In the morning, I will pick up a Konka plasma TV, model PD32ES33. The customer said: "This TV may be re-emerging. It must be turned on for more than two hours before it starts up, and images and sounds appear. Sometimes the back cover can be activated by blowing the hair dryer for a while." The current customer is very special!
Turn the TV on and the indicator light is green, indicating that the motherboard has a power-on signal command. The TV screen is not displayed, according to the customer's situation, this boot delay starts, indicating that the power board has a problem. After the customer negotiated the price, the customer left the TV and left.
After removing the back cover, carefully observe the components of the power board and find that there are two capacitors on the power board. Immediately remove the board and replace it with 2200UF/35V two capacitors of the same model. After powering up the test machine, the TV immediately appeared blue screen.
