Re: Panasonic tx55cr730b no picture
Hi all, just an update none of the above things worked. As we had changed the av board, I got my brother to put the original one back in and hey presto the tv is alive!!
I can send the replacement av board back so not a bad result.
Thank you for all your help and time.

Re: Panasonic tx55cr730b no picture
Hi, my brother managed to get a new tcon board before I have got chance to have a look at the tv. It now has the colour test screen cycling red, green, blue ect...
Any idea how to get out of it?

Re: Panasonic tx55cr730b no picture
Thanks for the replies. I'm at work at the minute but I've had a mess earlier.
I can get sound but no picture even doing the the flash light trick. I pulled each ribbon from the tcon board and made no difference.
Does this point to the tcon board?
I will get pictures up tomorrow.

Re: Panasonic tx55cr730b no picture
Hi all, changed the av/main board but still getting a no picture and a clicking sound from the new board.
Still turns on as it should no flashing red light.
There is two power boards in this tv, if I pull any cable out of the av board the tv doesn't power on.
Any help would be great.Leave a comment:

Re: Panasonic tx55cr730b no picture
Yeah sorry forgot to say back lights come on and stay on. It looks like the back lights change if I press source or tv buttons on remote. It's only slight but something is happening.

Re: Panasonic tx55cr730b no picture
To be honest I've just had a quick mess about in the back, no major investigation. If I pull any of the cables out of the av board the tv wont turn on at all. So that's as far as ive gotten.
Clicky av board and normal reactions from the remote.
I will have to get the multimeter out. So hoping someone may of had the same symptoms as mine and kind of say yeah 99% this board.

Panasonic tx55cr730b no picture
Hi. I have a Panasonic tx55cr730b which doesn't display a picture (no start up logo, no menus). It does show a green power light, goes into and out of standby fine. When the green light is on I can hear clicking from the av board. Would thus suggest that the av boards is faulty or a power board issue.
Any help would he great.

I will get l lvds cable when I know what spare cash I've got. I can of course sell all the bits I've bought as a job lot to make some money back.Leave a comment:

Re: Samsung ue48h6400 horizontal lines
It's the same kind of lines but just lower down the screen. The new tcon board came with the 2 ribbons so changed them to. I've put the original main board back in so these moved lines are from that board. Should I just get a replacement cable? Only board left to change is the power board.Leave a comment:

Re: Samsung ue48h6400 horizontal lines
The lines have changed recently moved down the screen. Does that rule out the cable?Leave a comment:

Re: Samsung ue48h6400 horizontal lines

Re: Samsung ue48h6400 horizontal lines
I've got a main board coming this week, £21 delivered. Couldn't really say no at the price. Hopefully it will be here Friday. Fingers crossed that it resolves my issue.Leave a comment:

Re: Samsung ue48h6400 horizontal lines
First thing I will do is put pressure on the mainboard to see if it does anything.Leave a comment:

Re: Samsung ue48h6400 horizontal lines

Re: Samsung ue48h6400 horizontal lines
Haha I could do that but the misses wouldn't be to impressed if I finished the tv off. I could order a replacement lvds cable to test that.Leave a comment:

Re: Samsung ue48h6400 horizontal lines
The lines haven't changed at all from before and after the lvds clean and reseat. they didn't change when I replaced the tcon. I haven't had the back off the tvs to test pressure on the ic1001, but will try to get time over the weekend.Leave a comment:
