Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

1 Answer

My screen went blank and the 3 lights on the front of the tv were flashing (lamp/temp). I ordered, received, and replaced lamp as I had done previously with this problem. The tv worked beautifully for about 40 minutes and then the picture and sound went off again and the lights started flashing again. I unplugged the tv as it was unresponsive to the power off button. Please help.

Hi,do you hear any strange noises? if you heart clicking or like wanting to turn on it could be the ballast that's the board that powers the lamp.Do you hear buzzing,whirling,or high pitch sounds?If you do it could be the color wheel which is a little disc looking that when the light of the lamp goes through it creates the colors on the tv.This are the most common failures on samsungs.

When I turn the tv on it came on for a minute then started flashing on and off then went blank but the power light keep flashing off and on with a blank screen.


This problem is easy to repair. If when you turned the tv on and it had sound and picture for a second or two, and the power went off and the power green light keeps flashing on and off, it is a bad CCFL backlight lamp inside the LCD panel which has 10 of these lamps in it, but only one is bad. Replace the lamp and the tv will power on. What the tv is doing is, it has stored a lamp error code on the main board and turning the power off. The replacement lamp is part # RLMPLA029WJN1 and you can buy them at www.encompassparts.com for $19.49 ea. Go to their web sight and sign in as guess to order. I can give you step to step instruction on how to check how many lamps you will have to order if you need me, too. You will have to take the tv apart to check them.

Hitachi projection tv quit


Pls check that model number........the problem description does not match that of a 1999 crt proj tv.........I believe yours is a newer lcd projection around 4 or 5 yr old?? Lamp light flashing on any brand is indicative of the lamp not lighting . The lamp is the most likely cause,but the ballast board can cause this as well..................you should see an access door refer to owner book of the correct model and you can replace yourself...........it may cost around $200 and avaiolable at encompass parts .com Hitach distributor

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
