As with any electronic device, Pioneer televisions can be prone to problems due to extended use or manufacturing defects. Pioneer is a trusted brand in consumer electronics, and problems with their televisions are generally rare. However, it's wise to be equipped with some basic repair and troubleshooting knowledge in case an issue happens to arise.
Projection Television Problems
The most common problems experienced with Pioneer projection televisions are image integrity issues. These can occur in the form of misaligned colors, artificial geometrical effects, a dizzying three-dimensional effect or the inability to adjust colors via the convergence menu. These problems are usually due to faulty convergence chips in the television that may have deteriorated over time. Dropping the television or placing magnets near the screen can also cause convergence problems.
You can test for a convergence chip problem by pressing the "menu" button on your remote control. Find the convergence section of the menu and try adjusting the color setting up, down, left and right. If this doesn't change in the picture color, your convergence chips will need to be replaced.
LCD Television Problems
Screen integrity issues are more rare with LCD televisions. Rather, some users will experience other problems such as the television producing sound without a picture or not turning on at all. When your television isn't producing a picture, it's important to check the input settings on the television. Often, people will turn their television on without realizing that the current input is set to a powered-down input device, such as a DVD player or gaming system. If you're sure that the input is set correctly, reconnect all of the video cable connections on the back of the television, such as the HDMI cable.
If you're still unable to get a picture, try turning the television off for an extended period of time. The problem may be due to overheating or other factors that could be solved simply by letting the unit rest. A faulty power supply could also be the issue, in which case it will need to be replaced at a cost of $200 to $400. Even if your television works properly again after this resting period, the problem may reappear permanently in the future.
