    I was thinking if I follow my 120 volt plug into the back of my LCD—I thought this is or would be where the inverter would be. I know what a connector is I am talking of the actual entire board. Please explain and thanks for the help.

    Just a note I have 3 sections of boards in the back of my LCD—1-- Where my 120volt power feed, 2-middle of screen, and then 1 more. Which are you speaking of the middle board—any scene shot?

Hi,

No, that is just the connector. The inverter board is inside the LCD on an elongated printed circuit board. Its input would be pure DC as opposed to AC from the 120 mains. Its function is to produce high frequency/high voltage to supply the Cold Cathode Florescent Lamp(s) which provide the backlight illumination of the LCD panel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,

    My compliments that you have gone as far as checking the inside of the monitor.

    Chances are the board where the 120 leads to would be the power supply board.

    Most inverters are elongated printed circuit boards with small transformers for the high freq/high voltage. Below are images of inverters.


    To my understanding, a most Gateway models uses either an LG708G or an LG708K. The inverter itself was manufactured by Ambit with part# 6633TZA013A.

    Hope this be of additional help.

    Many components or LCD monitors are available on line. The easiest would be to do a Google for "LCD parts"

    Incidentally, the previously posted images were adapted from lcdparts.com

What could be my problems if my battery was week but when I jump start it on my rv the lights worked but the 120 volt wouldn't


the 120 volt works of an inverter that takes a strong battery for it to work
jump starting is only 12 volts and that is expanded to 120 volts by the inverter
jump starting could also damaged the inverter with a power surge from connecting and disconnecting the jumper battery
Fit a new battery or have the old one load tested to ensure that the battery is failing
have the inverter tested for operation
could be a simple fuse in the inverter

How to connect the power to the dryer


most likely 240volts as most 120 volt dryers are already wired,depending on if its a 3 or 4 wire system depending on local electrical codes,but if its a 3 wire cord,take the RED to terminal L1 and Black to L2 terminal on the dryer terminal board HINT:(the RED and Black can go on either L1 or L2 they are interchangable) ,then the White wire to the N neutral terminal on the dryer terminal board usuall between the L1 and L2 terminal,if theres a Green Wire on the cord this is safety ground and can be attached to any metallic part on the dryer,if its a gray flat cord the 2 outside wires are L1 and L2 the center is Neutral,
so its:
RED=L1 or L2
BLACK=L1 or L2
WHITE=N or Neutral
GREEN=Safety Ground the metal dryer frame

Where is My Philips 32pfl3505d f7 LCD TV fuses


I assume you are referring to the ac fuse, it is located on the power supply board. Just follow the ac power cord and it should lead you to it. If your set doesn't have a built in power cord, the fuse will be next to the power cord connector.

Power connector pinout for CT-13R50 television


Directly from the user manual, Page 5 under "AC/DC Power Sources":
DC Models ONLY
"This TV model operates on both standard household current (120 volt, 60 Hz AC) and car battery (12 volt negative ground DC) through the cigarette lighter. An AC power cord and a car cigarette lighter adapter cord are supplied.
Household Installation
Insert the AC power cord into the connection on the rear of the TV. Connect the two pronged plug into an AC outlet (120 volt, 60Hz). If you are unable to insert the plug fully into the wall outlet, try reversing it. If the plug does not fit, contact an electrician. Do not force the plug or defeat the safety purpose of the polarized plug."

The manual goes on to describe the vehicle installation which is identical to the household, with the only difference being the car plug goes into the DC side of the power connections at the back.

There are several kinds of power cord available for older TV models. Unfortunately, after an exhaustive search, I was not able to locate a photo of the back of that model television.
However, I have included three of the typical US power connectors found on a great many devices and in the majority of cases, one of these cords will likely be the one you need. They can be found at most local stores such as Wal-Mart, or can be ordered online from Amazon. Also, the cored generally only fit in one direction, especially if the cord happens to be polarized (thin blade and wide blade).

I hope this helps!

T101r just installed by licensed electrician. On off switch does not operate. Power is continuously supplied to timer. On Off pins do not operate. I must control power from gfi attached to house or breaker...


I have this timer. The clock should run continuously in order to keep time.
The ON/OFF switch should turn the load (lights, pump, etc.) on and off.
If it doesn't, either the device is defective or it is incorrectly wired.
The wiring should be:
The 120 volt supply white wire connects to the A terminal.
The 120 volt supply black wire connects to the LINE terminal.
The load white connects to the A terminal.
The load black connects to the LOAD terminal.
The clock wires area already connected to the A and LINE terminals.
Let me know what you find.

First, I'm confused about your dryer cord change. The green ground wire should NOT be connected to the neutral terminal block - but rather stay connected to the dryer cabinet. Here's a detailed link the describes (with photos) how to change a dryer's 3 wire cord to a 4 wire cord. This work should be double-checked to make sure you've done it correctly and have a safe installation.

Since you're not getting the dryer to run (you didn't say if it spins but has no heat or if nothing works at all) and you've checked the components of the dryer; the only thing left is to make sure there is 240 volts at the dryer outlet.

Make sure the power is ON. You should have either a 2 pole 30 amp circuit breaker or two 30 amp fuses that provide power to this outlet. Make sure the fuses are good / circuit breaker is ON (not tripped).

