The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Coby 26" loses sound after a few minutes, any guess why?


Electronics can fail after they warm up. When they cool down again they start working again. The electronics need replacing, on this TV its cheaper to replace the TV.

The tube harnesses may be a little loose and when tube warms they short. Try adjusting the wiring harnesses. (Only attempt to do so if you have electronics knowledge.)

Hi,
In my opinion, you need TV-Technician to rectify the tv problem.
In case you want to fix it yourself, you should get its service manaul or schematics and enough knowledge of Electronics because TV has high voltage risk inside.

Hi,

Your concern is that the TV turns itself off. This could probably be due to any of several possibilities:
1. cold solder or loose connection, may maluwag na koneksyon sa loob o mayroong hilaw na hinang. Kailangan lamang itong painitan ng soldering iron upang muling manumbalik ang kinang at tamang pagkakapit. May mga pagkakataon na maaring maluwag din ang ACplug sa outlet;
2. heat induced - may pyesa na nag-iinit at tumitigil sa pag-andar pag mainit na. Kadalas ay mga capacitor, transistor or regulator;
3. low supply of the AC mains - mababa ang kuryente, maaring ito ma-check sa pamamagitan ng isang Voltmeter. Kung mababa nga, maaring gumamit ng voltage regulator kagaya ng sa mga computer;
4. timer - may mga pagkakataon na mayroong timer kaya kusang nag-switch off anf TV makalipas ang takdang oras;

Of course repairs would involve knowledge and familiarity with electronics circuitry and components, use of a DVM and a soldering iron. Should you be uncomfortable performing a DIY, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
