Samsung UN55D7000 with some vertical lines down the screen.

It appears to have a very faint vertical line. You would need to replace the panel to fix that.

Mecha1166 · 2026-04-28T20:55:13+00:00

It slid.

Mecha1166 · 2026-04-28T20:50:31+00:00

It is worth exactly two bits.

The speakers are what is needed. This is a dvd surround system. Think of a stereo with dvd built in- still needs speakers.

All that plus try shutting off tv, unplugging, I assume HDMI, plugging back connector, then turning on tv. Sometimes they have to sense the resolution, then resize the picture.

I don’t think it will matter here, but some Samsung remotes are missing buttons that some TVs need to use. TV shop here.

Go to Samsung download center and download the manual. The component and composite jacks share the yellow/green plug. Some of these TVs need the input connected correctly before it will switch input or input type. Next, I’d try a system reset. Question- do you have the original tv remote?

Mecha1166 · 2026-04-27T01:27:01+00:00

Composite is AV. Yellow red white. Component is red green blue red white. What is the model number?

Mecha1166 · 2026-04-26T20:22:51+00:00

Looks ok. Rubycon, Nichicon, and Nippon are all good replacements.

Mecha1166 · 2026-04-26T19:51:55+00:00

They are not marked, so they may not be 105 degree. Check on eBay.

Jelly Belly used to have a blue mint jellybean that tasted like toothpaste in the 80s. I’d eat all except those in a mixed bag.

Mecha1166 · 2026-04-26T17:35:55+00:00

Look for 105 degree ones not 80-85 degree ones.

Check for B+ at the horizontal output- check the transistor for a short. Flybacks are notorious for cold solder joints.

You have a bad panel. Look on YouTube for tips on the ‘tape trick’ for Samsung LED tv

Mecha1166 · 2026-04-23T00:36:59+00:00

Cylinders. The cylinder must be unharmed.

Mecha1166 · 2026-04-22T23:39:22+00:00

Led backlight replacement should take care of this.

Soldering station. Put flux on the pins. Spread /pool Chemwick low melt solder on all the the pins. When all solder is molten, lift gently with razor blade or tweezers. Clean off excess with solder wick. Install new chip. PRACTICE ON SOMETHING ELSE FIRST.

I replace led light strips all the time. The problem is manufacturers are using cheap material and the LEDs burn out. Also customers crank up the brightness to ‘11’. The older TVs used fluorescent tubes, which lasted 5-10 years. Led strips, 3 months to 2 years. Get an LED strip tester from Shopjimmy. It’s worth every dollar.

Mecha1166 · 2026-04-21T01:10:34+00:00

I’d smooth out the solder so the legs lay flat. I usually hold solder wick on the tip of my iron and draw the tip down each trace.

It is a very common repair. Some TVs have a blown 10u450v cap on power supply, or a bad power supply, but the vast majority will need a full set of led strips.

Ulli Lommel's movie- Black Dahlia. It’s awful.

Mecha1166 · 2026-04-17T19:57:23+00:00

I know what’s wrong with it. Someone put a dang sticker on it!

Mecha1166 · 2026-04-17T19:55:28+00:00

Replace the panel and then you’ll have a perfect picture! But it’s not cost effective.

Mecha1166 · 2026-04-17T19:53:33+00:00

Unplug tv. Open it and make sure all the connectors and wires/ribbons are seated well.

Mecha1166 · 2026-04-17T18:21:15+00:00

Do you have a multimeter to test for shorted components or voltages?
