I own trv250 and same black screen issue appears. After reading on the net that this model is prone to ccd failure......also I have read that you can swap the ccd unit from trv350 which is more reliable. Please advise if the above is true and what would be the cost ofr 350 versus 250. Also if not possible then whats the gaurantee that the replacement part will not die on me. How fast I can recve if ordered from you. thanks awq
