How do I repair a Vizio P652ui-B2 HDTV that has an all white screen shortly after boot up? Vaguely can make out menus and apps.

I have a Vizio P652ui-B2 that now displays a white screen after boot up. Though it starts gray it quickly turns white with vertical bars. It's nearly pure white though I can vaguely see the menus underneath but not enough to make out much more than the Netflix logo, etc. Serial begins LWZAR. Purchased from Best Buy in early 2015. This is the 4K model.

SOURCE: the screen has lost its brightness

Someone has probably changed the brightness settings. Increase the brightness and see if this resolves the issue. If it does not then I would assume that the monitor's backlight is a toast and you may have to install a new backlight.

SOURCE: I'm also experiencing same sort of white screen problem.

To determine if the LCD screen or the video card is faulty, connect an external monitor to the video connector on the laptop. Power up the external monitor first and then the laptop. The video should divert automatically to the external monitor and if you get a normal image then the video card is OK and the fault could be the LCD screen or the video cable. Reseating the video cable and connector on the motherboard could fix yout problem.

SOURCE: Just purchased a Vizio 37" HDTV with Netflix app

The Vizio does not have Internet capabilities. You need to hook up a computer via the VGA or HDMI port. Then youor computer controls what you do with the intenet.

SOURCE: Gray vertical bars on screen but no picture

It sounds like you might have shorted out the display panel driver board / boards.
These boards are located at the bottom of the screen and are prone to liquid damage.
Just before this happened, did you happen to spill something on the screen or clean the screen using a spray bottle cleaner?
The only fix I know of is to replace the whole panel but it is usually just as cheap to buy a new TV.

Testimonial: "Thank you, Ken. It is quite possible it was sprayed with a cleaner to clean the screen."

I have a Vizio TV Model P652ui-B2. A few days ago started to go off and on for a short time but around every 10 or 20 minutes sometimes longer, but it comes right on again.


The tv has most likely filled upi with dust on the inside. This will cause it to overheat and shut down. When it cools it comes back on. the only way to fix this is to get the dust out of the inside. Make sure all the vent holes around the outside case are not blocked by dust. The only way to get the dust out of the inside is to have a qualified person open the case and blow the dust out.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Vizio m470nv will not come on, logo blinks orange to white.


It may not be the caps at all, a lot of the new LED Back-Lit TV have faulty LEDs. They short and pull down the power supply, and to a novice it will seem like a bad power supply. That means that you must replace the bad LED's in that particular LED strip before you can fix the problem. Not an easy repair for a rookie.
