Hi the problem is that the number you quote LR... is not the manufacturers number- it is actualy a number used by CSA or UL as a safety certificate number.
Please look for another number probably starting with a letter such as "A", followed by numbers, the first 2 are the diagonal size in centimeters (for example A63 is 63 cm or if you convert to inches 25")
Get all the numbers as they tell us more such as CRT ear mounting, screen curvature...
Get all the numbers and I may be able to help.
