Closed horizontal | I replaced the c 610 and it started working normally again, the interesting thing is that I had two more, but 20 inch ones that didn't turn on, I mean they kept the red light on the front blinking, same model, I went to test the same capacitor, and the defect was also him. | bf.colatino | |

This LCD arrived at the workshop not turning on. | Check all power supplys ok, but the panel LED blinks 7 times | I checked the manual which says it is the temperature of the bal plate, I went to check the heating of the ci's, I found out that the regs on the right side of the processor were heating up a lot, I followed their output and checked that they were feeding the ci sii9287bcnu which was also heating up, I removed said ci from the pci and the TV worked!! | BF.COLATNO |

KV-5159B

This TV works normally but the power supply is low causing a difference in width where it would have to be 115v it has 100v hence the problem, I have already changed the capacitors (c410,c411,c622,c623,c624,c626,c603,c613,c614 of the power supply and nothing. | Resolved r605 2r2 changed replaced and the TV started working normally again. | BF.COLATINO | |

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 | |

TVs turn off so quickly that we have no idea where to look for the defect, here 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 where 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. There will be a way for you to access the error code and view the plot. There 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 | ||
