Tip & How-To about Televison & Video
I see a lot of bad capacitors in my daily grind and most of the time the symptoms are very similar, even across different brands. What I see most commonly are bad filter capacitors on power supplies. My customers will tell me that the set used start up fine then over time would take longer and longer to finally start, or they would have to press the power button several times before being able to watch tv. In these cases I remove the back panel and almost always see a bulged or burnt looking cap. A good rule of thumb when replacing caps is to keep the capacitance the same (1000uf or whatever your cap value is) and go up on the voltage at least 10 volts. Any bigger and the cap may not fit.
As always be careful when working on your own tv and make sure it is unplugged when you start the disassembly. Caps can hold a significant charge so avoid touching both pins while it is in circuit.
When in doubt, call a professional.
