Hello all, I have this LG TV M2762D-PC, this is a combination of TV and computerscreen. Bought it in april 2010. Use it as a TV and worked great till yesterday. 10 seconds after powering up, the display went black, sound was still ok. The remote control still worked for on/off and volume, but could not change channel anymore. I managed to open the TV and take out power supply. PCB 3PAGC20002A-R
No bad caps but one burned BLUE ceramic ‘C’. There is nothing marked on this ‘C’, so I don’t know what value this is. It looks the same as the other blue ‘C’s on the pcb. 1/ anyone can tell me what value this ceramic ‘C’ is? 2/ I guess this is not a multilayer pcb. As you can see the damage on the pcb, is it still ok to repair this pcb by replacing the ‘C’ or should I look for a replacement pcb? I already have done some repair on monitors (bad caps) and mobile phones (replace digitizer and lcd), so I can handle a solder gun. :-)
Thanks for reading and even more thanks for any answer that can help. Pierre. UPDATE 03/03/2015: Today I managed to take a macro photo and see some identification on the other ceramic capacitors. It says: .LY SL6KV 5D
I think this is high voltage capacitor (6KV) Anyone can help? Where to buy these? UPDATE 21/08/2016 Almost one and a half year later, after replacing the burned capacitor and replacing the other one that changed color as well, the unit is still working, but there was this burning smell… The pcb now looks like this!!
Is it the chemical residue from the old burned capacitor that caused these damage? Time to look for another pcb I guess… Any suggestion welcome.
Pierre, that is a Ceramic Disc Capacitors .LV SL6KV 5D = 5pF (0.5) & 6kV (6000v) (5pf 6000V Tolerance=+/- 0.5pf). Available at Mouser.com part No: 81-DEC1X3J050DC4BMS1
Hola Pierre, siento no contestar en ingles, te explico lo que yo comenzaría hacer, primero desoldar ese condensador quemado, limpiar en lo posible la mancha negra de la placa, y así intentar ver la numeración donde estaba ese condensador quemado (C4xx), si no puedes ver la numeración yo me fijaría justo al lado contrario de la placa donde hay 4 condensadores azules y ver cual numero (C4xx) es el que no se repite comparando ambos lados, y el que no se repita pues intentar soldar y probar, yo apostaria por el C402, saludos, espero ayudar en algo es mi primer post en ifixit.
