Question about Samsung Televison & Video

1 Answer

Samsung UN55ES6100, replaced LEDs. Fixed no pic on right but it now has a red tint on the right side and depending on the image different image problems seem to occur. The old LED, right side had a blown LED. Looked like it arced or took a high voltage hit. I now also hear a high pitched squeal coming from the power supply board. All the caps look good. Nothing looks blown or cooked. Can a bad power supply board also cause funny image issues on just one side of the screen?

SOURCE: power light comes on - but NO IMAGE.. Power supply / inverter???

At first my tv would work for about 8 hours, then the backlight and audio would die. The light stays green like it is on. now it will work for an hour before it does it. I'm guessing it is the related to this problem. On the viewsonic store they have the PSU board, However it is out of stock. If you can get them to send you the part It is an extremely easy fix. As soon as I find a power supply I'm going to see if works.

SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

SOURCE: Samsung LN-T2632H won't turn on.

Follow these steps to figure out what problem is.
When you turn on TV, look at the back and see if the back light on. If it is on, the power supply and inverter work fine. The suspection now is main board and T-con board (the small board on the middle-top of the panel)
To find the problem from the main board or not. Look at the power supply and measure Vs on - turn on the TV, this approx 5 vlt DC needs constant once you turn on the TV. If it is drop or unstable - main board problem - replace it.
If Vs on is good - disconnect the T-con cable from the power sup. If power sup stop clicking - T-con need replacing. Hope it help.

I have a Samsung 55" LED TV (un55es6100) and the red color is flaring up. Green/Blue are perfectly normal. All other tv functions are normal. Can someone please help me figure out what to replace?

Are you using component cables or HDMI? If component, make sure your red, green and blue are pushed in all the way. Too, make sure your red audio is not the red video. If hdmi is used try a new one. If these do not help unplug your t.v for 10-20 seconds and plug it back in. All else fails reset your t.v to default factory settings.
Good luck!

Red tint right side mitsubishi hc7900dw

first try doing a factory reset through the menu. if it persists and the tint has a relatively hard edge to it, you may have a broken light tunnel and it's casting a bit of a shadow on the image. you might need to bring it in for repair, especially if it's under warranty

Green tinted people

The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,

Colors bleeding, red tint around images

The liquid coolant between the guns and the lenses may be fogged, low, or both. If the red gun has fogged coolant, you'll see red fringing around objects. It can be drained and refilled with new coolant, but it's gotta be the right stuff. You may be able to get some from a junk set, as I have done with success. Shine a light into the front of each lens. If the liquid has gone bad, you'll be able to see it.
