I am new to repairing TVs. I am an arcade repair man and so I'm not totally new to electronics. Difference is, I don't know where to get parts/schematics for TVs. If it were a wells-gardner k7400 25" monitor sure, no problem, but as for TVs, I just don't know. I really hate to junk this and have to buy another one. I'd like to get into TV repair. Can anyone tell me where to start? Thanks Erick rca d52w19 52in rear projection television
The typical power input involves a small line filter, fuse, inrush current limiting resistor (1.2 - 2.8 ohms) rectifier bridge, filter capacitor(s) and a 120 volt regulator. All located quite close to where the power cord connects. If there is one diode shorted in the bridge, replace all four if they are discrete. The fuse and the resistor may both be open, depending on the level of damage. Make sure the input and output of the regulator are not shorted together. Even if you get the set to come to life, the tuner may be toast, as the antenna connection and power line serve to be the entrance and exit paths for the damaging energy. Respect the high-voltage section in the TV just as you do with the monitors.
If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
