Question about Samsung Televison & Video
My tv has recently developed fine diagonal sqiggly lines across the whole screen. This is visible from closer range. When I turn my pay tv box off, the blue screen on the tv still has the same problem. Do you have any suggestions as to why this is happening, and how it can be fixed.

OK to help assist everyone having the BLUE HUE and CURVED LINES Issue
on their Rear Projection HDTV no matter their model. Here are the steps
to take. The first thing to check is the FOCUS BLOCK or G2 Focus
Transformer or CRX F-Pack. I have replaced mine, however it didn't
resolve the issue. I am onto the next item the CRT Board for Blue
(Which is the board under one of the three color lamps inside your tv)
Please see photo below (if photo is not large enough below go to link
to review notes as well) If the CRT Board is not it, then the next step
will be the Signal Board which is a larger board in the back. In a week
I will have a picture of both.
Replace the G2 Focus Block aka Focus Transformer, if Hitachi it's called a CRX F-Pack. This item will cost about $50. Not expensive. You will likely need a soldiering iron. DO TURN OFF & UNPLUG THE TV WHEN INSERTING ANY METAL OBJECTS INTO THE TV!!
FOLLOW THE PHOTOS/DIAGRAM in link below for assistance in the above instructions. I will post my next process since it was not my Focus Block that was an issue.

SOURCE: 53 inch panasonic projection tv.
check the yoke plug solder joint, as the squiggly lines in the middle usually happens if the yoke is unplugged. So check the yoke plug connections.

You need to adjust (actually bit decrease) G2 volts (calls Screen volts) of Blue gun.
If you are familiar with big TV repair and have electronics knowledge then let me know to guide you further.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
