The main power supply fuse will be located on the power board. Just follow the power cord to the power board, the fuse will be close to the power connector. FYI, there are also fuses located on the main board, t-con, and inverter boards.

My Vizio VF550XVT1A shows the picture in the top 1/4 of the screen. The bottom 3/4 is lined and static. I think it's the T-Con board. Any advice?


yes tried to re seat the LVDS cable first, if can not get with re seating the cable check for cold soldered parts in the t-con board otherwise just replaced it.

No tv sound. Dvd works alright. Have hdmi cable from theater sys. to tv. Cannot figure out how connect red,white or yellow cables.


By Visio "55 I'm presuming you mean the Vizio VF550XVT.

First you need an Audio Cable (Red/White RCA Connectors) and with everything turned off connect it to your TV where shown below.

The other end of the cable will then connect to the Aux In 2 of your Samsung HT-Z320 as shown below.

Once connected you can turn your Vizio & Samsung back on.

You then need to use the AUX button on your Samsung Remote Control to Select Aux 2.

And on your Vizio Remote Control follow the Instructions below.

Picture flickers while watching


When the flickering changes if you 'bang' a bit on your TV you have bad electrical connection somewhere

My 55" vizio randomly shuts


I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

I have a "Spyder3TV" gizmo that worked very well for all my 3 HD tv's.
Takes about 30-60 mins to run all settings and costs?????? I bought it about a year ago. Search on the net for it.
