Try here;=>...
http://www.retrevo.com/...ual/id/275ci966/t/2/
Click on the TOP user manual (4.16 MB) , that will open a new window that has "My Manuals" on the top....
Scroll down & skip the requested email info & go to #2 & enter the captcha code, click on "Download Now" & wait for download to start...
Open manual , go to page 26 & 27...
Start with the Red convergence adjustments that I PMd you...
My bet is they won't adjust...

Let me re-phrase the question(s)....
When you try to adjust the Red convergence , can you move the line up & down ???
When you try to adjust the Red convergence , can you move the line left & right ???
When you try to adjust the Blue convergence , can you move the line up & down ???
When you try to adjust the Blue convergence , can you move the line left & right ???
PLEASE answer ALL the questions specifically....THANKS...Sly....

THANKS for the answers....

I think it's time to change the convergence ICs...
Do you know which ones they are ???
IF you have the tools & soldering ability , that would be the best & cheapest way to go...
IF you change the ICs ONLY , your convergence adjustments should be a snap when you are done...
IF you change the sub board (Costs more) as you said in your PM , you'd be asking for a big time convergence adjustment proceedure...

Your call .....


GOOD LUCK....Sly.....

OK , here ya go;.....
eBay , & seller has 100% rating...
http://www.ebay.com/...Bundle-/270758729395

He has 2 GENUINE SANYO STK392-040 ICs for $19.95 USD AND FREE Shipping (Maybe to USA only ???).....
There is a LONG list of countries he does not ship to , but I did NOT see Canada on that list....
Click on the sellers name on the right side to contact him for shipping info...
You will need a PayPal account to buy, there're free to get...
(https://www.paypal.com/)
Don't forget to get some heatsink compound for BOTH ICs...


Have a GREAT day.....Sly....
