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

Hi, I had same problem (on tv-out, only sound) and problem was that cable, it dosen't work correcly, somtimes it works, and somtimes it dont, try anothr cable.

also my tv out cable goes to head-phone jack.

EDIT: and to get playr to tv-out mode:

Go to main menu, and select options>TV mode>PAL(or NTSC)
then go back to options menu and select TVSWITCH and select on and plug your tv-out cables to tv and then to your player, thats how it works on my mp5 player (product name: S400, major version ID: 3.0, hardware ID: RK2706)

Oilburner2,

Your player looks identical to mine. I also have a problem. I have sound but my video output is Black and White. My chipset is the Ingenic 4725 described by Autofils. Its driving me crazy if the player is defective or if I have a cabling problem. I live in the USA and have set the player to NTSC and other than the color problem, it looks OK. Have tried direct connect to my TV, through my VCR, a standalone VCR with A/V inputs etc. but nothing out with color. Communication with the vendor is frustrating. And now my TF card fell inside the player. It is still functional but I worry that it might short out ? Too much trouble sending it back. I'll have to check with Autofils to see if its too difficult to open the player as a last resort. I guess noone had this problem either. Seller has excellent reputation in Ebay.
Did you get it working yet ?
