Title: JVC black screen with sound
Post by: Norm67 on June 16, 2019,13:08:18

Hi, hope for some help, I have a JVC LT40C540 LED tv. It was working fine when I switched off but after a few hours turned tv back on and had a black screen with sound. Tried switching on and off, unplugging overnight but no success, any advise please.

Hi Michael, not sure about mount, I turned it on and I saw a faint JVC on start up and a bit of light through back panel

Hi Norm,

Had one - attach file - Good luck - Chris.

JVC LT-40C540   Led Backlight    Mfd 2014
Power/Inverter - TV3902-2C02-01(D)    M07/A52624/04
Main – M78/A52624/13   510-140910139-00565
Screen – LSC400HM09-G-S
T/con – LSC400HM09-G01
Links
14/10/15 Steve Onion – Goes off in seconds. Turned it on – brief flash then S/by. Tried again – Flash and a crackle, stayed on. Suspected dries – CON302 and CON303 feed to screen LEDS resoldered - OK

Otherwise duff screen Leds where you need take the screen off - Carefully - Set should fire up with screen removed so you can sort any S/C ones. If any O/C you might have a problem needing a screen Led tester - Cheap though.

Hi Turnip

Not able to click on any links, are you saying I should take off screen and look at LEDs?

Hi Norm,

Sorry for late reply. Guess shouldn't have attached my file as maybe confusing. Vestel sets are famed for duff Led issues as they mostly used LG Leds - Chris.
