I have a Magnavox 46'' FP4640 W104 Projection tv that i had check out cause it wasn't coming on and the repair shop says the Focus block is bad. They called around to shops that they do business with and none have the focus block and only site that they found was Here its the 16 item in the list. So my question is this focus block is suppose to replace all these models 483510097203, 483510197006, 483531057402, 483510197018, 483510197017, 483510097465, or 220490-1, 220493-1, 220493-3 , 220709-1. But they say i need model 483510097465 focus block that was in my tv and that no other will replace it but the block on the site says it replaces any of them numbers cause i have a 52" Magnavox with focus block model 220709-1 and looks exactly the same. So would it work and does any one know of any other tv part carriers they my have it cause $189.99 is kinda to much. Thanks for any help

If you are sure you want to order this part it is available here: http://www.andrewselectronics.com
Be aware that the OEM (original) is no longer available and they can supply a generic replacement only. Suitability of the generic is unknown.

The part number is 483510097465 and costs 94.67 + shipping

Thanks Jesse.
Im not sure if the site i found is OEM or Generic but that price is a big differents and i my give it a try cause the tv worked great before that except it wasnt bright. So would the focus block cause it not to get bright cause it was failing? Cause you could turn the knobs on the focus block up and you still couldnt get good brightness or get the lines on the tv screen from to much power

The age of this set says that there is are only two possibilities that will cause a dark/poor picture. You may very well have a crt coolant problem and you may very well have end of life on all CRT's.

However, complete loss of picture/sound may or may not be caused by this part. A new one, even if it brings back your picture, most likely will not correct a dark picture that is caused by bad CRT's or contaminated fluid.

Hope this helps

The picture is clear without any blurriness and fluid been changed. Its just kinda dark. The tubes can produce a bright picture when i played an army game and the flash/stun grenades go off the picture really brightens up that it hurts your eyes kinda, or can a tube still do that at end of its life It just seems like something aint giving it the default brightness.

The guy at the tv repair shop said he removed the main high voltage wire from the focus block and tv powered on but when put it in the focus block it tries to power on but shuts off.

Thanks for your help and info Jesse
