Replace the fan. Check the fan speed regulator circuit too. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/ If the fan has gone to its efficiency, this kind of fault can occur.

it is most likely your power supply one of the capacitors or the fuse inside the set that needs replacing

hi this could be a blown fuse inside the tv ,there is may a glass type you need to take the back off if it's black in colour then it's blown but beware if it blows again when you replace it then you have a dead short somewhere

1. Turn off the TV
2. Press "info" then "Menu" then "mute" and then "Power" on your remote (As fast as possible).

The TV will now start up in Service Mode

The place to begin would be to look at the power board:Here is some general information--:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

• No video, Power light is on or blinking.
• TV is making a clicking noise.
• TV takes a while to come on
• Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.



Capacitor being replaced! Fairly easy DIY fix.

Issue with Main Control Panel White Balance Control Board Fail to response due To Over Heat Check Regulator, sort diode, Capacitor signal... Refer to Prefessional Repair Also Plasma TV produce lot of heat.. most of then need a extra fan to prevent over heat .

Hello,
you have to open the back cover of the televiion to check for dry soldering, bulged capacitors, if fond resolder and replace bulged capacitors respectively, if otherwise Power supply board not yet die.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hope this helps....

It seems new TV.

But that kind of problem is related LCD panel.
If you can replace LCD inverter first.
then not working need to replce LCD panel.

This is how I approach this problem: I check for menu appearing on the screen: If it has menu, I look at connections. If it does not have menu then I check voltages from the power supply. I check for the following voltages. VSCAN, VS, VE, VSET and VA. If only one voltage is there, then, the PCB that needs to be replaced is normally the SMPS and/or the Logic. If all the voltages are there, the Digital PCB should be replaced. If it is missing one voltage, I disconnect the Y Main and X Main from the power supply and check if the voltage reappears. This symptom is normally caused by one of these two boards having a short on the missing voltage line. The defective PCB and/or the Power Supply (SMPS) need to be replaced. If you are in need of a technician, contact Samsung at: 1-800-SAMSUNG If you have any other questions, reply to this post and I will respond.

1. Use another tv to check your cable make sure signal is there,
2. If signal is ok, go to Menu --> Channel --> Auto programming,
3. If still can not get any program, replace the Main board of your tv.

bro you should take it to the repairer,No other options you have. it can't be fixed by doing anything accept changing it's screen or repairing it, if it's possible

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.

It sounds like you might be dealing with backlight bleeding or an issue with the LED backlighting in your TV. This can sometimes occur over time due to normal wear and tear or manufacturing defects. If it started as a faint single brighter section and has now expanded to four, it's likely a hardware issue. While it may not be an easy fix, contacting the manufacturer's customer support or a professional technician would be a good next step to diagnose and possibly repair the problem. If you'd like, you can share the pictures for a more accurate assessment.

All I can advise is to take it to an authorised Samsung repair shop. A list is available on the Samsung web site.
