| LG | 42LC4R | TV doesn't turn on | TV without 5v power supply - open 2r2 metal film resistor (r508) at the power supply. It is located between the 2 large capacitors of the primary power supply. If after changing the resistor the power supply is "buzzing", that is, making a noise in the 5v power supply transformer, replace the 3v6 zener (zd501) which becomes shorted. I hope I helped. | It's also good to replace the c210 (1500mf/35v) that replaces. | Gerson Digitecnica |

| RECEPTOR ELSYS | 2.0 PRETO | Plug in, LED lights up, power key, CC appears on the display. doesn't work. | After breaking the cuca a lot, q103 appears (3bw short) | In its place, put bc556, or 557. We put 557, it worked. You have to know how to call. see dataxhite to find out base, collector, nothing to call by direction. If not, it won't be resolved. run for a hug. | Marcos/ Confresa/ MT <small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small> |
