Do lamps have adjustment? I have a yellow and blue rainbow effect along bottom of screen. I am pretty handy and well equipped.

This would be a convergence adjustment. Check your user menu on the tv. Look for an item under video settings for a something called "Converge" or "Convergence". See if you can adjust it enough to fix the problem. If not, you may need to access the service menu and adjust from there.

Heckler, your tv has blown parts in the convergence circuit so you need to stop pulling plugs or you will do more damage to the set. The convergence IC`s will need to be replaced and probably 1 or 2 support resistors, Then the set will have to be re-converged, the shop you talked to is correct that it`s a common problem, mine failed 8 months ago in my 53" Hitachi. $400 to do that repair is pretty pricey BUT it really depends on where you live, Major sized city`s charge big rent, taxes are higher etc. etc. so tv shops overhead is higher, I would get out the phone book and start calling all the shops in your area for price quotes. Any questions??? email me back, hope this helped, Happy Holidays BMW Rider

Double picture red and blue, not converging

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

This problem is of "CONVERGENCE". You have to replace the convergence IC's which is better to buy a new one TV, Just contact any expert and replace the convergence IC's and your TV work fine again you need not to buy a new TV.
