Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do mybest to help.

Initially, is the Sylvania completely / electrically dead?

Customer: replied 6 months ago.
No. the red led is on steady....not blinking. when I hit the power, the green starts blinking like if its coming on. After blinking about 8 times it stops blinking
Expert:  Louie replied 6 months ago.

The described symptom almost always points to an internal hardware issue. The systems is detecting a fault thus kicking in auto-protect mode.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter (and even perhaps a soldering iron)?

Customer: replied 6 months ago.
sure I would like to repair if possible. I will look for the multimeter and soldering or even buy them. How should I contact you when I have the equipment?
Expert:  Louie replied 6 months ago.

Post back when available.

Also please provide clear picture(s) of the internal circuit board layout to serve as common reference. Click HERE.

Customer: replied 6 months ago.
ok..i will send you the pics and post back when I have the equipment. do I have to pay again when I post back?
Expert:  Louie replied 6 months ago.

To my understanding:

  • no additional payment if an update is posted in this same page;
  • new question page = new payment;
  • additional premium phone call service = add payment;
  • electronic copy of the scematic diagram = add fee;
  • complete service manual = add fee.

I should be able to come back to this conversation and simply continue working with you with no additional payments. Correct?
