Re: Make slave AV screen....
The 4 wire goes from the PCB into the screen. There is also another ribbon cable going from the screen to the PCB. I dont want it to be touch screen, i just want it to very simple, i.e turns on and instantly plays feed from AV.
To explain, it is a car dvd player, mounted on the drivers head rest. I have another one on the passengers head rest, that i want to use as the master & feed this one as its so difficult to operate being the driver. So im willing to basically scrap all the current electronics, fit a control board to just take AV and...

Make slave AV screen....
Is it possible to make a LCD screen so that i can accept AV IN from another source. i have a 10" LCD (or TVF screen) that i just want to be able to power up and work with an AV Input.
The screen is xianchuang m101wsb40 (touch screen) per attached photos with two ribbon cables. What components would i need to make it work??...

Re: Samsung PS51E450A1WXXU (Live coax potential cause)
This is how i checked per first post - used DMM on the test points with one probe, the other on the chassis and turning on the set with the remote.
Since the 230V was removed from the co-ax the set has no been tripping the ECB. There is sound just no picture....

Re: Samsung PS51E450A1WXXU (Live coax potential cause)
Update
Have read through alot of treads and its seems “If Vsc is low or missing and Vs was OK, the failure is with the Y/X-Board since the Y- Board section generates the Vsc voltage from the Vs supplied by the SMPS.”
Was going to just try change the Y-main board and found one, LJ41-10181A, FB 880A A7 28P 3GL – AA7, but I have a FB 880A A6 27P 1HN – AA6, however the printed LJ41 #'s are the same, but the sticker is different, so will that be a problem – sorry I don't know what these stickers mean....

Samsung PS51E450A1WXXU (Live coax potential cause)
Hi - having a problem where i have sound but no picture at all. Not sure if its related to an issue i discovered where i have a sat receiver in my attic, during the recent cold spell, condensate manged to drip on this receiver, shorting somehow but making the coax output live - therefore 230 AC was presented to the receiver board of the TV (seems too much of a coincidence but lets see)
Remove the back panel - green LED on the logic boards is on for ~ 5 sec, off for 2 etc.
Examined all boards (with limited knowledge) but didn't see anything out of the ordinary!
