Question about Toshiba 50HX70 50" Rear Projection Television
It appears as if this problem is a regular occurance however mine is slightly different and the problem may be a little easier to pinpoint for you Electronic Wizards. My TV is 4 years old and it wasn't moved or bumped that I know of. I have a green shadow arched along the bottom of my screen. I went to the menu and tried to correct the convergence. I have 9 green crosses to line up to, 1,2,3 from left to right along the top, 4,5,6 in the middle and 7,8,9 along the bottom. I think that the green crosses must be stationary as there is no adjustment for them. I lined up numbers 1,2,4,5,6 with the blue and red crosses but I couldn't line up 3,7,8,9. The 3 green crosses in the corners are not perfectly shaped so the crosses will never line up. Also, numbers 7,8,9 are too high for the blue and red crosses to line up to. Number 8 is the worst making a bowing effect. Before I have to take it in for repairs and end up buying a new ic for it I thought that I'd ask if this could be an alignment problem with the green tube and if there was a reasonnably easy way to realign it? Thanks in advance for your replies.
Dont move the pic tubes that will be a costly mistake the problem is still your ics replace them all you should have two check for bad solder connections
