Difetto : Spento
Telaio / Versione : QFU1.1E LA
Power Supply : FSP197-4FS01 2722 171 90676 REV : 01
Pannello : LTA550HQ19
Main board : 3104 308 98314

Il televisore si presenta completamente spento .
Le tensioni che leggo sono la 3v3s = 3v3 e la STB= 3v1 .
se scollego i cavi dalla main-board all' alimentatore i led non si illuminano .
Ho riprogrammato la spiflash 7CT3 (M25P10) , sul pin 2 del connettore 1M95 la alimentazione passata a livello logico basso , da 3v1 a 0 volts . La 12 volts , ora , presente , come le altre alimentazioni sulla main -board . Il led di indicazione frontale continua a rimanere spento . Il telecomando , e i tasto power della tastiera non rispondono ai comandi . Infatti se provo a spegnere il televisore da tastiera o telecomando sul pin2 di 1M95 rimane sempre livello logico basso .
Se lascio il televisore per circa 2 minuti con la spina di alimentazione inserita , sul pin2 di 1M95 la alimentazione da 0 volts passa a 3V1 , la 12 v ( logicamente ) non pi presente e il led rosso sul frontale del televisore lampeggia 2 volte .
attivando la procedura di servizio SDM il led mostra 5 lampeggi lenti e 3 lampeggi veloci ,  errore 53
 il bin che ho riprogrammato per la  SPI per un processore Fusion 77
Mentre il processore sulla main un Fusion P240 FNP202-B1E32 .
Pu essere questo il problema ?

Grazie e buon lavoro a tutti .

Hi Turnip

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

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

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 Jag,

Had dozens in for the problem. Funniest one was an old boy with a big Panasonic plasma of the period. To make the pound its a workshop job, as five minutes in the house makes folks feel they haven't had their money's worth.

Said chap just couldn't leave his set unplugged at night, even though we'd turned off updates and notifications after the factory reset. He came back time and again, eventually bought a new one and handed us a nice plasma to sell.

Admittedly we only charged for the first call, lots of heavy lifting though - Chris.

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.
