How do you change your tv from pal 50 to pal 60?

PAL 50 and PAL 60 are signal standards rather than a television specification. PAL is the color encoding system used in Europe and other parts of the world. PAL is usually run at 50 fields per second hence the term PAL 50. North America uses NTSC as the color encoding standard and is normally used with 60 fields per second.
To view NTSC content on a PAL television, the color encoding needs to be converted from NTSC to PAL. There are a number of converters that do this job well and at a relatively low cost. However, converting 60 fields per second to 50 fields per second demands much more processing power. Broadcast companies will pay up to $60,000 or more for a standards converter that does the job well. Because of this, many NTSC to PAL converters will change the color encoding but leave the field rate the same and output a PAL 60 signal.

Many PAL televisions will handle a 60Hz signal but some won't. It is a feature of the television and one that cannot be added at a later date. Many modern European televisions will also now handle NTSC signals in their native form so if a PAL 60 signal doesn't work, it might be worth trying an NTSC signal without any conversion. Unfortunately, if neither work, the only options are to obtain a full standards converter or a television that will handle multiple standards.

It is worth mentioning that North American DVDs have a region code. As well as running in 60Hz, the code may prevent the disc being played on European DVD players which have a different region code. Before investing in new hardware, make sure that the source material isn't being blocked by region code restrictions.
