20 Most Recent Samsung LE32R74BDX 32 in. HD-Ready LCD Television Questions & Answers

It most likley is the power supply on the TV itself. There are 4 capasitors that are known to go out. You can tell this by the tops popping out or black goo coming out. You can buy everything you need at Radio Shack. I spent 22$ for soldering iron and everything I needed. I have posted pictures here. I also watched some videos on desoldering and soldering on a circuit board - very helpful.

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!

The problem is called pixel retaining, you need to replaced the LCD panel, no way to fix it.

Unplug TV, take off the back. One each board there will be capacitors. the tops are flat unless one has blown then it is bubbled up. If you find one that is bad, copy the number and search the internet for a replacement. Unsolder and remove the old one ( there is a line drawn on the negative leg, mark the neg side on the motherboard so you can replace the new one the same way). Now solder the new one back onto the board. This worked for my TV, hope it helps

Unpluging the set for about fifteen minutes or to see if that helps, if that doesn't do it, then it is your power supply board.

Jan 2016 --- Panzo's solution worked a treat, just remember to go into analogue, press buttons quickly, navigate to reset (option#12) and press left arrow which will remove the snow effect in analogue. Thank you, and the rescanning worked without a hitch. Whew thanks again

You'll need to go into service mode and do a factory reset.
To enter service mode you'll need to press these buttons on your remote in the following order:-
Standby-info-menu-mute-standby.You'll need to do it fairly quickly and be patient it doesn't always go into it first time,don't press and hold the buttons.
The service menu should appear on the screen.Use the up /down cursor to scan down to option number 12 (factory reset)and then press the right cursor wait will appear on the screen and the set will go to standby(don't worry this is normal)
Reboot the set and retune and all should be well

When the screen flickers on and off it usually comes from the power supply or backlight inverter being bad. For your TV, the backlight inverter and power supply unit are combined. As you can see in the picture attached it's the white part on the right side that has gone bad. You will need to replace that board. LN40B550K1F Samsung LCD TV Repair Guide

Check for swollen capacitors on the power supply board.Very common problem on samsung lcd tv's.

remove the rear panel and the lit area with clean dry cloth

I had the same problem. Had to connect using the composite cable, when to settings, changed it to HDMI. This turn the display on my TV off again. Then plug in the HDMI and it worked!

I also expected it to be plug and play... Hope this works for you...

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
