Hyundai LCD TV HLT 3010 Pictue suddenly turns black but has voice

Hi, I've a Hyundai LCD TV (HLT 3010) for 2 years plus. Recently, it has a problem. The pictue suddenly turns black but still has voice when it is powered up from off to 2 min, after that it is ok. It seems need to warm up. Between from off to 2 min period, I try to switch to other channel, after 2 or 3 sec, it turns to black again and keep the voice. I did check the power supply, the plug is firmly connected, no loose. Kindly advise what's happened and can I fix myself? Thank you very much Best Regards, Edmund

Re: Hyundai LCD TV HLT 3010 Pictue suddenly turns black...

This is quite a common problem on LCD televisions.
It is not a fault you can repair yourself unless you are a competent electronics engineer.

One of the transformers on the inverter board will be the cause as the tend to go open circuit. Being surface mounted adds to the dificulty of changing this item as well.

Hyundai hlt 3270 can't connect to my direct tv hd box

I know this is an old post but the solutions helped me just recently. My hyundai does not have a hdmi port and I was very frustrated. Luckily I had an old rca connector. The green blue and red cord with the white and red audio connector. If your hdmi box does not have this option you are sol. Call your cable company and request one. This is the only solution. Hyundai tvs are garbage. Good luck.

46in Vizio LCD HDTV distorted black picture when tv is turned on

Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

Watching dvd, great pictue and all of a sudden black out

7 Blinks is the failure of the SC/SU/SD PCB's (1 2 or 3 depending on how lucky/unlucky) you are.

Panasonic have a great warranty usually. Give them a ring, it has failed.

The flashing LED is the fault code.

Hyundai 32''LCD with No red power indicator.


I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need further assistance so that I can help you further.
