Question about Televison & Video

Open Question

Have LG 42v5. Suspect YSUS faulty. Output waveform not exactly like service manual. Leds D1 & 2 lit. D17 flashing. D13 lit. D12,11, 10 not lit. Sometimes the screen shows some signs of life (the odd blue pixel lighting up at top of pic). ZSUS waveform looks ok. Control panel & right XSUS have been changed. The original YSUS had blown and I replaced it with a supposedly working one from a dealer. The Y buffers have also been changed. Please help, regards, Mike

SOURCE: Some troubleshooting help please.

The part that caused the fuse to blow is the hybrid that is mounted underneath the heatsink on the YSUS and ZSUS boards. The part used on these boards might be YPPD-J017C or YPPD-J018C, in about 90% of the time, replacing these hybrids fixes the plasmas with no video but good audio. Since VS and GND is shorted, that means that the hybrid has shorted internally. Most service techs would rather replace the entire YSUS or ZSUS boards since the hybrids are very difficult to remove.
Let me know if you require further assistance.

I’m not seeing a direct break down of that 42” Y-Sustain board to see the D1, D7, and D12.\
Look below for the complete diode parts locations, part numbers, and ratings for the 42PC3d-UE.AUSLLJR. That TV has the 6871QYH053B board you asked about.
I hope my information has helped you.
Good Luck.

It sounds like a Hitachi--black diodes not the issue--the green ones if Hitachi (how about a model number?) monitor voltages, if they are not lit it means a voltage is not there---look to see if more than 4 green leds and to see if any not lit.

TA-N9000ES Amp - Standby light constantly blinks - no sound

The flashing light is indicating that a fault has been detected, and it is staying in "protect mode". First disconnect all cables from the processor (except the power cord) and then power up the processor. This will eliminate the possibility of a shorted cable or a problem with any connected components. f the light still flashes, there is an internal problem and the processor will require profesional service.
