The screen is 55 inches and set up about 6 feet high (base) built in cabinet... I'm not sure where the lamp door is, or what the lamp door is, but no one could have opened it...where is it, what does it look like, and if it's closed, what other suggestions do you have?
Expert:  Edward replied 5 years ago.
The owner's manual for this TV can be viewed, printed or downloaded by clicking here. This is a large file and may take a few minutes to download and be viewable. Information on replacing the lamp and the lamp dooe starts on page 69 of this manual. These doors can at times just come loose. Heat is the enemy of electronics, and the 50V715 operates hot. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. The 50V715 are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

If you wish to repair it yourself what type of electronic training do you have?

What type of TV test equipment do you own?

Do you own and know how to operate an oscilloscope?

If you decide this is not something that you can do would you like an idea of what the cost to repair the TV will be?
