I Need a circuit board for my EDG 716R it came from the US and my daughter didn't about diferent voltage and pluged it in and it went pop.

Hi
I think your TV set has a short circuit in the RGB output circuit and shuts down or mute to protect the CRT. This circuit is located in small board attached to the CRt neck. If you are keen on electronics or you have a fried that is, you can mesure the voltages in the collectors of the three big transistor mounted on that board. The voltages of these transistor collectors are slightly diferent and the faulty one has low or even no voltage. It should be replaced.

P1409 - EGR Vacuum Regulator Solenoid Circuit Malfunction This test checks the electrical function of the EGRVR solenoid. The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range. The EGR system must be enabled for the test to be completed.

• EGRVR circuit open
• VPWR open to EGRVR solenoid
• EGRVR circuit short to VPWR or GND
• Damaged EGRVR solenoid
• Damaged PCM

The EGR vacuum regulator solenoid resistance is from 26 to 40 ohms.

it is toast,replace unit

Yep same happened to me, scared me, thought I had killed my wife\'s present, went and brought a 100VA (min power required) step down transformer convertor plug in type , still didn\'t work, has to be a fuse somewhere, no warranty on international purchase anyway so had a go at opening it up, undid all the screws took off the end part (near the needle) and still seemed hard to open, of course being a modern device it was clips, levered the cover off (from the back), undid four screws on circuit board found the glass fuse (thank god it wasn\'t some special surface mount thermal type etc) had a box of different fuses and looked it was the small 2A 250V glass type so swapped it out, put it back together and tada! Fixed!

( "Power Supply Problem Not Switching "???? )

How do you know it's Not Switching? Do you mean the TV wont turn on when you push the power button on and off on the TV and also with the remote control unit? Is that what you mean? If YES! Then, If your Vizio TV wont turn on and has NO-PICTURE, NO-SOUND and a BLACK SCREEN, Then the TV has an AC or a DC Voltage Problem.

1 - First, check the wall outlet socket by pluging in a lamp to see if you have 110 AC-volts there. If the lamp works, the wall outlet is OK! That means the problem is inside the TV.

2 - Before, you remove the back off the TV. I want to *(CAUTION - YOU)* The Power Voltages inside your TV are Very, DANGEROUS!!! There is 110 AC Volts at a 20-AMP-Rating ***CAN BE A LETHEL DEADLY SHOCK HAZARD to HUMANS!!!*** Also there are DC Voltages ranging from 3.3 to 24 volts. And R-F- VERY-HIGH-VOLTAGE of 20,000 Volts or More.

3 - You will need hand tools and a Digitle Volt Ohm Meter to check AC & DC Voltages and the OHMS Meter section to check resistors, capacitors, coils, grounds and contacts.

4 - With the Back removed, and no-power to the set. Inspect the power board for any signs of BURNED, LOOSE or BROCKEN parts like resistors, capacitors, coils, fuses on all boards. If you discover damaged parts, make a list of them. Then you must deside if you are qualified to do the on board repair or just order a new replacment board.

5 - If on the other hand you didn't discover any damaged parts by your inspection, It's time to put the Meter to good use. Plug the TV power cord to the wall outlet. Set the Meter for AC - voltage range of 200 or more. check for 110 AC volts going to the power supply board fused inputs.
If NO replace the cord. If YES, look on the board for voltage test points marked on the board. (SAMPLE!) 3.3 vdc, 5 vdc, 12 vdc, 24 vdc, and so on. Set Meter for DC Volts now, range 50 to 100. Put the black lead to ground and the RED lead to each test point marked on the board while repetetedly pressing the TV power on & off button..

6 - If ANY of the DC voltages were LOW, WRONG or MISSING, The Main power board is defective and needs to be removed and replaced with a new one. Write down the board number that is on the board and use that number to order the new one. You can order it on the Net!

*****(NOTE)***** If you are not an electronics tech. don't try to fix the old defective board... but, keep it handy, you might need it for parts later. :-)

Hope This helped... GOOD LUCK! NOW, GO FIX YOUR TV!

The over-the-range will need to be taken down, unplug and remove the top, look to the right keypad facing you, follow wire from the control board mounted on back of the keypad to a circuit board, look for a silver rectangular high voltage capacitor and short out the two points, near by you should see a small fuse clipped in. Pop it out and replace with the same current rating, if fuse blows again check the door switches, usually one or two are faulty.

Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint.

Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.

If you are not, don't work on your TV. It will be your sole responsibility.

Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good.

Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.

And REMEMBER, you can kill yourself when you work on TVs.

What network do you use in your phone? No one will give you LG GW300 unlock code if you didn't mention your network. Just for your information diferent network has diferent LG unlock code and you can get that PUK from your network provider, call them and they will give you that code.

Hi
The power supply regulator board inside your TV is fauty. The 'pop' sound you heard will be due to capacitor breakege. In the power supply board, there are large filter capacitors, to smooh the rectifed AC voltage. If there is any rise in AC voltage, above the normal voltage capacity of the fulter capcitors, it will burst ofr, or get leaked with a 'pop' sound. You have to open your tV to view this. Look at the power regulator board, which can be easly located, as power chord goes direltly to it after a filter circuit. It will have three or more large bulky capacitors, and these are the main filter capacitors. Repairing this board must be done with care, as this is a dangerous board to touch because most of the components in this board will be live and touch it will be fatal. In most cases it will be best to replace the board as a card basis. OK
