Rx300 Touch Screen Not Working

[Ken Sampson]

The reason for the next operation was intended to compare the digitiser screen with that on the unit removed from a 400h, to do this meant dismantling not only the defective unit removed from my car but also dismantling the perfectly useable but unsuitable 400h unit bought in error. First job was to remove the plastic outer shell from the defective Nav unit, the plastic shell comprising the air vent grills will later be fitted to the replacement (used) unit bought on eBay a day ago.

Attempting to get at the Digitiser screen the next job was to remove the switch unit mounted below - held by six self tapping screws, with the switch unit now dangling on its short multi wire harness the digitiser screen comes into full view appearing to be held in place by four screws, with these screws undone the screen showed no signs of wanting to release although the screen's ribbon connection became clearly visible and could have been disconnected using a pair of tweezers, at this point I had to review my future needs.

With a correct replacement (used) Nav screen due to arrive within a few days - and a now redundant perfectly serviceable 400h unit there is no point cutting OEM cable ties on the 400h unit just for the sake of making a comparison of the digitiser screen, but having gone this far it has been possible to identify the digitiser screen by a part number embossed on its stainless steel frame, the number, presumably manufactured by Futaba Ten, is: # 134835-121.

The new (used) unit arrived this morning, all plastics transferred and the unit fitted back into the car - less than an hour! But boy is it good to have the reverse camera back but in addition EVERYTHING now works...

Won't be attaching GPS sucker to screen any more - it's too expensive a mistake!

Very many thanks Chris for your help that I couldn't have done without.

So now have just the RX400h Nav screen complete with plastics vent grills for sale if anybody is interested.

Regards,

There seems to be some question of BBA-REMAN' s quality of work, thinking that there must be an alternative repairer there is, it is the OEM: Fugitsu Ten, they have a repair dept in Germany. Costs of such repair work can be found here http://www.toyota-tech.eu/TD2Legacy/Fujitsu%20Ten.pdf
