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

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.
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.

know this isn't what you want to hear, but the problem you've
described can't be fixed with troubleshooting.
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
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
or small part. If the problem is more than one of the circuit boards,
the price of repair could go much higher.
