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?

Mine was making a screeching noise for a few seconds then stopping then doing it again on and off for around a minute. After this it clicked and the lamp indicator light on the front of the. Tv went red and nothing else. There is no picture at all during this process.
I thought it might be the lamp that had gone but after looking on forums most people said that their pictures gradually got darker over a period of time before it completely failed and mine had not done this. In the end I wimped out and took it to local repair shop for them to quote for repair. They have confirmed it's just the lamp but as they only deal in genuine parts and I won't pay over 200 quid for a Sony lamp they charged me 30 quid for checking it and I have ordered a lamp from Kinetis lamps for less than 70 quid. Fingers crossed the repair shop are right and it's only the lamp..!!
FOX has Lamp for $109.00 1-800-227-5369
Encompass Parts has Ballast $54.43 1-800-638-3328
Encompass wants $150.00 for lamp Your TV is a Samsung it will be on Right Hand Side of TV and I would Just Replace The Lamp First? What was your TV doing to begin with?
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.
Although this is rare, the problem is the lamp driver board, commonly called the ballast board. Follow the leads back from the lamp an you will find a smallish rectangular board with one large connector and one small one (besides the two wires going to the lamp). If you feel confident, they can be ordered from a Sony parts distributor such as Vance Baldwin or Union Electronics Distributor for about $115 - $150
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
