Question about Televison & Video
Swollen, Bulged, Bad Capacitor The main cause of this power up problem are bad capacitors on your power if the capacitor is bad
What you need for the opening of the television is Screw driver, Soldering iron(40watts+), Desoldering braid, Soldering wire, and capacitors.
Now lets talk about the specs, capacitors hold 3 important value:
1. The capacitance measured in uF(micro farads) (ex. 2200uF), 2. Voltage (ex. 10v), 3. Temperature (ex. 105°C)
Flat panel Television power supply capacitors has 10v installed on the board and it is attached to a 12v bus which is causing to bulged.
Look at the bad capacitor and get the right information from it, remember uF, voltage and temperature. Mine, I only change 2 capacitors. It needed two 2200 uF, when I first saw my power supply it was really easy to spot the bad caps. Some Samsung LCD owners did went ahead replace all the capacitors on the power supply to make sure. Now if you’re like me, an inexperience solder, I would not recommend changing all the capacitors because to me it was time consuming for a noob(newbie) like me ^_^.
Few things to take note, always make sure you have the right polarity. Negative part is where the colored stripe on the capacitor.
But if otherwise, the power supply board is bad, you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
Hope this helpout...
