Facing TV Problems? Ask a TV Technician.
Hi Ashley and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, is the Coby completely / electrically dead?
Have you tried unplugging for an extended period of time? And then plugging back in but using a different power source / outlet?
I understand and this would indicate an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach?
Great on the DIY Ashley!
Do you have access to and familiar with a multi-meter and even perhaps a soldering iron?
Post back with a clear picture of the insides of the TV with the back cover off. Please click HERE.
And agree on the two (2) likely suspects.
Appreciate the picture.
First test is on the power cord. Set the multi-meter to Ω and test the continuity of the 2 prongs of the AC plug to the 2 pins of the connector to the power supply board's AC INPUT:
Please post back results / observations of the above once tried.
Yes please; when able.
With the meter set to Ω, what is the reading when the red probe is touched to the black probe?
Red probe to 1 of the prong of the AC plug and the black probe to 1 of the pins of the connector to AC INPUT. What is the reading please?
Try the other
And then repeat with the other prong.
I understand. With the power supply board unplug; how about the fuse; leg-to-leg, what is the resistance?
Let's try again the earlier request; "...Post back with a clear picture of the insides of the TV with the back cover off..."
