Question about ViewSonic VA720 17" LCD Flat Panel Monitor

It won't stay on. It blinks on, then the screen turns off but it says its still on. So I turn it off, then turn it on again, and it does this exact same thing. It does this for a really long until finally it just stays on. What do i do?

Hello,

Your power supply is having a problem starting up. This is a common problem on LCD monitorsit won't stay on. It blinks on, then the screen - 2.gif after 2-3 years of use. The heat build up in the case causes parts in the power supply called capacitors to blow out and short out the unit. If you can solder then you should be able to fix it yourself. Go to our web site at:
www.ccl-la.com/badcaps.htm and look at the pictures of what the caps look like when they blow out. Open the back of your monitor and replace all of the ones that look like the pictures and you should be back with a working monitor. The values you need to purchase will be marked on the sides of the blown caps that you take out. Be sure to get low ESR and high temp 105c replacements or you will be back doing the repair again in a month or two. The capacitors from Radio Shack will not work.. The replacements can be ordered from several places on the internet or we can supply them for you. When you install the replacements be sure to insert them with the polarity stripe on the side going the same direction as the old ones when going. If you don't want to do the repair yourself we do offer a repair service for $30 plus return shipping.

I hope this helps, If so please rate our solution.

JVC LT46J300 Blue Light blinking TV won't come on all of a sudden


These blinks to standby light are fault indications, called blinking codes. From the number of blinks occur at one time switch on, you can get an idea about the faulty circuit stage inside it. Count it. Visit this site. It has details about blinking codes to many brand televisions.http://electronicshelponline.blogspot.com/Pull up older posts there, either by its left side bar, or see it in Timslide option

Monitor won't turn on after a few hours of being shut off


If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.

My WD-60639 DLP TV won't stay on (it goes off right after it gets on)


You should be getting a light or lights on set blinking in this case, and the set should have a self check if they blink etc---hold menu and input in at same time for more than five seconds and release both, the blinks on the power light should be a two digit code like three blinks, seven blinks which is 37 Let me know what if any code you find.

If you unplugged the set during this time it will clear the errors so you have to try to turn it on again, let it fail and do the check again.

Sony won't turn on


Hi,

Please let me know the exact model no. of your TV to accurately diagnose where the fault came from. Also, please check what is the status of the LED at the front panel, does it has a steady, blinking light, if blinking, please count how many times it will flash. Some of the blinking LED denoting an error code.
