Vizio Y Sus Z Sus Replacement Questions

Re: Vizio Y Sus Z Sus Replacement Questions

Mr PlainBill, thank you for the suggestions. I will try to find someone with superior soldering skills to install the repair kit for me. Coppel TV repair is the company that I was going to buy from on eBay. They actually offer a "fix or replace" option where you pay like $70 (this includes shipping) and send your board. They probably will do the same fix as in the repair kit and send the unit back. Coppel claimed that the Z sustain fails 90% of the time if the Y failed first.

Unless I find a better board.

Anyone know why the board makes the popping noise initially, just before the video goes out? Assuming it's not the capacitors...

Components on the hybrid exploding.

Re: Vizio Y Sus Z Sus Replacement Questions

I'm trying to find a "new" y sustain, but all I find are "refurbished, recertified, used" etc.
This site has one for $150, but I can't tell if it is used http://www.shopjimmy.com/ysus-6871qyh953a.htm

Any ideas?

Oh and can you guys recommend what kind of physical damage I can look for on the boards to identify other issues the Vizio might have?

The "pop" sound is the classic sign of the IPM hybrid taking a nosedive to the china electronics junk of junk hell

Find and replace the bad IPM. BTW i have that Y-sus kicking around though. from a boardset someone gave me. no idea if it works, no idea ifi its blown, but im treating it as blown and tossed it in the parts bin.

Re: Vizio Y Sus Z Sus Replacement Questions

I was pulling the tabs off the z sustain to remove it, and one of them got torn. It wouldn't budge out of the connector without being ripped for some reason.

Is this the end of my TV repair project? Will this new damage prevent normal operation? Those gold tabs seem to connect directly to the screen.

One photo shows the attachment thinga-magiga that was pulled ok and the other that got ripped....

As long as the other end didn't get torn you should be able to clean this up and it should work. There are no individual traces, it's a flat conductive strip.

I got busy and put the project aside for a while... but before I order a replacement y sus..
Can you guys verify that it is diagnostic when the tv is run for several hours and the y sus is not as hot as the z sus. During normal conditions, do they heat up about the same?

Thanks for all ya'll's' help!

OK, so here is the outcome:
I got the hybrid ICU replaced through Coppell TV repair (ebay). Mr PlainBill, you were correct, of course, about the "pop of death" resulting from components on the hybrid exploding. With the two big caps on the PCB and the hybrid replacement, the fix cost about $120 total.
Thank you all for advising me along the way. Another good TV saved from a landfill!

Re: Vizio Y Sus Z Sus Replacement Questions

good to hear you got it going, I have a similar situation (I posted in another thread but nobody is helping yet) I have replaced the hybrid and now I have the "tries to turn on, then turns back off" as PlainBill puts it, how can I tell for sure if the caps on the pcb are bad? I have read the guides on here but i'm still learning,,, I need to discharge them first right? Thanks!

Re: Vizio Y Sus Z Sus Replacement Questions

POP OF DEATH: STRIKES BACK
The TV ran for probably 6 hours, on and off, and everything was great. I saw a little red snow at first but the picture was excellent for the duration of the six hours... and then - POP!
What do you guys think? I am willing to get a whole new y zuz and/or z sus now that I know the TV can be saved.
I really don't see any bad caps any where. And, Coppell Repair charged me $90 for the parts and labor and shipping to replace the hybrid ICU. Not sure if they guarantee anything at this point.

Any suggestions?
