Check the Blue CRT drive board for defective solder joints especially at the CRT socket

Ok first of all unless you know how to use a multi meter give it up and take it to a shop

otherwise start testing voltages with a mutli mete

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.

Something is out of tolerance in the horizontal deflection circuit. You should try resoldering the horizontal output and driver transformer. If that doesnt help you will need to troubles shoot the deflection circuits. If you need a link to get a good quality service manual for your model let me know and I will post a link.

The convergences amps are found either on the neck of the CRTs, or a seperate board directly connected to that area via cabling, depending on version of chassis...accordianman

Replacing the board is much more expensive than repairing it, if the repairs can indeed be done...accordianman
