RPi3 RetroPie Buster and JVC TM-H150CG

Looks like a VSync mis-match. Does the monitor work with other composite sources ?

@mitu As you can see I've got PS1 there and it works flawlessly with composite cables.

What's your config.txt ?

Trendkiller-9

@mitu Sorry for the delay, here's my current config.txt:

# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)

~~If your TV is a NTSC set, why are you trying to send it a PAL signal ?~~
In your config.txt, you've set sdtv_mode=2, which is PAL. Try using one of the NTSC modes:

stdv_mode = 0 (Normal NTSC)
sdtv_mode = 16 (Progressive scan NTSC).

See the entire list of options at https://www.raspberrypi.com/documentation/computers/config_txt.html#sdtv_mode

@mitu was one of my thoughts as I've sawn that config.txt, but AFAIK the TM-H150CG supports PAL&NTSC, at least the ones that where sold here in germany did (IIRIR). So I am curious now if that really will solve the issue ;>

Edit: Ok, just wanted to verify my memory... the manual (to be found on a well known library side) (~~EN, page 18~~, sorry service manual: page 1-2) cited: color system: PAL, NTSC (3.58), Scanning Frequency: H: 15.734 kHz, V: 59.94 Hz (NTSC), H: 15.625 kHz, V: 50 Hz (PAL) -> now I am really curious about it!

Trendkiller-9

Again, sorry for late resposne.
As I mentioned in the earlier post I've tried all of the available options for "sdtv_mode",
so probably it's the faulty cable. What do you guys think?

Ashpool

@Trendkiller-9 Maybe, but haven't you said "even bought new cables, issue still exist"? I assume you bought ones designated for the pi (TRRS-Standards), but I really don't know what one would get displayed on a CRT with one of the other cable-variants. Any chance to test it on another display?

Trendkiller-9

Ok guys, problem's solved. It was cables fault. Even if it's TRRS standard it's not 100% certain to work.
Best option to buy cables from verified manufacturer. I bought cables dedicated to XBOX360 E and it works!

Nevertheless, thanks for your time!

Ashpool

@Trendkiller-9 Glad you solved it :D
