08-09-2010 | | Universal remotes will usually handle all the "basic" (power On/Off, volume up/down, channel up/down, mute, etc.). Now-a-days remotes may even let you do some of the menu driven TV commands (changing picture bright/tint/color level/contrast/shar |

08-09-2010 | | Either the speaker relay drive circuitry has a fault or the speaker relay is doing one of its jobs and NOT letting the speakers connect because a speaker would have a DC voltage applied to it due to a defective left (or right) channel fault. |

I looked over the circuit boards for obvious damage and found nothing. However, I checked all the ceramic fuses I could find and one |

09-09-2010 | STR S6307 be replaced by STR S6709 ? | are these interchangeable?
A diode test of 1.1 volts btw pin 1 and 2 => FAIL ?? right ?
I have on hand also a S6707, test pin 1 and 2 = ok
TV is Panasonic C150 chassis TC-69R62,
I don't have exact schematic, but do have something that might |

Do you mean a part number for the whole board? Are you suggesting replacing the whole board? |

09-09-2010 | | disconnect the SCR gates, then monitor the voltage at the optoisolator,
check the specs of the SCR for what gate trigger voltage they need
observe this voltage when commanded to run |
09-09-2010 | Here are the pinouts | Hi!
Here are the pinouts.
I need the schematic of the board because is missing a IC , IC 591
If someone have the schematic please uplod it.
Cheers! |

09-09-2010 | | Check for a DC voltage on any of the four contact terminals {~} (NOT coil of relay terminals{.}). Anything more than a volt, you have a problem with that channel.
