Question about Televison & Video

Open Question

I have a Vizio VW37LHDTV20A that I am having trouble with. It will not power on, however when plugged in the orange LED Vizio logo stays lit. When I press the power button, the set does not respond. Here's what I've found so far: I get 5v coming in through the power supply for standby, and all the caps look and test fine. I've also tested the resistors, one of which was not testing correctly and I replaced it, and still the same exact issue. I get 5v at the main board as well, and all the caps look fine there, too. I've tested the physical power switch and it tests out ok, and I get 2.2v. I also get 2.2v at the main board, but I can't track down where the signal terminates. I would assume this is a main board/processor issue, but I'm stumped and would like some advice. Even some test point help would be great. Thanks!

SOURCE: relay click and 9 blinking led.

Try the following steps:
1. Remove the power supply to X Main board, check VE. If you get normal VE then replace the X Main board. Otherwise to 2.
2. Remove the power supply to Y Main board, check VE. If you get VE then replace the Y Main board, otherwise to 3.
3. Replace the SMPS board & SMPS 200V board.

Good Luck

Yes it does sound like the mainboard. But we have to confirm. I will see if there is a service manual for this unit in my collection but do you think you can safely work on it? Have you worked on electronics before? The last thing I want is you hurting yourself trying to fix it. HV circuits are not to be messed with unless you know about them.

SOURCE: VIZIO GV42LHDTV Got TV after

Hi.

If the TV does not start with the new audio board, and if it does start with the old one, then the audio board that you recently purchased is defective.

About the board : 0500-0507-0230; that is the power board (PSU). If you could see the Vizio logo, that means that TV started, and that the power board was OK without need for testing. When the power board is defective, either the TV does not give any sign of life, or the TV goes in standby mode from start and does not wake up. In that case the led stays blinking to warn you that there is an incorrect voltage from PSU.

If the TV is freezing with Vizio logo, that means that at most the faulty part is the main board.

Also, you say that there is no backlight. No backlight means that the screen is completely dark. If there is no backlight you won't be able to see the logo or any other picture.If there is no backlight, then the problem is usually the inverter.

Here a brief article summarizing how to test PSU and inverter: How to test an LCD TV.

Here all parts for this model:GV42LHDTV.

Regard.

Ginko.

When i turn the set on i get back lighting but no image or sound.


Fault at 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.

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

No wireless connection for laptop. Linksys router - model #wrt160n v2


you can run a direct line to that router and go to the cisco web site and get the information you need to run that router. its a pdf format and is 2.56 Meg. Try this

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It

lights up and will stay orange when the Router is powered on. The color orange indicates that

the Router is not using the SecureEasySetup feature, while the color white indicates that the

Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup

mode, the Cisco logo will turn white and start flashing. After the Router has generated

the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.

To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.

The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to

indicate a successful reset.NOTE: SecureEasySetup is a feature that makes

it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's

Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.

Power (Green) The Power LED lights up and will stay on while the Router is powered

on. When the Router goes through its selfdiagnostic mode during every boot-up, this

LED will flash. When the diagnostic is complete, the LED will be solidly lit.

DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will

remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when

the wireless feature is enabled. If the LED is flashing, the Router is actively sending or

receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.

Internet (Green) The Internet LED lights up when there is a connection made through the

Internet port. A flashing LED indicates network activity over the Internet port.

Good luck

My Vizio is plugged in to a good power spource but will not turn on. The orange vizio logo on the front panel is not lit. Has anyone else had this problem?


No standby light meaning that you have no power connect to TV, check voltage at your outlet. If it has, your TV need to check the power supply board inside.
