...sound with samsung 52 inch dlp tv . works fine Need to adjust the vs voltage in the power supply is to high, you have to use a multimeter on dc voltage and only go down 10% of the actual

...DC voltage suppled by the correct power supply. The TV will not turn on now. Is this somehting that can be repaired or is it beyond help? It seems your "power regulator" a small unit inside tv device ...

...DC votage should be 70% rating of the capacitor voltage. If the capacitor is dry it will show low voltage. But the diodes should be OK. Check the high wattage resistors connected in the power supply. ...

...voltage conversion on a switching power supply, Modern TV sets have switching powers supplies that converts the 120V AC to DC voltages that drives the circuits. You may have to replace the power ...

...DC output because it is low-voltage. Placing the probes of a volt-meter (in the appropriate range setting) across with the black (-) lead to ground and the red lead on the high-amp positive lead, ...

...chattering due to insufficient voltage being applied to keep the coil active or the transformer secondary is not providing the correct DC voltage to power the control board. Suggest a replacement ...
