I cannot explain why the problem started with you changing the bulb and opening the contact pins in the cradle, but I can tell you that the problem with projection televisions shutting down randomly is typically caused by overheating. Due to the nature of rear projection televisions, this can become a common problem as the television ages. To prevent this, make sure that the air vent on the back of the tv isn't pushed against the wall, that the vent is clean, and not covered by something. Also make sure nothing that generates heat is near the television.

    Hey Dave. I have no explanation for why opening the contact pins helped when you changed the bulb, unless the bulb that you put in is somehow more susceptible to heat build-up. If it were my television, I would remove the bulb, clean any corrosion from the pins, and put in a new bulb. Then I would make sure that the vent is clean and clear and that I don't have anything too close to the television that could generate heat. (lamp, game console, etc.) I feel your pain!! lol When you have a big television, the last thing you want is it cutting out on you, since it will invariably be when something you really want to watch is on the tube! Anyway, I sure hope that you find a resolution to your problem and I wish I could be of more assistance. Best wishes.

Your TV has a short in the power supply, and or the sweep drive, sweep power supply,or the convergence module on this set will also kill the set from time to time. If you have a service manual, and a multimeter there with you and you know how to troubleshoot solid state printed circuit board, the first thing to do would be to get a service manual, located the convergence module, disconnect all the plugs to the module. Next pull off all three picture tube sockets off the picture tubes and lay them aside, making sure they do not touch anything.. Plug in the set. If it comes on with sound, you most likely have a bad convergence module.

Here are the specs and part numbers. Part Number: BP95-00415B, Description: ASSY SUB PCB-CG MOD, Stock Availability: Item usually ships in 5 business days, Price: $87.02. you get it here at http://www.samsungparts.com/,enter your model number If the set does not come on then your going to need to trouble shoot the sweep and main power supply's. I have had in this model the Hi voltage block cause this set to go bad once . If you have no electronic troubleshooting skills, Play it safe and call in a tech to assist you in this repair.

Replaced bulb but tv comes only comes on for about 10 to 15 seconds then shuts down and red light flashes


It sounds like you have a bad ballast board, or possibly the power supply going to the ballast bulb. I'm afraid that if you do not have the repair experience on solid state TV sets, you will need to contact and authorized Mitsubishi repair center. Good Luck

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.

WD-62327 Lamp


OSRAM VS. PHILLIPS
This is about buying replacement bulbs for the WD62327 TVs.I dont know about the other models but I purchased a PHILLIPS replacement bulb and it worked for about a week and then those dumb flashing lights and no TV. I did some research and others were saying that you had to replace some condensers. Shop would do it for 600 dollars..Well i sent the bulb back and bought an OSRAM replaement bulb. The TV is now working perfect.