Do not touch a metal probe at any time that one is connected to the outlet in the steps below.

With a meter set to 250 volts or higher range - or a wiggy tester, slip each of the probes into one of the two straight blade openings in the outlet (use of a test lamp is discouraged as there is not voltage reading provided - it should only be used to indicate the presence of power). You should have a 240 volt indication (an indication of anywhere between 220 and 250 volts is acceptable).

Remove one of the probes and press it into the ""L" shaped opening; leaving the other probe in the straight blade opening. A 120 volt indication should be present (an indication of anywhere between 110 and 125 volts is acceptable for this and the following 120 volt measurements).

Remove the probe from the "L" shaped opening and press into the "O" shaped opening. Again, 120 volts should be indicated.

With the probe kept in the "O" shaped opening, remove the other probe from the straight blade opening and insert into the other straight blade opening. A 120 volt indication should be present.

Remove the probe from the "O" shaped opening and press into the "L" shaped opening. Again, a 120 volt indication should be present.

Remove the probe from the straight blade opening and press into the "O" opening. There should be a zero volt indication. A value of one or two volts is acceptable - but zero is expected.

If you get results that deviate in any way from those listed above, there is a problem with the circuit. An electrician should be called if the circuit breaker can't be reset or if fuses blow. If the voltages are indicating correctly but dryer still won't operate, there may be an issue with cord wiring or internal controls or safety devices inside the dryer.

I hope this helps. Please rate this reply - thanks!

T103 clock not working


Please read all of this post. You may burn up the 120 volt T103 timer motor is you are not careful.

The statement: "I have 120v board with 120 constant and 240 timed" is not very clear to me as to what you mean.

In US residential wiring, the white wire is not always the "neutral;" The white wire is sometimes used for 240 volt circuits.

We cannot tell you how to wire your timer unless we know _exactly_ what you have.

If your incoming supply cable (from the breaker box) has 3 wires (black, white, and bare), there are two scenarios:

1...If the voltage from black (hot) to white (ALSO hot in this case) is 240 volts, and you have only 3 wires (black, white, and bare), then the T103 is the _wrong_ timer if you are trying to control a 240 volt load. You should use a T104 timer.

The T104 uses a 240 volt timer motor and the T103 uses a 120 volt timer motor.

2...If the voltage between black and white is 120 volts, then you will only be able to control 120 volt loads; then the incoming black supply wire is connected to terminal 3 and the white (neutral) wire is connected to the "A" terminal. The bare equipment grounding wire is then connected to the "GR" terminal.

To show the difference, if you are trying to control a 240 volt load, to use a T103 and wire it _correctly_, you would need to have a incoming supply cable with a total of 4 wires (black, red, white (neutral), and bare) Black to red would be 240 volts. Black to white would be 120 volts. Red to white would be 120 volts.
The connections would be as follows:
White (neutral in this case) to the "A" terminal
Black to terminal 1
Red to terminal 3
The 240 volt load would then connect to terminals 2 and 4
Both the bare equipment grounding wires are connected to the "GR" terminal.

Since you did not mention a red wire, I can only ASSUME that this is not the case.

Sorry, we can't tell you how to wire this timer based upon assumptions.

So, what do you have?

Hi, I live in Argentina and I have a kenmore 96093800 Dryer. This Machine has 120/240v and his plug has 4 pins. Two pins are flat, one pin is cilindric, and the fourth pin is en angule. How can I connect...


Are you connecting this Dryer cord to the Dryer or are you looking for a wall plug with this same configuration to plug into. This is a standard double ground configuration and you can buy the wall receptacle at a hardware store. Your house should have 4 wires to this, 2 lines, a neutral, and a ground. As always the recommendation is that you have an electrician install your house receptacle. Your Dryer power cord is something you can install however. The two outside terminals on your dryer 240 volt wiring block are connected to the two outside wires on your power cord. It does not matter which wire goes to which side. Your two inside wires on the power cord are connected like this. One to the middle terminal on your 240 volt dryer terminal block and one is connected to the dryer case itself. Again it does not matter which wire goes to which ground. Make sure all of your connections are tight, as loose terminals eventually burn up. Do Not plug in your dryer power cord until everything is hooked up tight. I actually had a customer plug in his cord and then try to connect the wires to the dryer. The wires arced together and blew the terminals into molten metal which burned this customers hands and face. Do not do and electical repair unless you know what you are doing. On your cord the two straight terminals are line terminals, the round and L shaped terminals are grounds or neutrals. Good Luck, Appliance Specialists

Clock doesn't work


The wiring diagram for that timer is somewhat misleading. The 120 volt clock timer motor is connected internally to the "A" (neutral) terminal and the #3 terminal. The "A" (neutral) terminal is to the immediate left of the #1 terminal.
Here's how to do the wiring for your use, (assuming a 120 volt supply circuit and a 120 volt lighting or other load):
Connect the incoming power (line) black wire to terminal # 3. Connect the incoming (neutral) white wire to terminal "A".
Connect the outgoing (load) black wire to terminal # 4.
Connect the outgoing (neutral) white wire to terminal "A".
