Question about Samsung Standard (CRT) Televisions
The top 1" of the screen has gone black. Who do I turn to for service in Boise, Idaho? What parts are required? Who will provide them? Costs?
The problem I was having was that the vertical deflection was
collapsing on itself from the top. I'm a tech and I am visiting web
sites who experience similar problems with the Magnavox 20 MT4405 in
hopes of saving them time and money."Starsong" has the right answer.
Replace electrolytic capacitor #2465. It is a
10 microfarad electrolytic capacitor rated at 160 volts. Although the existing capacitor appeared good,in circuit and out, the charge-discharge time was flat as compared with a new capacitor. Plus, when the capacitor is in circuit with full voltage applied, the capacitor leaks too much. The cost of the capacitor should be under $2. It should take under a half an hour to replace. Be certain to let your set rest, unplugged, for at least a half hour before attempting to replace this capacitor. There are high voltage present around the crt even after the set is turned off. The high voltages can cause serious bodily harm. I would suggest a tech discharge the anode on the crt with a high voltage probe passing through a volt meter and running to ground. You will need a soldering iron, solder ******, solder, and I like to use a little flux for good adhesion of component to board.
