slightly higher uf capacity depending on space available around the components.

Good Luck

Power supply clicking, turning screen on and off


even though the capacitor looks ok doesn't mean such. I would suggest having the capacitors tested.

Black screen with sound


Hi,
You Tv have problem with the backlight inverter board. This type of complaint can occur under two circumstances.
1.Faulty electrolytic capacitor in the power supply board
2. The back light inverter board.

If you have knowledge in electronics then check the power supply for any faulty or budged electrolytic capacitor. Have adde the picture of faulty electrolytic capacitor how it will look like. check the link. faulty capacitor .

If the are no such faulty electrolytic capacitor then you have to replace the back light inverter board. There is no repair possible with inverter board because its spares are rarely available.

You have didn't mention any model number of your tv. so its not possible to add the exact picture of the inverter board.

Ok

Hi...

It sounds like you have an output amp failure and it looks like you paid good money for it.

If it's under warranty, find a service place. If not let me know your location and I can suggest someone to fix it

Used as second monitor suddenly stared to go dark


If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.
