You posted to the category 'Kodak Televisions', there are over 10,000 categories to choose from, but let's make a wild guess that this is a Camera because that is what Google says you have. Although it could be a Copier, a Photo Printer, or even a Baby Monitor who knows, we can only guess.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name to your set, in its search box on the right side...

Glad to see you are up and running again.

This indicates that the Blue tooth pairing with the already paired device has been reset and the JBL Flip is ready for pairing with new device. This position, red and blue blinking, can be obtained by long pressing the power buton.

The chroma processor section should be troubleshooted. It is a skilled work.

1. Try SAFE MODE first.
2 If the problem is still there, format the disk and reinstall XP.

sounds like a touch membrane issue

Hi,

Restart your smart phone and restart your bluetooth as well. Then reconnect with your device. This should solve the intermittent problem.

Regards

1 Enter Pairing mode.
• Turn off your headset and press and hold the Multifunction
button until the blue indicator light remains lit
after blinking.
• If you turn it on for the first time, it proceeds into Pairing
mode immediately.
2 Search for and pair with your phone according to your
phone’s user guide. (Bluetooth PIN: 0000, 4 zeros)
• If the pairing is successful, the blue indicator light will
flash 10 times rapidly before entering Standby mode.
• If the blue indicator light remains lit, retry pairing.
Pairing with your Bluetooth phone
When the headset and the phone are paired, the
headset attempts to reconnect automatically each
time it turns on. Otherwise, press the Multi-function
button to reconnect.

Thats a common problem when the Caps on the DM are bad the set will continue to operate as long as it doesnt get unplugged, once the plug is removed from the wall then the dM cant complete the boot sequence again untill the caps are replaced. Its a very easy repair and the repair kit is very cheap and comes with step by step instructions. Here is a link to the repair kit for your model
