Televison & Video - Recent Questions, Troubleshooting & Support


The idea is that you buy the board complete. You are looking at the wrong side of the board. The components are on the other side. Look for the component symbol for a fuse, but how do you know there is one? See below a cautionary tale I wrote a while back.

Here is a question that we see often.

Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?


So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour.

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. The site has set-up code list & set-up procedure to many popular brand remote controls. The site 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. Set-up code list to many brand remote controls also is given. 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.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window" to get gathered related posts. ..

A component on one of the boards has failed. If it is an antique rear projection television, the bulb is about to fail, just replace it. For anything else, Take it to a repairer.

The most possible scenario is that there is a dry joint somewhere between the video input female rca connector and the tv board's main signal processor, and a technician's assistance would be a good solution for the problem. Attached here below is a link to your tv model operation manual download. Please go through it and see if it works, if it fails, consider changing the entire main board.
