Thank you, XXXXX XXXXX please verify the model number?
Do you need any additional information?
Thank you, XXXXX XXXXX lamp been changed before or recently?
No, we bought the tv in April 2007 and it hasn't been changed in that time.
The lamp is the first component to suspect if it has not been changed.
Ok, how do we determine if the lamp is the problem. Is it trial and error, or is there another test? Also, where do we get a lamp?
Yes, the lamp must be replaced first based on your symptom. You can view a complete assembly at this link.
