jvc hd z56rx5 dark patches
I have a JVC HD Z56RX5 reverse projection TV which has been brilliant until the last few months when a dark patch has appeared on the bottom left quadrant of the screen covering about 25%.
It is possible to see through the dark patch but not clearly.
I have just replaced the bulb after 2 years useage but the dark patch is still there.
Can anyone give me any advice on what the cause may be.
Thanks in advance.
