Hi guys I honestly did not know whether to post this as a TV or a monitor - but it is being used with an HDMI converter as an outdoor TV at a local hotel swimming pool bar so I put it here
@moderators - move this thread to monitors if preferred
OK so I have a Dynascan DS551LT4 on my bench
http://www.dynascanusa.com/product/5...ezel-ds551lt4/
Anyone here familiar with these? It powers up, I have 12V from the little smps supply, and LED the backlights are working.
It actually goes through a sequence of a green LED lighting on the logic board, then a green LEd flashes on the other board, then a red led flashes on the logic board, a relay clicks and the backlights come on. So it's not 'brain dead'.
However I get no video, not even menu from the remote or the 'no signal' box. The hotel has two of these so I know the external hdmi converter box is working ok.
Something has burnt out on a connector on one of the PCBs (the one where a green LED flashes once on power up) - but I don't know what this PCB does as I have not seen anything quite like this in LCD TVs. It looks more like a plasma X buffer or Y buffer board to me but this is LCD
The two wires from the burnt out connector feed with some other wires into a cable and the other end of this cable disappears under the metal work at the corner of the LCD panel. There also looks to be a bad cap on he PCB near this burnt out connector. There seem to be similar cables going to other corners of the panel.
There is another board maybe Tcon underneath the main logic board right at teh front of the panel, it's hard to see as it is partially obscured by metalwork.
Please see pics and any advice welcomed, I'm a bit out of my experience with this one TBH.
Cheers
Rich
PS I put Cynascan instead of Dynascan in the thread title but seem unable to edit it
