Title: Toshiba 22DL702B - Vestel - DVD monochrome
Post by: Turnip on November 24, 2014,04:38:29

Hi folks,

Have one in where DVB is OK but DVD plays in monochrome. Main board 17MB62-2.6

Any thoughts ? - Thanks - Chris.

Hi Chris,

I'd say this has to be a fault of the M-Peg board mounted on the DVD loader. Perhaps someone has previously replaced the loader with the incorrect type. Check MENU with the TV in DVD function. May be there's an option that needs to be changed. Just an idea.

Bruce.

Hi Vince and Bruce, thanks,

Hadn't thought to check RCU as works on DVB - Does nothing on DVD however so guess corruption somewhere.

Main or DVD logic ? - Thanks again - Chris.

You could try to do a factory reset, before ordering any part
press
Menu 4725
there should be a reset option in the service mode

Thanks Leo,

Had forgotten the Vestel biz. Getting old maybe, will go give it a go - Chris.

DVD menu Setup Code  is MENU 1357
Video Settings need to be set to Y/C or CVBS

The SPI Flash is on the Decode Board with the Blue Paint Stripe
but you will need copy from working version
sadly I do not have this

Thanks Vince,

Seems that the main board uses RC5 code but the DVD currently doesn't and therefore ignores the RCU in DVD mode - Work in progress to find a suitable RCU and flip it to RC5 - Gather current code is NEC whatever that is - Will search out NEC codes on my programmable RCU tomorrow -  Chris.

PS - Have found programmable remotes useless as they only give codes for RCU available from the Flea or Wiltsgrove. The odd ones needed are never there, no matter how many times one downloads 'updates'

Later - Got NEC code Toshiba RC1911 RCU from Wiltsgrove and flipped DVD back to RC5 code - no probs.
