Hi, this sound like the same fault as i had, our tv only had half the screen go off also, the right side, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps

SOURCE: ln55c650 keeps flashing bright to

I had the same issue occur on my ln55c650 (screen flickering, not the actual image but the front lights flashed which was too distracting) and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.

Picture dimmed. can see the picture and in menu increased the backlight to max but did not go back to normal. checked eco settings and did factory reset. still very dim but can see the picture.


Yah kindly follow this tip. After loosing the back cover when the tv power cord is removed from power socket, check for bulged or defect power capacitors in both the primary & secondary side of the power pack if found any kindly replace it with the actual or equivalent value as this electrolytic capacitor defects is much common for Samsung power packs

Sounds like nothing more than a tcon cable connection. I would try unplugging then plugging the cable connection to the tcon and also the two upper tcon cables that are located under the Tcons metal cover.

Samsung LN55C650 shut down; won't come back on again!


Someone has to open the set and look first at the power supply--if you are not able to do that consider having a shop look at the set.

My Samsung rs 2556 SH side-by-side fridge is making a loud whirring noise, but when I open the fridge the noise comes to a sputtering stop. It starts again a few seconds after being closed. Noise sounds...


there is a evaporator defrosting problem; ice building-up. the evap fan is mounted right on top of the evap coil. this will get progressively worse; and, the fan will get completely jammed with ice; and stop altogether. your fridge will get warm and the freezer will not cool properly. you should get it looked at asap..

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

My monitor goes dim after a few minutes. When you switch it off and on again the dsplay is ok then becomes so dark


Hello,

How dim is dim? If the picture is still visible just like half as bright then your have backlight tube problem and unit LCD needs to be replaced, not worth repair price. If the picture goes out almost to a black screen where you can just bairly see a faint image then you hold the screen just right then you have a backlight inverter issue. If the problem is the inverter then you should be able to replace a few parts and get your unit back going. If you think you can open the unit up and maybe solder a few parts then I would open the case and look for bad capacitors on the power supply board. I can send you pictures of what to look for if you are interested. We also have a repair service for those units, most power issues run $15.00 plus shipping. Let me know if you need help opening the unit and checking parts.
