My WD 57733 will attempt to power up (almost like a whistling sound as it attempt to power up) then will power back down.


When was the last time you replaced the lamp? That sort of sounds like the ballast is unhappy with a bad lamp. The 57733 is a good TV. The other possibility is a stuck/dirty color wheel.

Check the lamp and see if it looks worn out(dark or grey in the tube down the center). Also make sure its either a Philips brand or Osram brand.

Let me know and Ill see what I can recommend next

If the lamp is new and good to go then you may have to reset the lamp replacement counter in your setting menu. When that is set back to zero you wont have a problem until it is time for a new lamp again.

My Samsung HL-85679W DLP LCD TV has sound but no picture


Look to see if there is a little green light on the bottom of your case, this would indicate the bulb is working, if the light is red, you need to replace the bulb....good luck

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sound but no picture.


Is this a 3-gun projector style or an LCD?
LCD has a lamp . If its a 3-gun system, then it's probably in the High Volt section on the unit.

Time to get a tech to troubleshoot it in person

Picture on TV


Your problem sounds like it could be a vertical sweep fault. Sounds like a vertical output IC or a capcitor in the sweep power supply or a waveshaper capacitor. All these faults, should only be checked and replaced by a pro tech, as there is a safety issue involved with the High voltage, and your going to need to know how to use the equipment to check these parts as in this case , you most likly wont be able to look and see whats wrong or what part is defective. Good Luck
