Pulse Flashing Vizio E470VA

My Vizio E470VA has a pulsing rhythmic flashing when first turned on. It can be seen when the input display first shows up and when there is a picture on screen. It doesn't always happen when turned on. As a fix, I can turn off the TV then turn it back on and it usually fixes the problem but sometimes it takes a few times of doing so. I've done a factory reset and it hasn't seemed to help. I've also messed with all the video settings hoping it would help. I'm pretty ignorant of what would be happening on an internal electronics level. Any ideas of what's happening?

SOURCE: Vizio GV42L LCD TV screen black when turn TV on first time

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

Don't replace anything, Vizio has issued a lifetime warranty for this set because of this problem. No joke, call the customer service line and tell them you got the pop of death. They'll send someone out to 'repair' the set free of charge. If they can't fix it they'll give you a new one. Even if your mfg purchase warranty has expired. Call them and post the results. I've been fixing TV's longer than I care to admit and this is the first time I've actually seen a company stand behind their products like this. I bought a broken tv with the intent of fixing it and after replacing almost every board I could only manage to get the vertical racing stripe line, except mine was purple. I put it all back together and called to find out if there was a recall on this set and within 5 minutes the (Actual English speaking) gentleman told me to sit tight and he'd have a repairman come and do his thing. He did, and long story short, he couldn't fix it. Last week they delivered a new TV to replace this one. I was shocked. I think Vizio will have all my future business.
Good luck.

SOURCE: Vizio LCD Green Pixels

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs.  After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support.  They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables.  So far, so good.

SOURCE: How to reset tv. Have sound but black screen

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.

JRC 1000 MKII bearing pulse error on receiver screen. Connections to scanner good and scanner turning. How can I determine if the problem is in the receiver? How can I fix it? louonboard

Normally the bearing pulse comes from the bearing pulse generator built inside the motor. Every time the motor turns it sends a pulse down the line showing the radar that it is indeed spinning. There is also a Heading pulse that comes from an electric eye elsewhere in the housing. The other thing could be that the wire carrying the bearing pulse is not getting back to the display. More so than often, it's the motor. I would have the display sent out to be checked on a simulator if there is a marine electronicshop nearby.

Mini hi-fi JVC CA-FSX3 stops after power on

Well, I disassembled the unit carefully. And I've found that diode SR303 was blown. It's very easy to find near huge pulse-code converter chip. This diode is used at power supply stabilization for amplifier that has a D-class i.e. pulse-code amplifier, and for CD part. Testing of this diode confirmed that it's dead. After a couple of days received the diode from shop, is very cheap. Changing the diode recovered all the functions of the unit. Now it works fine.
Resume: The diode was burned as a result of incorrect connection to line input. The owner of the unit haven't seen that a volume level was at maximum. The connection of line input overloaded the maximum current capacity of the diode and it was blown. As for it, I've seen that in that circuit in reality must be used a stabilization chip, that is not so cheap like a diode. I think it's a constructor's error to change the chip, that is overload protected, to a simple diode.
Waiting that my info will be useful because it´s a most vulnerable part of JVC CA-FSX3. And don't overload the amplifier!
