Vizio P50HDM is dead

I opened the TV up and found the Z sus board to be shorted. It has a short from VS to ground and is blowing the fuse on the Y board. Can I just replace the Z board, or do you have to repalce as a set? I relay cant afford to replace both , but dont want to do one then the other goes in a week.

Measure the -Vy and Vsc on the Y Sus board. If there are no voltage reading then you have to replace both of them.

Hope this will help!

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.

Which one is the main power fuse in a vizio 42


The main power fuse is not to far from where the power connector plugs into the power board. If this fuse is constantly blowing, you have a dead short on your power supply board.

Number one fuse on my main board is deadl vizio gv47l hd tv 10 amp


If fuse is dead, there must be some reason for that. Some short circuit or so. Without rectifying the fault, if you replace it with an other fuse, the fuse you insert will also blow out, and might make more faults to occur. The rating of fuse will be marked on the printed circuit board itself, very near to the fuse.

Hi:
This is the X-systain board replace this board and your problem will be solved. The part number can be found on a white sticker some where on the board. Get the number and google it or enter it on E-Bay because alot of shops sell these boards when the get units with bad screens. Or try www.shopjimmy.com for a new board.

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.

Vizio p50hdm loud pop from inside tv now screen is dim


Hi there! This could be as a result of several boards. Y-sus, Z-Sus or power supply. One would need to check that all the relevant Voltages on the power supply are actually present. Next would be to check the Fuses on either Y or Z-Sus boards. The board with the fuse blown would most likely be the one at fault. However it blows for a reason so replacing the fuse on these boards will probably not help. But it is worth a shot. If all else fails refer to a repairer. If you can get the boards and want to try doing it yourself it may or may not prove to be successful. Please beware of HIGH CURRENT before you proceed. Best Wishes and Good Luck, JUS004

Vizio p50hdm red flashing pixels


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.

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.

P50HDM ... pop of death again


PLEASE READ THIS. I bought my P50HDM back in December 2005 at Costco. The 'Pop of death' hit last night. I called Vizio today and the tech person told me the warranty had expired. Nothing they could do except set up an appointment for a service call for which I would be responsible. When searching the web today I saw a post in which someone reported that they had also bought there P50 at Costco and that after calling the Costco concierge program @ 1-866-861-0450, they found out their TV was still in warranty even though it was also several years old. I called Costco, excellent people to deal with, and told them my problem. They entered Model# and Serial# into their system and informed me my set was still under warranty. From here the Costco technician calls Vizio direct and puts you on a three way call. In my case it took 25 minutes of waiting, I did not mind, and the Costco tech told she had to go through three levels of Vizio techs to get the correct person. I spoke directly with the Vizio representative as the Costco tech listened in. The Vizio tech apologized and said "YES, THIS IS A KNOWN PROBLEM" with th P50 and it is still under warranty and they will repair it for FREE. This is for real. If you bought through Costco call the above number and let them handle the Vizio people. If not, call Vizio and insist on speaking with a supervisor until they admit there is a problem with the P50 and they agree to repair it. They are apparently taught to reply that your warranty has expired, but when this amount of money is on the line you should push until they agree to fix at their cost. Please do not let Vizio tell you the warranty has expired bit, they have to fix it because it is a defective design. Call and do not let up, you will save a small fortune.
