Samsung service menu problem
Hello,
I'm wondering is someone can help with this issue. I was unfortunately going through the service menu of my Samsung TX-R2435 (to see if I could find any hint of a "wide" mode, which is advertised everywhere for this TV, which I bought used) when I hit an option that I shouldn't have touched. Actually I didn't think it was a command but an access to a sub-menu. Anyway, it was called "bus stop" and what it did is actually deactivate all controls in the TV (as well as the service menu itself). I had to unplug it to get it to turn off. Now, when I try to turn it on again, the light goes green as normal but then turns off after one second and the TV remains blank (it does "charge up"). I have tried leaving it unplugged for 4 hours but it didn't reset anything apparently. It's as if it is locked into a perpetual state of going on stand-by. Does anybody have any idea on what is happening and how to fix it. Thanks! |

Samsung service menu problem
It is possible for you to lock out the initialization of some of these sets.
The Samsung sets are normally set up with an external interface. The type depends on the models series. Take the set to an authorized Samsung dealer to have the EPROM firmware initialization re-set. -- JANA _____ LeChuck wrote in message ng.com...

If changing it would fix the problem maybe I could just go ahead and do it myself, but what are the chances of it being actually the problem? I actually did not enter the "EEPROM" submenu in the service menu. |

Samsung service menu problem
This is exactly why we warn customers about not to attempt using the Service
Only Menues on their products. I understand, you did purchase the product, do own it, therefore you have the abosolute right to destroy it in any matter you prefer. However, when you request information as to how to un-do your FUBARD and do not choose the obvious recommondation, then we are at a loss to assist any further. Order the E-Prom, hopefully it comes with the proper programming code already loaded, hopefully you do not flack it with ESD while attempting to change it. Enjoy!! "Jamie" t wrote in message ...

I''ve been a computer specialist for 12 years, have already done some electronics stuff (following how-tos), and I've setup many things including CRT projectors and the like. I'm fairly accustomed to go into service menus, and also accustomed to tweak things that should already properly work out of the factory. In this case, I'd ask how good is a "self-destroy" option in a service menu. I could already figure out the "take it to a repair shop" part without posting a request for help. I post in order to find something that I can do *myself*. I don't want to pay $100 to replace a $5 component in a TV I paid $50. |

t said: have you tried holding some buttons in while hitting the power switch? Yeah, I've tried that. No all the buttons, but I've tried holding the menu button, and I've also tried holding some buttons while pulling the TV back in. I'm going to try to do that a few more times and then I guess ask a local repair shop if it doesn't work out. Thanks. |

The service manual for the KS7A chassis is he http://www.eserviceinfo.com/download.php?fileid=15342 Unfortunately it's not very helpful. In the absence of a secret reset key sequence, I'd be attempting to reprogram the EEPROM chip (24C16) by hand using the settings in the manual, but then I have an EEPROM programmer. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

I actually did not enter the "EEPROM" submenu in the service menu. The EEPROM stores all the settings for the TV, including user settings such as the tuning voltages for the TV channels, brightness, contrast, etc. That said, I don't see a setting for "bus stop" in the service manual. In any case, I don't think you can just replace the EEPROM with a blank one, assuming that's what you had in mind. Then again, maybe the uP contains some default parameters that can bootstrap a blank EEPROM ... - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

As a technician, I find it annoying that service information is often only made available to select service agencies, and not to the wider third party service community. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
