You're sitting back couch-potatoing and something goes wrong with your television. Quickly, you scour your files for the warranty receipt only to find it has lapsed. Rather than call a repair technician to charge you hundreds of dollars, you decide to try to fix it yourself. After some heavy Internet searching, you find the transformer is the culprit. So you unplug the TV, crack open the rear of the television and locate the transformer; here's what to do next.
Instructions
1. Make sure you are grounded before touching the transformer. Even with the television unplugged, enough static electricity can be present to give you an unpleasant shock and damage the transformer beyond repair. Touch an appliance or fixture to discharge any static electricity.
2. Put on gloves and unfasten the mounting screws holding the TV transformer in place. Remove it from the television and place it on an anti-static mat. Remove the assembly screws with a screwdriver and open the transformer case.
3. Inspect the inside of the transformer for corroded or frayed wires, burn marks or oxidation. If you find any frayed, corroded or oxidized wires, remove them with a soldering gun and replace them. Wipe the inside with denatured alcohol and cotton swabs to clean away corrosion.
4. Locate the capacitor. Discharge any residual static electricity from the capacitor by touching an insulated metal screwdriver. Set your multimeter to "ohms." Check for resistance by touching the probes to the capacitor. If you get infinite resistance, the capacitor is bad. Unsolder it from the transformer with a soldering gun and solder a new capacitor into its place.
5. Reassemble the transformer casing, mount it inside the television, and plug the television back in to test. If it solves the problem, turn the TV off and replace the rear access panel.
