This is the second time the bulb has failed on my t.v. The first time was no issue, bought a new lamp, replaced it, and it worked. This time- lamp goes out, I purchase new lamp, installed, still didn't light-up, Toshiba replaced the lamp, installed new one and still not working. The red and green lights are still blinking together in 1 sec intervals. Any ideas? Toshiba isn't much help and the nearest tech center is 200 miles away. Thanks!

I would venture to guess the bulb figment is your issue and the electrical sound is most likely arching (very bad). The cheap replacements won't last. I bought a sylvania build and matched the model number with the one from inside the old bulb housing. Changing out the bulb from the casing is really easy so just return the one you bought and buy the corresponding bul without the case.
Reset the lamp hours as follows. Press the Exit button on the projector for 3 seconds to display the total used lamp time. Press the MENU button on the projector during the lamp hour message. An adjustment message will appear. Press left or right arrow to reset lamp hours or press EXIT to leave.
Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.
Failed caps on the power supply will cause that. The V26 Power pwb repair kit will usually correct that issue. Its available from www.tvrepairworld.com the kit contains the capacitors and the CD with instructions.
this is something which sharp didnt foresee!!!!!!!!!! sharp has two identical models sharp xr10x & the newer model xr10xl.both the lamps look alike , however both have a different rating & reverse connector!! i.e both cannot be interchanged!however if u have the old xr10x & if u try to fit the new bulb which is lower in wattage, it will explode in 20 mins if you have bought a used projector , then u wont know if someone has interchanged the ballast!! as this model was discontinued 2 years back!!!! so confirm the model , it is mentioned under sharp name or at the bottom good luck
I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.
Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.
When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.
When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.
I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.
Once I did all this the TV turned on the first time and has been working fine for three days now.
I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.
I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.
