Check whether the product is turned on. Try another channel. The problem may be with the broadcast. Is the power cord inserted into wall power outlet? Check your antenna direction and/or location. Test the wall power outlet, plug another product's power cord into the outlet where the product's power cord was plugged in. If these tips don't work, you can also try to power cycle the TV. Turn the TV off and unplug it for about a minute. Plug it back in and power it back on to reset the settings back to factory default.
Hi, The Lamp light of the TV blinks when the Lamp of the TV requires replacement. The model # of the user replaceable lamp block is XL-2200. You can download the manual of the TV by clicking here. Refer to page # 76 of the manual for further information. Follow the steps below to perform a power reset first: Try the following steps to check if the issue can be resolved. Turn off the television. Unplug the television power cord from the electrical outlet. Let the television remain without power for 60 seconds. Plug the power cord back into the electrical outlet. If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television. If the issue continues to occur, service may be required.
TVs today are becoming similar to computers and use hardware and software to deliver the picture and the sound. Similar to how a computer can lock-up and then you have to re-boot, TVs sometimes have problems that you can fix by resetting, or rebooting, them. To reset your TV, unplug the power cord from the wall outlet, power strip, etc. Keep your TV unplugged for about 5 minutes. Then, plug the TV back in, turn the TV on, and see if the problem is fixed. If the problem remains, then please contact RCA Customer Support using the Support link in the top navigation on this page.
Please remove the power cord of the TV, if it is connected to any power surge box and connect it directly to wall jack or wall outlet. Do not place any magnetic items nearby the TV. Do not completely cover the LCD with plastic cover or cloth.
The noise is coming from one of the plasma driver boards. There are 2 inside the set. These are essentially power supplies for the plasma itself and contain many capacitors. The noise you hear is some oscillation inside a cap or two. This is an indication that one or more components have drifted from their rated value. While the set will continue to work for a while, that board should be replaced. If the board fails, 1/2 of the picture will be blank or the set will not start at all. Call around to get the cost of that board. Please note that continued use of the set WILL NOT cause any harm. This is an annoyance only at this point.
just to be sure, plug something else into the same wall socket to make sure you have power there. If you have power at the wall and the TV has a detachable power cord, try the TV power cord in your computer to see if it works. Otherwise you probably have a faulty power supply in the TV.
This is going to sound pretty elementary, but my guess is that the power cord is defective. That TV model is relatively new (I have a similar one, bought about 8 months ago) and presumably is still under warranty.
I would have the power cord replaced by a repair shop.
