Re: Lg42 ls 5600
See if you can turn down the backlights, NOT brightness, see if the tv stays on longer, if it does it's more than likely problem with led/s in the backlights.Last edited by nomoresonys; 10-17-2019, 07:44 PM.Comment

Re: Lg42 ls 5600
Can we at least see the whole backside of the TV showing all the boards and also the pictures of the whole power supply board?
Did you do any Voltage testing at all?Never stop learning

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help. -
When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem? -
Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
