Yet another 19" TV here in the maintenance shop. This one belongs to my 95 year old mom so I'd really like to get it fixed for her.
Samsung UN19F4000AF. Back home for a week, I found this TV in her master bathroom unplugged and not connected to anything. Would start to power up and make about half of the Samsung startup chime, then shut back down.
Brought it back home with me but after having a quick look it no longer tries to start up and does not have the red LED lit in the IR receiver/switch thing.
Power supply is good, tested it on an exact same set that I picked up on FB marketplace for $20. Could just bring that one back to mom but I'd like to repair hers if possible.
This is a one-board set using what appears to be the BN41-01989 board. Pictures attached for ID and reference.
Any ideas where to start? Componets are all pretty much SMD but there must be some parts of the power circut that I could do some testing on.
