Hi Debbie and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model number of the "...Sony rear projection tv..."
Appreciate the additional information; a Sony KDF-50E2000.
And yes, an XL-2400 is a replacement.
Was it just the bulb/amp that was replaced? ...or was it complete assembly with housing?
It's alright and thank you for your kind understanding of automated / machine generated system offers / services.
Have you re-checked and ensured that the lamp cover / door is fully closed and locked ?
Unfortunately, if the lamp cover / door is confirmed to be fully closed and locked, then it would be the door sensor that may have faulted. It would be an internal hardware issue.
Based on "...find a repair service...", would you like a LINK to possible repair shops near you?
Sorry Debbie but my participation is strictly limited to technical, repair and/or installation issues; not on billings & payments.
Still, please click HERE.
Select your location/state, key in your Zip Code and the click on the Submit button. New page would display list of TV repair shops.
Again I understand and no prob.
Request for cancellation, refunds as well as billings & payments concerns are best addressed by Customer Support. Please click HERE or go to http://ww2.justanswer.com/help
Good luck Debbie and thank you too for trying this site.
