Hello colleagues: Since I did not get main for a Samsung LN32C550 that burned the microphone I am trying to replace it with an LN32C450 I have already changed the connector and I have added 4 diodes at input 2 next to IC207 and another 2 at the connector that comes from the source. Difference that I find with its similar LN32C550. This board is different from what a colleague in this forum replaces and does not have the same resistance that needs to be replaced. For full HD functions I only find 2 to the left of the LVDS connector that goes to the screen. } I would appreciate if someone can inform me about this change can be made from service mode and if necessary, what parameters to change. I have always made several changes between HD and HD without problems but here it is getting complicated., The R to change are very small There are VIDEOS of Elec. Nuñez you will know, I AM SEEING ALL THE PROFESSIONAL VIDEOS NOW. GERARDO LOPEZ ON THE THEME ARE EXCELLENT DON'T MISS THEM. Grateful from now Greetings july gramont

Friend if you can make the change, first make the main work, then put the corresponding ldvs connector and test, sometimes you will watch video, other times you will have the dark screen, at other times you will have to look for the resistance, read this explanation and comment what you have done and what you see or what defect you have to keep helping Greetings and luck.

Hello, your report is very good, thanks. I should have seen it before I started. According to the display you use, the board is different. The easiest was the change of connector, it was very complicated for me the change of the R that I only see three, near the lvds connector and the doubt of whether or not the 4 diodes that the C550 has and not the C 450 When placing them, the screen is black and without blanking. the voltages of 12 and 5 volts are fine but this source if you disconnect from the main turns it on if the 450 volts are on the filter, it seems that there is a short film that I can't find. very difficult to follow Sdos

Friend you must first make the main work, verify its power and that it corresponds to the voltages provided by the source, when this garment you will realize because they turn on the LEDs and you will see the light that comes out of the optical audio, it is then that you must worry about the adaptation of the display, when you achieve this comment that the other is simpler, it is always possible, I have adapted main LCD TV to last generation display and vice versa, but first you have to get the main to go.

OK Thank you. I did some adaptation of main and T with and I stayed well, however, from full hd to hd the others provided that the tensions worked well, this board comes for both adaptations but there are bridges to change and there comes the problem. > The best thing is how it would be said after the main c450 works because it has the same source, it is to work as a decision in the connection of the display, as regards the lvds inputs.

you will not get anywhere because the eeprom data are different

I don't think that's the problem, others I did change the firmware or directly exchange the eeprom, Sdosd
