Question about Sylvania LC420SS8 LCD TV

1 Answer

When my 42 inch sylvania is turned off. Model number LC420SS8, it makes a buzzing sound. I'm not sure it could be the tv because i have only had it for less than 3 months. When it is turned back on, it works fine, its only when it is turned off.

Green light flashes back red


These 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.http://electronicshelponline.blogspot.com/

I have a usb port and I want to watch nexflex can


Hi - No, that would not be how to set it up (It wouldn't work) You would plug a VGA cable like the one most likely plugged into your monitor (15 pin connector on each end) from your PC video card (this is with both machines powered off) into the VGA port which you have on the TV.
With the PC on turn on the TV and with the remote select your source (would be called VGA or PC) and there would be your PC display on the TV. Bring up your browser and login to Netflix. The sound would come through your PC speaker and you would be watching movies on your 42 inch display.
Enjoy, Mikeywaf

Need remote code for LC420SS8


SEARCHING FOR YOUR CODE
If your home entertainment device does not respond to the remote control after trying all of the codes listed for your brand, or if your brand is not listed at all, try searching for your code.
For example, after trying all of the codes for your TV, you still cannot get the remote control to operate your TV, then:
Turn on your TV.
On the remote control, press TV once. Then press and hold Setup until the key blinks twice, then release Setup.
Enter 9 - 9 - 1- 1. The TV key will blink twice.
Note: Substitute 1 with 0 if searching for a Cable code, 2 if searching for a DVD, VCR or PVR and 3 if searching for an Audio device.
Press Power and aim the remote control at the TV and press CH + one or more times until the TV turns off.
NOTE: In the search mode, the remote control will send IR codes from its library to the selected device, starting with the most popular code first.
Press Setup once to lock in the code. The TV key will blink twice.
To search for the codes of another device, repeat steps 1 to 5, but substitute the AUX key for the auxiliary device you are searching for.

Sylvania lc420ss8 lcd turned off wont turn back on


Simply unplug the set, let it sit for a minute or so, then plug it back in and turn it on. I had a similar problem with the same TV and it is working fine now.
