Question about Televison & Video
There are one or more fuses inside a CRT TV which probably failed. Check those first. Make sure the connections between the control board are tight. The only other area that causes problems is sometimes the CRT tube itself. It may be difficult to find a repair technician for the older TVs.

SOURCE: tv will not power up
no reset button ,sorry. The problem you describe is pretty common with this model as its a fault in the horizontal drive circuit or in the main power supply and without the proper service manual as well as the prober tools and equipment this set its not gonna get fixed. there are no panels or user changable boards as it is a solid state set. ptscorp.com could repair this board or exchange it with a referbished board but it would still requir some adjustment that a user may not be able to handle. time to call the pro.. Sorry couldnet help ya more.. Good Luck.

SOURCE: Tv out of Focus
Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

Not likely convergence because it's simply a direct view TV. Could be vertical, a common problem with that unit is the vertical output IC Q301 and poor solder connections of the link off R305. This could be enough to put the unit in shutdown. And it could also be SMPS, possibly regulator or horizontal output transistor - you would need to test these to be sure. The HOT, if shorted, will have continuity E to B or E to C.. If you're not sure you're up to this take it to a reputable shop. What I've described above isn't too serious and a good shop can having back to running good as new in a couple of hours. One tip I might add, take to the shop yourself it will save a few bucks. Good Luck Bill
