See if any of these might help: --------------------------------------------------------------- Text pasted from WinSTIPS 2.0 http://www.ServiceSoftware.com --------------------------------------------------------------- DAEWOO DTQ26S1FC Dead The Service Bulletin Notes For The Regulator Circuit Said To Check The Following Out Of Circuit: R818 (.33 Ohm 1w), R806 (390k 1/2w), R812 (100 Ohm 1/4w). Failure On These Are Highly Possible Due To Thermal Runaway. Then Test Q805, Q803 And Q804. To Test You Might Remove Q402 (Hot), And Use A 25w-120v Bulb Across The 103vdc And See If It Flashes. Replace C404 1mf-160v With A 3.3mf-160v No Matter What, And Place A 33 Ohm 1/4w On Q402 Between Base To Emitter. In My Fix I Had To Replace Q402, And Then Added The Resistor. The Notes I Have For Crossing These Are: Q402 - D1880 - Nte 2353 (Hot) Q803 - C2500 - Nte 2363 Q804 - E13009-2 - Nte 379 Q805 - C3203 - Nte 382 --------------------------------------------------------------- DAEWOO DTQ26S1FC Dead - H.o.t. shorted & Fuse blown Herman Ackerman Q804E13009-2 (Kse13009y) I used 2sc4834, Q805 Ktc3203 used 2sc3203 h.o.t. 2sd1880 used 2sd1879 ok. --------------------------------------------------------------- DAEWOO DTQ26S1FC Dead - H.o.t. shorted & Fuse blown Jesse Morris Q402, Q804, Q805, C403, C418, and F801 --------------------------------------------------------------- DAEWOO DTQ26S1FC Dead No Power Up Computer & Comm Solutions Www.Ccsinc.Com 804-642-9731 Q803 C2500 R/W Sk9453, Q804 E13009 R/W Sk10000, Q402 2sd1880 R/W 2sd1879, Q805 C3203 R/W C3203 C404 1uf@160v Had Bad Esr --------------------------------------------------------------- DAEWOO DTQ26S1FC Dead No Power Up (All Smps Components Check Good !)
