Re: Yet Another TC-P55GT30 7 Blinking Light Error

I should have them either tomorrow or Wednesday. As far as how I tested the buffer boards, either that way works or I got lucky. I do see more logic in the way you described though, as you're checking each line of output for a short.

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Thanks JeffJ. The set is running now. No getting it back from the kids once they saw it turn on. As far as the ground pads on the back of the screw holes, I used a board that was rebuilt by a local shop that specializes in audio/video components but I am not sure if they added any material to the ground pads or not. They were very familiar with the 7 blink code and stock all 3 of the related boards. I agree the picture quality is amazing. The only sets I remember looking slightly nicer, but not a better value, at the time I was shopping...

Thanks so much for the help Moreno83. I replaced the SC board after work today and the TV is back up running again. I forgot to get the updated screws from the place I bought the board so I will get them when I return my core. By the way, 5 of the 7 factory screws on the original SC board were very loose.

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Table Moreno83. I'm actually going to exchange the SC board for a rebuilt locally. Does the testing method in the video make sense to you? If I do in fact have a bad SU and/or SD board, will it cause damage to the new SC when I put it in? Again I appreciate all the help.

Re: Yet Another TC-P55GT30 7 Blinking Light Error

I got my testing method here [url]https://m.youtube.com/watch?v=MX7e9aSlbJQ[/url] for the buffer boards. Is this not an accurate way to determine if they're bad? Mine tested good with this method but the SC board tested bad. Thanks again for the help.Re: Yet Another TC-P55GT30 7 Blinkin...C board tested

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Thanks again for the help Moreno83, but I am a little confused. Is the way I tested mine as I described going from ground to each of the 12 (3 x 4) pins on the connectors that go from the buffers to the SC not a good test? I read somewhere here to do that. Your video suggest probing onto the connectors on the opposite side that attach to the screen lines. Can you please clarify this for me? Thanks

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Thank you for the reply Moreno83. Was the way I tested the buffer boards not correct? As I stated, I read somewhere on this forum to put my meter on continuity, ground one probe at a screw from the SU or SD board to the SC board and then test each of the 12 pins under the connectors on the SU and SD boards looking for low resistance readings. I'm hoping someone can confirm if this is an accurate way or not to prove these buffer boards. Like I said I want to fix it right the first time but don't want to replace any parts unnecessarily....

Re: Yet Another TC-P55GT30 7 Blinking Light Error

Well that didn't work. I thought I needed a reply post in order to start my first new thread but it's still restricting me. I guess I'll jump on here. I have a P55GT30 that got the 7 blinks of death the other day. I've read a bunch and here's what I've come up with. The SC board,with the 3 plugs from the SU a d SD boards as well as the white ribbon cable and tan/white power lead unplugged, is reading a dead short between the pins at SC2 on my meter. I understand that this indicates a bad SC board. On the SU and SD boards, with the...

Good info here. I'm having a similar problem. Going to start a new thread, but I needed to reply here to get a post so I can start a new thread as a new member. Thanks.
