My TV details: Humax 20.1" TFT-LCD TV. Rating: AC 100-240 V, 50-60 hz. Model: LU20-TD2 (Not sure if these needed but figured I may aswell list as much info as possible, the TV is around 2 years old). Problem: When I turn the TV on, the screen flashes continuously to the point where it's pretty much like a strobe light. It's impossible to look at it for too long. I can still see the picture on the TV or the xbox, but the picture is flashing. It first happened like 2 weeks ago, at first the flashing stopped after about 2-5 minutes, it then progressed to 10-20 minutes, but now it's taking hours for the flashing to stop. Sometimes it doesn't stop flashing until turned off and on again and repeating the process. Any ideas on what to do ? Thanks.
