Question about Televison & Video
When I turn my Hitachi ultravision TV on the picture scramble for the first 2-3 min then there is no colors for about 10-15 min, till it warms up, then the picture is distored with verticak lines, any suggestions? the model # of my tv is 50UX18B/19K
Its a older set and I have fixed and even owned one---bad solder connections and or convergence problems---can you describe better what it looks like when cold?

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.
The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.
