Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

SET TRIES TO TURN, BUT DOESN'T


The RCA P52920BL uses the PTK195 series chassis. The most common reason for the set not turning on is a shorted flyback transformer. To check this, measure the B+ when the set is plugged in - it should be around 145 volts. When you turn the set on, see if the B+ drops down at all. If the flyback is shorted, the set will try to start but the flyback draws too much current. The microprocessor senses this and immediately shuts the set back off. To confirm, unsolder the jumper wire bringing B+ to the flyback and put a 100 Watt bulb in its place. Turn the set on and if the flyback is shorted, the set will now stay on but the bulb will glow as bright as if it was plugged into the wall. If this is the case, replace the flyback. Let me know what you find and we will take it from there.

Wii console not working correctly


When you connect to the internet wirelessly and Wii Connect24 your Wii will stay connected and recieve messages, updates, etc. That is why the disk area stays blue and the amber light stays on. Sometimes this will create a power failure. Just unplug your Wii from the wall and let it rest for a few minutes and plug it back in. The problem should be solved.
