I have a 2001 Hitachi Ultravision 53" set (53 UXD I believe). My screen will go black and have no sound. Then I will get a football shaped screen sometimes with the edge colors distorted, and then the screen will come back on and work fine, until I shut it off for a time and it cools down. What would be the cause? Could I fix it? What price are we looking at here (would replacing be cheaper)?

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.

check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

underneath screen remove screws holding screen in place ,it should then slide upward and off.
