It doesn't close the drawer (it opens and then doesn't close) and it also doesn't read the CD | Check the limit switch on the optical unit, it is usually bent. | Straighten the key | johnny busnadiego |

The device works normally with low volume, but when the volume is increased it turns off as if tsound was a short circuit in the speakers | Rear cooler locked activating protection | Replace the cooler and run for the hug!!!!! | EDVALDO |

The outlet burned out and after replacement it may burn again. | Change the capacitors c809 22x100v, c859 22x100v, c801 4.7x100v, c851 4.7x100v, c804 100x10v, c854 100x10v, c810 47x100v, c881 47x50v. also change c802 and c852 from 470p to 2200p (red, red, red). | Paulo Santos | |

Cd doesn't work, it opens the tray, but the drive tries to read it and it makes hissing noises and doesn't read it. | Resolder all components of the optical drive board. | Paulo Santos | |

TVs turn off so quickly that we have no idea wsound to look for the defect, sound are some tips. You will use 3 diodes in4148, connect the anodes to the connector that comes from the main board to the tube board pin1,2,3 and join the cathodes and connect to pin 5, ready, the TV will no longer turn off, you will see the corresponding defect on the screen. This applies to the brands: Philips, CCE, Sony. In the case of Sony, we use 1k by 1/4W resistors, we connect each one to the RGB resistors We join the 3 ends and solder them to the connection, cool, in case the TV turns off so quickly that we have no idea, as already explained wsound the defect is, this tactic will release the plot faster on the screen, generally it takes 10s to release it, we reduce it to 4s You will use an 800m 6+6 transformer, connect it to the filament, wait for the cathodes to heat up and turn on the TV. Tsound will be a way for you to access the error code and view the plot. Tsound is a way for you to view the corresponding defect on the screen or how to access the error code. ex:0 0 0 0 0 how is 0 0 0 0 0 it means that the TV is working correctly if a number appears it is a sign that the TV is defective in another stage, the error code counts from left to right ex: 9 0 0 0 0 this 9 points to the eeprom memory or it is defective or lost or even a lack of power. a 10k resistor in the case of sdam1 sdam2 connect a short circuit from one to the other and turn on the TV when it starts remove the short immediately the TV will turn on in service mode this is either without the TV's CR or the TV is not turning on alone The LED turns on and the LED indicates the error code, eg: 9 blinks correspond to an error. | Miltom eletronica micro e epron | ||

It does not turn on, the opto, ic regulator of the supply, 36v zener was changed. According to the diagram, the two capacitors, I already get voltage in the secondary, in the +b it outputs 50v. The 3.3 plus 1.8 appears but the 12v does not appear. What I have noticed is that tsound is a voltage fluctuation between 11v-15v in the primary, if you could help me I would appreciate it. | The power IC was found, a 1k resistor, the opt, and a burnt zener. | ||

Please note that it has to be exactly the same - b500 - the remote controls are oscillating a little out of frequency | Replace ceramic crystal | extremos |
