Too HOT to handle? Daewoo DTQ27S2FCV.

The NTE is not a good sub in that set. Follow the service bulletin, required, for the overheating and blowing HOT problem in that model. Plus there likely will be a bad cap on the HOT driver circuit.

I no longer have a copy of the service bulletin, but if Daewoo is still in business they can email it to you.

As I recall, the bulletin made some changes to a couple of parts and added a 39 ohm resistor across the B-E of the HOT as well.

Daewoo is still in business. Along with my parts order, they sent me an unsolicited application to be an authorized service center. When I called and asked if the HOT failure was a common problem, the technician told me no, and suggested that replacing the parts with the originals would fix it properly. I'll call them back and definitely ask them about the service bulletin.

Thanks for your reply.

Replace 1.0 uf electrolytic capacitor in horizontal drive...there maybe two in this area. This is what kills the set, if it's shutting down, & you keep using it.

Just search this kit. DAE-SPKIT

0.33 OHM 2 WATT, 100 uf @ 25 volt electrolytic capacitor in thePWM power supply, resolder the degaussing thermistor. This fixes these T.V.'s most times. Hope this helps you. Dani.

Lest everybody forgets any and all solder bad/cold connections in the HOT drive circuit will also cause the HOT to heat up and blow. The cold joints cause noise in the base circuit and this high switching speed(noise) causes the HOT to over heat. If you take a 50X magnifier and look at the joints, that are bad, you can see the cracks in the solder. Learned that from a SONY service flash but my in experience it applies to any HOT circuit.

In any Daewoos I repair, I change at least four caps, two in horizontal circuit (2x 1uF 160V) and two in power supply while replacing or repairing them for any reason.

Mod on that horizontal is new to me. I'll keep that in mind.
