Hi, we have an unusual fault with a Mitsubish CT-25AV1BD (TV).
Can anyone help?

The fault is that the screen is blank with only the graphics being displayed, Q952 (2SC2236 transistor) was short and so was D957 (9.1 volt zenner).
None of the circuit protectors are open and we can find nothing else shorted or open.

Have tried resetting the eeprom.

Any ideas guys?

I had a similar problem a while ago on a 28" model and fitted the 8V regulator upgrade kit and had to replace IC301 (MSP3410) also.
IC201 (TEA6415C) has been known to cause similar symptoms as well.
