My husband has a Samsung PLH403W TV that we thought had a blown lamp. We took it to a repair shop and they said the motherboard was bad and replaced it. We got it home and it continued to say it had a bad bulb. I just received my new bulb and it continues to say the bulb is bad. I installed it and attempted to turn the TV on and it made a clicking sound like 3 times and then all the LED lights started blinking indicating a bad bulb. Anyone have any ideas?

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php Also make sure the door cover is closed because there's a switch that if it's not pressed it won't let the lamp light on.Have a bless one!
Rulds2008 is probably right. I had the same problem, but have no TV repair shop near me. So since I have experience fixing computers, I decided to repair the TV myself. I initially repaired the Lamp, but the TV still flashed all three lights. Called Samsung and they told me that I might need to replace the ballast, but it would be best to bring it to a repair shop. The repair shop offered to come out and look at it for $150 or bring it in for $120, even though they were about 30 mins away. Ordered both parts on www.Samsungparts.com and got them in three days. Still had the three flashing lights. Took apart the entire TV (googled it on youtube) and vacuumed and dusted the TV and took apart the color wheel (about 20-30 mins). It was completed busted. Found out that if the color wheel is broken, it will not send a signal to the ballast to tell it to start up and power the lamp. So if you have replaced the lamp and/ or the ballast and it does not light up, it is more than likely that it is your color wheel (buy it on ebay or amazon, got it in three days versus a 3-4 week back order on company sites). Also, make sure the power switch on back is being pushed upwards and not downwards or the TV also will not start. Total parts cost me ($400) versus having someone else fix it and charge me double with labor and parts. TV is better than ever. Hope this helps.
I believe you have convergence problem on your rear projector TV. It require to replace may be 2 IC output convergence or the convergence drive, after replace those component you need to readjust convergence which mean you move the RED GREEN BLUE to be 1 on top each other you must have the remote control and service manual to get into the service mode, if you thing you can get those part in your country the service manual I may help you with that, ask your husband if he like to challenge it. I hope that is give you some ideas
Did you use an original replacement lamp or an aftermarket replacement? From the price you give, it sounds like an aftermarket lamp, which are notoriously buggy and the problem may be with the lamp. If not, the lamp driver is your next likely culprit. It is also called a lamp power supply or lamp ballast.
Here is how you get to the service menu. Just be sure to write down anything you change in case you want to change it back.
1. TV turned off 2. Press 'Mute' then '182' then 'Power' buttons on the remote. You are now in the Adjustment mode
4. Use the 'Channel up'or"Channel dwn' to select the category. 5. Use the 'Volume up or dwn' to enter the category. note:Some models may not have Category Selection. 6. Use the 'Channel up or dwn' buttons to select item to be adjusted. 7. Write down the old value of the item before changing. 8. Use Volume up and down adjust the value. 9. When you have made all the adjustments you want turn the set off to exit.
