    I had the same thing happen to mine. I took it to a Vizio registered repair center and they said the screen must be bad b/c all the repairs they attempted did not fix the problem. Let me know if you get it fixed. I've had the TV for a year and a half, it's sitting in my basement collecting dust!!

    Well I gave Costco a shot and they wouldn't warranty it because it was a month past. They basically gave me the CS number to Vizio and told me not to let the door hit me on the way out....less than satisfied with the 'concierge service'. The part numbers you recommended are different from the boards in my set, are they interchangeable, is there a newer version of the board that is better to get than another?

    axle80 -

    what were your symptoms, as in what exactly happened to your tv?

    I called up VIZIO today and they told me that the TV was out of warranty. I noticed that LEDs D16 and D17 on my LVDS board do not light up. Does anyone know what the voltages on the Z sustain board are supposed to be?

    What phone number did you call?

  • Anonymous May 06, 2009

    I called Vizio but because I bought the TV used on Craigslist, they said they would not warranty it. They referred me to an authorized repair center. I guess I'm gonna have to try to swap the boards myself.

Hey guess what?! After Costco shafted me good, told me to get lost, and slammed the concierge phone down, I called Vizio. THIS TV HAS A LIFETIME WARRANTY ON IT NOW!! They will fix/replace it at their expense! After a 5 minute call to their customer service they arranged the repair order. Vizio knows that this set is a lemon and they are actually owning up to it. The gentleman told me that this set now carries a Lifetime warranty on parts (to exclude a shattered screen of course) and labor! The repairman is going to come this way in the next week or so and I'll update you on what he says. So to all out there with problems on this set: CALL VIZIO AND GET READY FOR A BREATH OF FRESH AIR!

    My tv got the pop of death. No sound no picture. The led would come on and flash orange and green 8 times then shut itself off. The vizio guys came today and found the exact same thing I did. After replacing EVERY board in the set they were able to only get a weird vertical purple stripe to appear. So after a call in to the HQ I will be getting a brand spankin new set by the end of the week. So long story short. ********CALL VIZIO FIRST! THEY WARRANTY THIS TV FOR LIFE******** no joke, they are replacing this set. Its nice to see a company stand behind their products. Sure wish S0NY would do it, when there stuff has obvious defects they just ask you to bend over and make use of the broom handle.

    Something to note with this TV. I am NOT the original owner, I never registered the TV nor do I have any paperwork to back anything up. And it didn't matter one bit to the Vizio CS guy. He told me frankly that it didn't matter who ended up with the set, That particular model was under warranty with or without documentation. I think I have found a new favorite brand.

    Just as suspected, the repairman came and did his thing. It was actually pretty funny to have an old fat guy try to explain to me in terms that a 16 year old girl would understand, "your tv, sir, has large green circuit boards in it, they use electricity to generate signals displayed on the screen, each one has a function like blocks making a tower. If one stops then the tower might fall or in other words your tv stops working, I think your problem is in a large board here called the Y board. It...." I stop him short and say " I've swapped the Ysus and the Xsus without success, the buffers all are running correctly, all voltages on the PSB came out correctly or within 2 volts, did vizio send you with a logic main to replace the old one? Let me save you some time, it can't be fixed."

    The guy offered me a job on the spot. I laughed and thanked him anyway. He phoned in the result and a week later I got a call from the Delivery guru, he's going to show up next week with a brand spankin' new set. I will repost again with the model number of the new TV.

    March 25th, they replaced it with a VP50HDTVA10. Looks nearly the same with some added styling. Appears brand new. It certainly doesn't look or perform like a refurbished model. It actually came in a mfg box which they used to repack the old lemon. Good luck to everyone. Post if you get a different result from Vizio. I'd like to know how everyone else's experiences are turning out.

