Sony regard the above as old technology and do not seem to be interested in repairing. Perhaps someone here knows of someone/firm who would. Here is the problem: The unit switches on as usual but within a few seconds (about 10 - 15), the lamp, which was on correctly, switches off and the on/standby light flashes. The filter has been replaced. In fact, I've removed the filter and manually engaged the micro switch associated with the filter. No effect; the lamp switches off as noted above. I've removed the lamp and reset it back in the unit. This has no effect either. As a new lamp is relatively expensive, and bearing in mind that it lights up each time for the 10 - 15 seconds period, can anyone suggest anything else (apart from sending it to the electronic bin)? I've also done the reset protocol: left arrow, right arrow, reset without success. In addition, I've bypassed the lamp thermostat but the problem persists.
