This item is "junk." Overall condition is fair to good. Symptoms of the failure: ・The screen suddenly went blank. No sound either. ・Standby power is on, but the error lamp is lit (according to my research, there's a problem with the power supply box?). It's said to be a common failure, so I tried cleaning the dust off the circuit board as a last resort, but it didn't fix it. There was almost no dust inside. Therefore, I only disassembled the back cover once. Please use it for parts, etc. The LCD screen is in good condition, although there are some scratches. ※Since I don't have the original cardboard box, I will ship it in the "24V34" box shown in the first photo. Please note that the item being sent is "24S11."
