Panasonic LCD TV, DC 12V, power consumption 15W, DI model. - Brand: Panasonic - Power supply: DC 12V - Power consumption: 15W - Model number: DI model - External connections: Compatible devices available Thank you for viewing. While I don't think there are any noticeable stains, the included black remote control doesn't work well. It doesn't respond well to channel switching, BS, or terrestrial channels. Sometimes it only responds if you press and hold the power button. The gray remote control can also be used, but it does not support BS. If you only watch terrestrial broadcasts, there is no problem with this gray remote control. It is unknown whether this remote control is for this TV. Please understand the above before purchasing.
