Monitor started to flicker then went blank

Screen is blank, power light is blinking green. Disconnecting the video connection makes no difference. A substitute monitor works OK, so definitely seems to be a monitor problem. Any ideas? Many thanks.

Re: monitor started to flicker then went blank

I have a envision professional series and I love it, but I will get to the point.
I recent ly received a Envision EN9410e monitor, had the same problem (flickering screen then turned on, then off then on then blank). The problem is bad capacitors. There are 7 electrolytic capXon capacitors that will need to be replaced. You should see if the caps are bulging or leaking, if so replace. As known by many replace with the same capacitance and voltage. There are a few incidences that the capacitors where replaced and the problem wasn’t solved; this is because the cap problem wasn’t taken care of and damage occurred to another part of the monitor. The back light is a Royer oscillator (cool things) and it uses two smd mosfet transistors. They are on the green side of the circuit board near a big control chip (they each look like a off rectangle black square with eight pins) you need to see if there is any carbon or chard residue between the pins or burning smell from them, if there is you need to remove the transistor and do some board repair then ether put a new transistor or try the old one. No offence to the people at Envision but not smart putting the drain, gate and source so close to each other under the chip where there is such high voltage! Hope this helps.

Re: monitor started to flicker then went blank

I have the same problem with my monitor. It started a few days ago and Christmas day it was done. So now it just keeps turning itself off and on.

I have had problems connecting to internet all weekend (internet - red light), am on now but internet and ethernet green light keep blinking, is this ok.

No because dsl light should be solid green light. You need to contact your ISP to check if there is a problem on the network.

My DSL 2wire modem always blink like crazy.

DSL light blinking green/red indicates you do not have a solid connection to your DSL signal. Typically this can be anything from the connections at your home all the way to the connections with your ISP. As I do tech support for this model of 2wire modem all day long here is what I would tell you to do if you were calling me:

Are you using the proper length of phone cord (15ft or less): people sometimes have a longer phone cord in use and while it MAY work for a while outside conditions will effect the DSL signal enough that it no longer cuts the mustard. The longer the phone cord the more resistance a signal has in reaching the modem.

Filters: Typically the 2wire modem comes with 3 1-way filters and a single 2-way filter. Often people put the wrong filter on the modem, which doesn't even require one, or they put the correct filter (2-way filter) but hook it up to the wrong end (that is to say it should be connected to the DSL side of the filter). All other devices in the house such as phones, fax machines, Tivos, DVRs, Sat TVs, and monitored alarm systems (AKA anything ELSE connecting to/using the phone system) should be on filters.

Phone service: Do you have phone service? Do you have a dial tone or static? If so all problems with phone service will effect your DSL service as that is how the DSL service is piped into your home...that is to say through the phone line. Do not contact your ISP for this problem as it is a phone line problem creating your internet problem.

Phone jack location: Have you tried moving the modem, it's power cord, and proper length phone cord to another jack? Granted the argument that "it worked yesterday, so it should work today" is a strong one but sometimes putting the modem on another jack JUST to test out any potential wiring problems is a helpful one and could save you a lot of frustration. If one jack gives you red/green DSL lights and the other gives you solid green...that should speak for itself.

ISP provider: IS your service turned on? It may be a shall we say....obvious but if your service has been turned off, or not even turned on yet, then that would be why. In addition, if the above does not help in determining what the problem is, a technician may need to be dispatched to determine where the fault lies. Sometimes it's the box down the road and sometimes it's a few miles away.

Red Internet Light on Westell model 6100F

hi rtoffler....

by the way, is the dsl light solid green or red???...and if it's red... the line connection from the server to your modem is doing good...however, you said that the internet light is red because you have not configured your modem properly.... i mean, you need to update the interface of your modem before you can go online....and whether the message said that you're connected to the network when you connect your XBox 360...the only assurance is when you can browse different websites and lets you go online...however, your pc should be in tri core so that it's compatible with your Xox 360 video game,kkk and so that you would not encounter problems and errors in the future,kkk....and by the way...the data light is always blinking esp if you're browsing websites, the faster it'll blink nd it can't go on a solid green light anyways...,,kkk....and i do hope i was able to configure a little to your concern now....and enjoy playing and downloading more and chanllenging and fun games with your Xbox 360k,,,,happy playing games, rtoffler!!!!! and happy new year by the way!!!!...:-D

4100 Light flash no connection

*if the DSL light on your modem is blinking..
TRY: using different filters// check physical connection
IF: not resolved call ISP for a trouble ticket for their line department
*if all the lights constantly blinks
DO: purchase new modem, maybe deffective already or check if modem still under warranty so provider can replace it

NOTE: plug 4100 modem directly to the back of the computer tower without the linksys router and check if light status still the same...
HOW: cable connected from back of modem shud be plug in directly to port at the back of PC tower.. completly remove linksys and turn linksys off..

Your modem is not synching. It could be a number of possibilities, and you're going to have to do some troubleshooting to narrow it down.
  • Verify that your AC, Cat 5, & ethernet cables are connected securly
  • Verify that your modem is not in "standby" mode
  • Power cycle your modem
  • Try a different cable outlet
  • Call your ISP to make sure your modem is provisioned and your service is set up for cable internet.
