Can you easily seperate the top and bottom of the ws 65807 for moving?

I doubt it as it was never designed for that kind of input, Component works best on this set and it should have only one HD input for a box marked in the menu as DTV.

If you move the convergence too far the set will shut down.

Have you done the self check this model does have?

go here and sign up for a 7 day use ($5) and download the service manual (and schematics and pcb layouts) for your tv

Yes, There are four screws on the sides in big holes under black plastic caps, and then 3-4 screws on the front behind the speaker grill. Check to see if the rear cover will need to be removed too - I don't remember... Take the screen (Fresnel) assembly off first and then the whole top section comes right off. The top weighs the most out of all the parts.

My friend , this is technician job. If you are one well, replace capacitors in vertical and check for bad connection.

Reset the covergence to factory specs from the remote. Do it three times

go to this websight leave an e-mail with your model number and let them know you need a signal board and they should be able to help you plus there prices are very reasonable and they also offer free online tech support to their customers

I suggest to visit the website of manufacture to have both question answered . thanks

that tv set is only good enough to receive a 1080i signal at the DTV INPUT. unless you can change the output of the blue ray it will be outputting 1080p

What I usually find on sets like that is that there is a loose solder joint on the CRT board itslef. You must get to the bottom of the picture tubes, pull off the CRT board from the red CRT and examine all solder joints on that board. Chances are one or more will be cracked, and resoldering all joints on the board should clear up your problem.
