20 Most Recent Samsung UN55C7000 55 in. TV Questions & Answers

I had the same problem with my 55 inch Samsung TV (blinking red standby light and a clicking sound when the TV was turned on, TV would not come on). After checking components on the power supply board I found that the five 33 ohm (orange-orange-black) resistors and changed value. Each resistor measured approximately 3.6 ohms. I replaced all five resistors. Now the TV works.

I'm sorry for the difficulties you're experiencing as the HDMI port on the TV is not working as expected. Please follow the below troubleshooting steps and check the operation.

• Please make sure that the connections are secure and proper.
• Unplug the TV from wall outlet for more than 5 minutes to perform a power resetting and check the operation.
• Check whether the HDMI input is skipped.
• Please connect a different device to the same port on the TV and check the operation.

Thanks for understanding. Please let me know the result after performing the steps.

Sometimes the HDMI needs a particular order to recognize a device. You may need to have the DVD turned on before the tv or visa versa for it to work.

Hi,problem solved.. First you will need to open the back of the TV and locate the dry joint area inside the TV, You will need to locate where Some IC at the dry joint area.

In there, they are capacitors that are la belled Vertical lines on the panel(any IC written to vertical)...

When you locate the IC, You will need to re-solder the Capacitor. But before doing that,you can test if the capacitor is still working properly by tamping and the bottom of the IC. If the bottom of the IC has a swollen end, that means IC is GOOD,But it the bottomof the IC is flat,That means IC is BAD, Needs to be replaced...

After soldering if the problem still occurs,That means a capacitor or a resistor around the vertical line area is BAD and will need to be replaced..

After doing that,wa! la!, Your done..

Please make sure you power off the TV before attempting this instruction to avoid the risk of shock...

And also if you think you can not be able to fix it your self, please contact and expert for help...Thanks..

Please clarify.

I have a new one and it was warped when I received it.

Hello tony, Mostly all LCD tvs are autovolt, you can find the specs at the back. coming from Samsung, its Autovolt already.

Sounds like a power board issue. Unfortunately this is a common problem in flat screen TVs. Typicality this happens after the tv is three years old or older. Some will last several years. The repair is almost cost prohibitive. The replacement board if you sent it out to a repair shop would cost approximately $190.00 and altleast two hours labor $180.00 for the repair. Most repair shops also charge for a diagnostic fee. That fee most likely would be around $50.00.

Those 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 section 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. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty.

If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
