    hi i have just been reading about viewsonic monitors and tv's and found out that they have an inherrant fault on the power supply system apparently they blow a capasitor on the power system and that renders the full power to the tv u/s there is not a quick fix to this tv, but most of the people who had them were just getting rid of the tv and getting a different tv instead, some however have attempted to fix the fault with a new capasitor with vairied resaults, here is a clip from the forum i follows:

    Alright the answer to your first question is it is 2x(2n4401). I ordered surface mount 2n3904 npn to take its place and I will have the parts tomorrow oct 2,2007 to test this P/S. So I will let you know the results asap. The answer to your second question is the + end of c33 will face the (c7) cap. Please feel free to email me at so we can work together on a solution. I did call up edwards repair for viewsonic and got a whole mess of schematics but something just doesn't match up . Let me know if you want a copy of them because maybe I am overlooking something you might be able to shed some light on. Please Email me because I dont check this forum that often.

    Well I got the parts in and after replacing q7 transistor,c33,and the rest of the swolen caps.That TV WORKS GREAT!!! So if anyone has a N3260w Viewsonic 99% of the time it is the power supply and the above componets. Please email me for any questions

    as you can see some people are repaing them with some success...hope this helps

Philips htl2100/12 soundbar doesnt respond to remote control after plugging in

My soundbar won't power up. So I pull the battery out of remote, press a few buttons, put the battery back in and all of a sudden the device can be powered up and controlled. Until next time it stops responding. I replaced that original battery with a new one but the problem still persists.

TV will not turn on and stay on when turned on. I have a ViewSonic 4060w LCD TV Is there a battery on the TV that needs to be replaced? I have unplugged and repluggehald TV. What can I do? I have to...

iF THE SET is a year or even two old and you have to repeatedly turn it on and on but once it is on it is ok, the problem is in the set's power supply.

All of these sets (every brand) have a "standby Power supply" built into them, it runs 7/24 even if the set is not turned on. One of the areas some companies cut corners on is the filter capacitors in this part of the set: Say the constant voltage is 9 volts and they use 10 volt rated caps, the caps will fail after a year or two from heat.

The reason companies do this is the cost difference say on 10,000 sets between 10 volt versus 16 volt rated caps is a nice piece of money.

If someone opens it and follows the power cord to the supply it will be easy to see, these caps (see photo) have a perfectly flat silver top with creases---any caps puffed up are bad.

Look at the caps and Before you rate this information let me know what you find, this problem will not just go away and usually gets worse and worse until the unit will not turn on at all.

ViewSonic LiteBird PJ875

If you haven't tried it already, unplug the unit, hold down the power button for 15 seconds, release, then wait about a half hour and try plugging the machine in and powering up again. This may reset the memory and enable your projector to start up normally.

I cant convert my 24" ViewSonic remote to my Comcast remote

Try and re-do your codes for your remote. If you don't have the codes try this.
Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.

Viewsonic model vs10846-1m aka N4060W won't turn on.

I found if you hold the power button down on the remote or the tv , hold it down for anywhere from 2-5 minutes the green light will blink and blink and blink, all of the sudden it will stay on. then shut off, but if you turn it back on on the light will again stay on , do this 3-4 times and then the tv will turn on. Once you turn it off for over 10 minutes you will have to go through the whole rigamaroo again. This will only work for a while, mine has quit completely now. The Veiwsonic guy gave me a part number for a power board he said was most liley the issue. It ran about $71. I've got a repairman coming tomorrow to see what the dealio is. I'll let you know what he tells me, good luck!

Viewsonic n3251w will no longer display Closed Captions

You can reset your viewsonic remote control by removing the batteries, and holding the power button down for 10 seconds. Just 10 minutes ago I repaired my remote, which was doing absolutely nothing, not even turning the set off and on, Called Viewsonic, they told me this, and it worked ! Yay !

When you turned off the Wii, did the light turn red or amber?
If you haven't done this already, hold the power button until it shuts off, and the light is red. Power it back up and try your remote again.
