20 Most Recent V, Inc. Vizio P50HD Plasma Television Questions & Answers


Don't waste your money. Its not a good TV to fix. Vizio uses the cheapest parts in the industry. Its probably not your mainboard but the panel itself. Not cost effective. If you can help it try not to buy Vizio. I wont even take them in to fix at my shop they are so bad to repair. you fix one thing and another breaks immediately. I'm sorry to give this as advice but I would hate for you to waste money.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Hi,
I work as a contract technician for Vizio, and I can tell you from experience that replacing motherboard is one of the only solutions to this problem. The other solution if under warranty is to replace it. If you experience red, blue, or green pixels where dark shades (like nose, eyes, clothes, etc), call Vizio and accept nothing less than a full replacement! I have had situations where I replaced motherboard and within 2-3 hours the pixels return. Hope this helps.

Try viewing a source such as your cable box or computer on your TV. With this source playing, open the TV menu option. If the TV menu is also in black and white then there are a few components inside a plasma TV that can be causing your problem. If the menu appears in color but the video source your watching is in black and white the problem is probably with the source, such as your cable box or computer, rather than your TV. If the video and menu are in pure grayscale and the image is still clear the problem is likely the main board.

The first thing to check is if your power outlets have surge protector breakers. Try plugging in another simple appliance like a lamp into the outlet and make sure the outlet has power.
If the outlet is fine try plugging in the TV and listening very carefully from the back of the TV for a subtle click noise. The power supply has a mechanical relay that switches when the TV receives power. If you can not hear the click and there are no stand by or power lights illuminated then you likely have a power supply problem. This could range from a blown fuse to a bad capacitor up to a burnt out power regulator. Anything more serious than those problems may warrant simply replacing the whole power supply. Depending on your TV that board could cost anywhere from $50-$175. The power supply can be tested using a multimeter to determine if it is the source of the problem but this should not be attempted unless you have some electroics repair training and are aware of the dangers involved in working on high voltage electronics.

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_17_2012_4_39_01_pm.jpg

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.

The z-sustain board is bad. One of the the heat sinks on the board is cool to the touch. These had LG circuit boards and the number on the sticker, on the board, was a good LG part number. The part numbers were 6871QZH044A.

Do a search on the internet with Google, Yahoo, or Ebay with this part number. The board unplugs and the new one plugs back up. Not an advanced technical repair. Unplug the set and take the back off and match the picture on Ebay with the one in your set. And especially match the part numer.

Contact the manufacturer and they should be able to determine the date the tv was made using the serial number, or you can try getting a copy of a receipt from the retailer, as well if you have your warranty card it may have the date of purchase and could help in getting it repaired under warranty. I hope this helps, Good Luck.

Hi,

You need to unplug the unit for few minutes, say 30 minutes and then turn it ON. If the problem persists, it would confirm an internal failure.There are a couple of different things that could cause this problem, the first is the power supply, and the second the main board. Also either sustain or scan driver board can cause this problem. To know exactly what board is the cause, you need to have electronic repair experience, and test equipment. If you have this let me know and I will assist you in the troubleshooting of this tv. Otherwise you will need a repairman at this point. You can expect a bill of anywhere between $400-$700, this is a good average, however it could be more or less.
I am sorry I don't have a quick fix or easy answer for you on this one, please let me know if you have the skills and tools and I will be happy to assist you. Also please let me know if there is anything else I can do for you.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Is the power switch on or is there a bad connection from the plug? Check all connections if there is still a problem then there might be something wrong with your inverter board.

what you will want to do is go into the users guide and find the reset factory defaults option usually it involves holding a button or two while starting the device however are sometimes very different this will ensure any issue is not software or programming related may save you some time


hope this helps

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.

Your TV is going into fault protection mode. The Uf capacitors on the PSB-Power supply boards are blown. Recap the Uf caps on the PSB.
