Philips is a trusted name in consumer televisions, and their products are known for their reliability and excellent performance. However, as with any electronic device, Philips televisions can be susceptible to problems over time, due to the fault of the consumer or via manufacturing defects. Whether you own a projection television or a new flat-panel model, these repair tips should get your TV running in top performance once again.
Flat-Panel Issues
One of the most common issues owners of flat-panel televisions experience is a set that will turn on and produce sound without a picture. Often, this is due to the TV's settings. Using your remote control, change the input settings to a variety of devices. If the selected input corresponds to a gaming console or video player, be sure that the external unit is powered on and is producing video. Some DVD players will have an audio-only mode, so be sure to deselect that option.
If doing this doesn't produce a result, check the TV's cabling. HDMI and S-Video cables can become loose over time, or accidentally pulled out. Chances are good that the audio cable will still be seated while the video cable may have come loose. Disconnect all cables and reseat them firmly. It's possible that the cables themselves have deteriorated, so try swapping in other cables before you decide the problem is stemming from the TV.
The problem may be that your TV's power supply has gone dead. This is a repair that you'll likely be unable to perform yourself. If the television is still within its warranty, contact the point of sale and ask for a repair or replacement. Otherwise, contact a local authorized repair shop.
Projection Issues
Although flat-panel televisions currently dominate the market, you may own a projection television. The most common problem with these types of sets is a convergence chip failure. This will present itself as image distortion, such as incorrect colors, blurring or a blue arc on the screen. Test your convergence chips by going into your Menu settings and adjusting the colors. If the colors can't be made accurate, or if they can't be adjusted at all, you'll have to replace the convergence chips. The cost of this repair will depend on your particular Philips television. Convergence chips for older sets may be out of stock and need to be back ordered.
