Question about ViewSonic VX924 19" LCD Monitor

2 Answers

DELL P1130 I posted this a while back and got some good feedback but am stuck again. The G2 voltage is 630V, way higher than the 400V it should be. I have a schematic but can't figure out which resistors would affect (drop) this voltage. Thanks. dewberrp

    I replaced the pot, even tried substituting ones with more and less resistance. No avail!. There should be a high voltage resistor or resistors which control the front panel controls for brightness and contrast. I fixed a similar monitor by dropping this resistance from 10Meg Ohm to 6 Meg Ohm. However I can't seem to find the corresponding resistors in this model.

Usually the screen control potentiometer cause this type of problem, you can check the screen control is working properly.If not you have to replace the flyback transformer.

Wall charger replacemnt

Go to and search "Trio Stealth G2 charger"

or, if you can't wait

check the OUTPUT voltage and amperage on the old charger (for example, it could say: "5.0 VDC --- 1000 mA" (that means 5 volts, 1000 milliAmp), and find a standard charger with same voltage, and same or higher amperage.

Black screen, sound ok.flyback lines when G2 turned up

Never tune G2 voltage too up to a state, to appear retrace lines on screen. it is bad. It might make the CRT damaged. Check the video output card, and the voltages comes to it. This card can be located at the neck of the picture tube itself, will directly plugged to its back of the neck. Reduce the G2 voltage, in such a way that, there is no retrace lines appear. Be careful. To get some details, Pull up older posts

When i turn my p1130 on the green light comes on and in about 15 seconds it start flashing orange?? and wont come on , please help .

The high voltage transformer is loading down the monitor, the cost to repair can not be justified, I recommend a replacement.

Monitor comes on then goes black

I've got a couple of these monitors that have the same problem. All the caps in the P/S except the large inverter filter (110uf/400v) are bulged. I;ve ordered all the caps - INCLUDING the one that doesn't look bad since all have been subjected to the same high heat (or are bad caps in the first place {Non standard?} so am attempting to prevent a recurring problem. Since all of them cost around $6 TOTAL (plus s/h) there's absolutely NO reason not to replace all of them. The ones in my monitors are: 1-22uf/50v, 1-100uf/400v, 1-470uf/10v,2-1000uf/10v and 3- 470uf/25v. I opted for the slightly higher voltages available when I ordered since that also helps and there's plenty of room. the 10v caps will be replaced by 16v ones, the 25v by 35v while the 50v & 400v will be the same voltage. Hope this helps somebody. Good luck and solder quick to keep the heat down.

What is the maximum amount of electrical energy that can be delivered durning a short circuit for low voltage 230v/400v

Tom, Not sure if what you're asking relates to the Maximum electrical energy (Voltage and Amps) that can occur during a short circuit through a properly protected electrical circuit (protected by a circuit breaker, etc.) or if the question is for the maximum amount you could potentially get from a short circuit on a 230V or 400V electrical line to ground OR another electrical line/supply.

IF the circuit is a 230V-AC circuit protected by a double circuit breaker, you could see the entire Voltage (230V-AC) and up to the full Ampere rating of the circuit breaker, (20, 30, 40, 50, etc Amps) during a short circuit condition to Ground.

IF the circuit is a 400V-AC circuit protected by a double circuit breaker, you, again, could get the entire Voltage (400V-AC) and up to the full Ampere rating of the circuit breaker protecting the circuit, when shorted to Ground.

Now, IF the short condition involves one of the above line voltages AND you are having it shorted against another Voltage/Amp circuit, the total potential Voltage and Amps you could experience, would basically be the sum of the two Voltages (and Amps) of the two (2) circuits being put into a short condition. So you would/could see a potential short circuit of whatever voltage is available, depending on what and where the short circuit is occurring.

By way of example, I've seen a 240V-AC 60 Amp circuit shorted to another 240V-AC 60 Amp circuit and the resultant "short condition caused enough damage, due to the voltage and Amps provided, to melt and weld the machinery's electrical connections, rendering the unit a total loss, not to mention that the person that caused the short to occur, received a face-full of melted copper metal bits all over their face and body. Thankfully they were wearing safety glasses, and their eyesight was saved, albeit, with some temporary blindness caused by the extremely bright flash and explosion.

The examples provided assume a properly working/functioning circuit breaker protection. However, if the circuit breakers are faulty, it is possible to recieve much higher vlotages and Amps, since there would be no protective circuit breaker that could trip the power off. In that case, the Main circuit breaker becomes the fail-safe protective device and that could have a much higher Amp rating, thus the maximum Voltage/Amps would be limited by the Main electrical ciruit breaker and electrical supply available at the location where the short circuit occurs.

This could be MUCH higher Voltage and extremely high Amps, depending on the situation and equipment involved.

If you have more information about the particular situation, please post a follow-up comment and I'll provide you with some more info.

I hope you find this Very Helpful and best regards!

Too Bright P1130

Dell P1130 Service Manual r + g + b resistors measure on them and chassis -ground by have a black picture for getting the highest voltages if its looks like out of range look the manual and the resistors on there values that the ones and values you write about can be made of the only few carbon composite resistors witch can have get some drift over time over the tolerance. this kind of dark brown resistors are very sensitive for moisture and more, best is to soldering one leg of the resistor out and measure for compare on every resistor its resist or disconnect the crt print from the tube and if the resistors are good then reduce on the potential meter on the line transformer some reduce brightness below if its so bright that its against the backlashes. control focusing also after that . i have only suggest by this chassis its a 25 years ago i was very busy with c r t t v and video and more a little study on the manual can give you other results for some deformed capacitors also why its come out of range begin with the power supply and don,t forget to disconnect before measuring the power supply the horizontal line load to the line transistor (fly back because of your multi meter and have a 100 w lamp in serial in mains to control for your power supply on .
