makd511,

On my mp5, there is no physical button to switch to TV-Out. Instead, the TV-Out function is setup by the settings in the Toolbox Menu ( ie System settings) that I described in my previous posting, and you must use the TV-Out cable with the 4 conductor mini-plug, which is inserted into the mp5 player's earphone jack.

There could very well be sellers, that falsely claim a TV-Out function. In that case, I guess you would have to carefully open the mp5 player, and examine the chips. My mp5 player has a Chrontel TV Encoder chip (CH7024B-DF) for the TV-Out function.
here is a link for the datasheet... http://www.chrontel.com/pdf/7023-7024ad.pdf

Here is a pic of the board layout of my mp5 player.

There are 7 chips in this mp5 player.

TV Encoder: Chrontel CH7024B-DF
CPU: Ingenic JZ4725
Flash memory: two 4GB chips (Samsung K9LBG80BUOM)
Audio Amp (1watt) LM4890 ( smallest chip)
Unknown ??: Is this for TFT screen display ? ( Markings look like .. 48LCAM10A1)
FM Radio Function: SP3767 AHN

If anyone can identify the Unknown ?? chip, please post a description. ...thanks
