I have an old onyx tv which doesn't have a remote, I found a old universal remote I had lying around but it didn't have instructions, so I need a code to program it...could anybody help me please?

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. One among it has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.
Search the site by type in the brand name of your device, in the "Search box at the top right of the Home page display" to see the set-up codes to your device, with different brand remote controls.

Please go to, enter the tv repair forum, then you will see a feb. 2nd post by krjandsue regarding a soyo tv. open that post for a detailed explanation of the problem, including pics....

Good day!!!

Sorry for the late response because my internet connections got problem hope you understand..

OK,First thing I need to know if the board on the picture in the forum is the original board of your TV or it is the board you purchase..

If that is the board you purchase I think that board is the exact replacement however it different on the version of said that the TV works fine but the remote is not function..Or the IR is bad..

try to see the version on the original board to the new purchase board if the same..

check the encircle part of main board need to compare..


If they are the same the problem I see is the IR sensor try to clean it first including the glass protector before you replace it..

But if the problem is different version no choice you need to replace the board or contact the store where you buy it and ask for replacement..

Just keep on touch to fix the problem..

Hope it helps
thank you

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.
Search the site by type in this key phrase "how to test a remote control "in the "search box at the top right of the display window of the Homepage" to get the related post quickly. [open and clean] [open and clean]

Will not turn on

Off brand televisions have problems with the engineering behind their components. You will need to look for popped or buldged capacitors on the power supply mainly! Also look for any burnt resistors as these also over heat and will pop capacitors.
