How to Troubleshoot a Philips TV Problem
Originally founded in 1891 as a light bulb company, Philips is now one of the largest electronics companies in the world. Their television division offers dozens of different sizes and styles across four different series.
While Philips is a quality brand, there is always the chance that your television will malfunction in some way. Fortunately, there are many resources that can help you solve those problems.
Troubleshoot your Philips TV problem with the instruction manual that comes with every television. If your problem has something to do with the way the TV is set up, you will find the answer in the manual.
Use online resources. Unfortunately, instruction manuals can easily be misplaced. Luckily, the Philips has online reproductions of manuals for each of their products, and searchable FAQ's. See Resources.
Call for help. If you would like to speak to someone at Philips, their general assistance phone number for TV's purchased prior to 2008 is (888) 744-5477. For televisions purchased in 2008 or later the number is (866) 771-4018.
Use a website called Just Answers that allows you to ask questions to licensed electricians via the Internet. You ask your question, and pay based on the success of the answer you receive. See Resources.
Check the set-up of your set. Problems frequently arise from the way the television is set up. If you are missing picture or sound, it can be a result of the television not set-up to display the correct signal. The sources can be managed with the television remote.
If this does not solve the problem, make sure the cables that connect the television to the signal are all connected to the right places. With a lot of use, cables can almost wiggle out of the socket. If they are not placed firmly in the socket, they will struggle to transmit the signal. The best way to do this is to unplug all the cables, and make sure each one is put back in the correct way.
Any problem that can not be fixed in one of these two ways likely involves a hardware malfunction. Most hardware issues should be handled by a professional.
Check for a design flaw. Probably the most common defect in Philips televisions is a design fault that causes the screen to malfunction when turned on. If you have soldering experience, you can take care of the problem yourself. The malfunction forces the screen to show only a white or grey background with horizontal lines on it. Shortly thereafter the screen will automatically turn off.
To fix this, open the back of the television and locate the CRT circuit board (picture tube). On the board, find R3340, a 10 ohm 1/3w resistor. If this is the problem, you will see the resistor has burnt open. Replace it with a 1/2w resistor, you will need a soldering pencil. this should solve the problem. You can find these resistors at any electronic store, they will cost you about a dollar for a pack of five.
