Samsung TV With Flickering Backlight Repaired
Sometimes we find used and defect devices that are thrown away as garbage by their previous owner. And we are lucky when these devices afterwards are easily fixable.
This Samsung UE32EH5000WXXN tv was such a device I picked up on my route back to home. These sets do not weigh much, and I kept the back of the tv on top of the steer of my bicycle to avoid any damage to the LCD screen and ride home. Nice thing of these newer model televisions compared to the Samsung sets made around the year 2008 is that they also only need a fraction of the power to fully operate. Because earlier Samsung models like the LE32A430T1 used as much as 180Watt! And this newer UE32EH5000WXXN only needs 60Watt at maximum! Which thanks to the very economical led backlight also makes these tv’s much lighter than the previous ccfl tv models.
First photo showed all boards, and second photo showed the TV label on the back of this Samsung tv.
The problem with this 32 inch tv was the flickering led backlight. And the likely culprit , an ecap 47uF/200V, was immediately clear on the power board after the backcover was removed and all boards were visible.
Next photo shows the solder side with the position of the bad 47uF 200V ecap marked with red circle.
After a new 47uF 200V capacitor was placed the Samsung backlight tv problem was fixed.
Last photo shows the now completely fixed and as new working television.
Although fixing modern CCFL/LED LCD televisions is not my cup of tea, this was another surprisingly easy fix at almost no cost!

A photo of the bicycle haul of the TV would be interesting.

In front of my steer axle a wooden mdf plate is mounted that holds a closeable postbag with 3 inside wooden side plates and one bottom plate. It in a way extends my steer and helps to carry a light large object without blocking my steerhandles. With one hand I hold the steer and with my other hand keep the object on top of the steer. At the back also two other postbags are mounted in kind of the same way with also in the bag inside shifted in mdf sideplates with extra bottom plate. This way any collision with the bags easily keeps any damage limited because of the movable inside sideplates. I couldn't find any matching picture to show how it looks.

I tend to replace most all secondary capacitors if one is gone.

You can do that but it is not necessary if ESR and capacity are still okay. Besides...opening the TV is easy if in future e-caps get bad and need replacing. This already 10 years old TV probably will go bad on other parts before that. Like the leds in the backlight or something else.
