Hello all - I'm a new to this forum so please be gentle.
My problem is a Toshiba 24D1333B2 with Vestel psu 17ips61-3 & motherboard 17MB95S-1
This TV died with the red/green flashing light problem reported elsewhere on this forum. I replaced all the diodes and, as a precaution, also the smoothing capacitors. My 'scope shows the supplies as smooth but slightly lower than nominal. Powered it up and still had the flashing light. Downloaded the firmware files (mb90_en.bin, mboot.bin, usb_auto_update_A1.txt) and installed them but now, no picture. The set responds to the remote, turning on (solid red -> a couple of red/green flashes -> solid green) and off (-> red). There is a 'flash' across the screen at switch on then nothing. The screen LEDs are definitely on. Pumping a HDMI signal in gives sound with volume controls working on the remote. I have no circuit for the motherboard. So, anybody any thoughts about where to start?
