Color splotches when I turn the tv its fine for about an hour. Then different splotches slowly take over the screen. Is it the Y Board?

Try cooking the tcon board in the oven...there are some postings on youtube that tell how to do it, if that doesn't help replace the board...Good luck!!

backlight inverter or tcon board

hmmm. sounds like the screen might be damaged. You might have to get a new one. But before you do that I would try leaving it off for a while maybe a few hours or so and see if that helps.

bad main digital board. It's the bottom board on the left, try Encompas Parts to get digital board.

Unplug,replug tv an hour later.Tv it now resetting it self back to factory setting.Tv still have the same problems.The T-CON board is dead.This board is the board sit right at the bottom center of the LCD panel screen.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON board for the replacement.

Try adjusting the Screen voltage. Easiest method I know of: remove rear cover, locate the FBT (has a large red wire running from it that attaches to the back of the tube). You will see 2 or 3 adjustment knobs on it the should be labeled if you look close (screen is normally on the bottom). Turn the TV to a black screen (often an empty input works well). Slowly adjust the screen voltage knob (small screwdriver required) Clockwise, until you see some beam trace lines on the screen. Now, begin slowly turning it Counter Clockwise until the lines are gone and the screen just turns black again. Press the menu button and use the on screen menu and the top knob(s) on the FBT to fine tune the focus. Leave the cover off for the moment and see if your color is better. Repeat the adjustment if needed. If this does not help your situation, you may have something else going on... let me know.

Good Day;
It is very common for this model from what you spoke. If you handy return to me, Big Irish, and I will continue to help you.

99.9 % of the time of what you stated it sounds like a shorted CRT, picture tube. I have seen hundreds.
First, call the manufacture and complain about your concern and ask them for a CONCESSION because your tube has gone out.
2.If that does not work ; call a factory authorized service dealer to confirm problem and get an estimate, then return ti #1.
Good Luck, Day, Big Irish. I hope I helped.

The probelm is caused by either a bad color wheel sensor, color wheel or formatter board. I have the new redesigned sensor assembly and color wheels that I can sell. It is best if you send me the projector for proper diagnosis.

Since this happens after the set warms up, I would check for bad solder connections or capacitors on the convergence board. If the problem was not readily apparent, then I would consider replacing the board, as I believe the replacement board has been upgraded from the original.