Replace the Z Sustainer Board, Part # 6871QZH044B and replace the Y Sustainter Board, Part # 6871QYH039B at the same time. If you replace one and not the other the bad one will end up shorting the good one and you’ll lose your picture within a week. You can do this work yourself by unplugging the unit and placing it face down on carpet (put down a soft blanket to protect the screen) and unscrewing the back of the unit (a power screw driver works great for this job because there are a few screws involved). The cheapest place to buy these two parts are: www.discount-merchant.com , or www.avextra.net, or www.ebay.com

    Oops, I forgot to mention the most important part of the P50HDM Pop of Death. If you purchased that unit at Costco then call their Concierge Service at (866) 861-0450 for Service and DON'T PURCHASE ANY BOARDS let them come fix the problem. Costco is aware of the POP on the P50HDM and is committed to making it good even if the TV is 2 or 3 years out of warranty. Costco probably took in the shorts with this model but they stand behind their electronics. However, if you let your Costco membership lapse since you purchased the TV then they won't provide that service, it's only for members with active memberships. In the end they will eventually give you a brand new Vizio 50" TV from their stock and put your damaged P50HDM in the box of the new Vizio 50" 720p Plasma (so you'll drive home with the TV but no box) and send the damaged one back to Vizio. But the best thing is that the new 50" Vizio 720p Plasmas have an estimated life of 50,000 hours where as the P50HDM's only had an estimated life of 10,000 hours (the difference in hours sure makes it appear that Vizio knew about the problem when they manufactured the unit). So the replacement TV should last for many more years than the P50HDM.

Just so you know, VIZIO is no longer standing behind its "lifetime warranty". Someone at "corporate" headquarters made the decision to end the warranty for this issue May 2013. You'll be given the number of a servicing technical contractor who is more than happy to come to your home and charge $500 plus to address your concerns.

I called Vizio prior to seeing this posting and was sent to a service company that wanted $525.00 to fix the t.v. I was searching the web trying find what was wrong and fix it myself.. Then I read your posting called Vizio back and told them I heard the the P50HDM had a lifetime warranty.. I was asked if I heard a POP.. I told them yes and was forwarded to another person who set up a tech to come out and service the t.v. (free of charge).. I am glad I found this information.. They say they are aware of the problem with the t.v. and will replace the bad components..

You can opt to repair the Y board by replace the following components: ic12, ic4, hs1, x1, ic18.
LG has also updated the large silver IC modules but it's not necessary.

I have a Vizio p50hdm while watching heard a pop noise and tv went out cant turn back on.I replaced main board and power board and still doesn't come on any Ideas?


The power amplifier chip (which goes "pop" when it goes bad) may be located on the board where the IR sensor is. Sometimes (but not always) you can make the TV come on by holding the power button in _until_ the TV comes on. But that usually only works when the chip is "going" bad. If you heard the pop, it's probably shot. Also, check for a fuse on _any_ of the boards, and possibly a main fuse at the back of the TV.

Picture went out on Vizio P50HDM


Check you voltages before just swapping out boards. Although a YSUS is common for no picture, so is your upper and lower Y Buffer boards or the panel itself. Check youe -VSC voltage. Does it look like it is being loaded down? If so then your YSUS is not the problem. You can run the set with just the upper or lower Y Buffer boards untill the load is gone. That will let you know wich board to replace.

Try to adjust the Vs voltage on the power supply by lower it a little bit or increase it a little bit. It will help to decrease the red pixel flashing.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

Vizio P50HDM


Dan, The they are actually called Z sus and Y sus boards.. They are the 2 boards that are on the direct right and direct left of the panal at the connections. You can find the replacement boards on ebay pretty cheap.. However most of the time all it is is a blown cap. Worst case its a blown fet, but if your good with a meter, you can find the problem in about 5min and replace the defective components and be back on your feet for less than $10. This is all high voltage stuff, so somtimes components fail due to mass production and toleranace.

If you bought it at costco call their Conciere service and they will send out a techie to repair it at their cost, even if it's out of warranty (so long as you kept your membership current). If you didn't get it at costco go to google and put it P50HDM Pop and there are plenty of answers to your problems. I've even posted a few myself.
