Tip & How-To about Daewoo DLT22W4T 22 in. LCD TV

DLT-32C3FTB

Hi.

This comment applies to Daewoo DLT32C3FTV. The system had in list only the model DLT-32C3FTB . Parts for the smaller model DLT-32C3FTB are available from the same sellers listed below. Troubleshooting is the same.

The stand by light flashing means that a fault had been detected, and the TV protection circuit had started.

Whenthis happen, the protection circuit will shut down all PSU highervoltages, keeping the low +5V to supply the flashing led on, and warnabout the fault.

The TV does not respond to control when in protect mode.


All you can do is checking all connections, and leaving the TV disconnected for a while, to drain charge held on PSU capacitors.
A short in a cable or connector will also cause the unit going on protection.


You can follow the instructions on this article, it refers mostly to DLP, but the troubleshooting is the same on LCD TV: Why my TV does not start up and remains in.

If you have done that already, that means that there is an internal fault.

Inthat case the best thing to do is contacting manufacturer at the numberlisted on the owners manual, and getting a quote on repair.

Onan LCD like this there are only few parts, a main controller, aninverter, a PSU board, an audio board, an LCD controller board, abutton and IR assembly, cables and the display.

The parts must be accessed and tested by a technician.

If the unit is less than one year cold, the repair will be covered bymanufacturer. In any case, if the TV does not wake up from protectmode, then it is faulty. Always better contacting Daewoo at the numberlisted on the owners manual.

Parts are available from Daewoo. A spare PSU, that is a common fault, is about £60 in UK. Here the spare:
Power Board FEL-3226H Daewoo DLT32C3FTV . Naturally that is not necessarily the fault.

Try first the troubleshooting procedure suggested above. If that does not work, contact Daewoo.
