Question about Televison & Video

1 Answer

Hello, I have an LG 23" flat panel that will not turn on. I have a dish network remote that was working to turn tv on and off, but after a few hours it quit working. Now the tv has a red light and will not turn on or off manually or with remote. When using the remote, I had to plug and unplug the tv power to get the tv to turn on. Now nothing.

    Hi,
    Thanks for the response. Is there a way for me to replace the power supply board and where do I make the purchase. This was a refurbished tv with an out of date warranty. I don't want to spend more than I paid for it to put new power supply board in it.

Hello,

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

I wish you good luck.

    Hello,

    yes, its possible for you to replace the power supply board yourself. All you need to do is to remove the defective board and replace it with a new one. But make sure you take a picture of the power supply board before you disconnect the wires on it so that you can put the wires back to their appropriate places on the new board.

    Also, not the TV's store a lot of current. So you need to wait a while for the TV to cool before you touch anything on the board.

    For the power board part, visit http://www.shopjimmy.com/lg or click the "contact us" and order for the board directly.

    Take care.

How do I connect my LG TV to my dish network


Hello Al, my name is Cheri Torres and I work with DISH Network Internet Response Team. I came across your post and wanted to see if I could help. Connecting your LG TV to your DISH Network receiver should be fairly easy, depending on the connections you are using. If you are using an HDMI cable you will need to connect one side of it to your LG TV and the other end into your DISH receiver, as long as you have an HD receiver. If you do not have an HD receiver you are probably going to want to use composite cables(red, white and yellow). If you are using either of these cables you are going to have to set your TV to an input in order to receive the DISH picture. You can select an input by finding a button on the TV remote or the TV itself that is listed as input, source, AUX, mode or video. You will need to cycle through each one until you find the DISH picture on one of them. Once you have the picture you will need to press SAT on your DISH remote and everything should be working fine from there. I hope this information is useful and if you have further questions feel free to ask!

I am in need of the programming codes for a dish network remote control. Can you please help


Hello, my name is Becki, with DISH Network. We do not currently have the codes for your particular TV. But I have included some steps to do the Power Scan, which will scan your TV for the correct code. It can take a few minutes, but should help!

1. Hold down the Clear TV button until all lights at the top of the remote light up
2. Press the red TV POWER button
3. Press and release the up arrow on the remote about once a second until the tv turns off.
4. When it turns off, press the # (Pound) button
5. Try powering the tv on/off, and try the volume. If one or more of these functions do not work, start over at step 1 again.

Hello! Daniel Busa with Dish Network. That would be a case of remote interference. You'll need a model 6.3 or 6.4 remote. You can set it to a uhf frequency instead of an ir that will correct the issue.
