The ballast uses open ended high voltage. Both the start current, and the running voltage must be verified.

Normaly the ballast is replaced unless you have the test jigg which is essentialy the specified lamp simulator.

If there is a sensor fault that indicates there may be a potential cooling problem, or an unsafe fault condition (bad socket), or if the lamp is sensed as being defective, the ballast will be shut down.

hey there it sounds like the problem is coming from your ballast board, the ballast board is the power source to the lamp. with time this part starts to wear out and get weak your old lamp is already burning out there for it does not need that much voltage to turn on but the new lamp has not been worn out or used there for it needs the ballast to be working at 100%

hope this solution helps

I would suggest it is a ballast problem. You can check supply of 5 volts to ballast's small 5 pin connector (trigger voltage) and about 300V-330V to large 2pin connector. If both voltages present at the start and lamp is working with in another TV - it is bad ballast.

KF42WE610 bad lamp... and ballast?


Hi,
DLP Lamp has electrodes inside and ballast generates high voltage that makes spark on these electrodes thus got high bright light. New lamp wont die due to bad ballast so replace lamp and see tv works or not.
This tv has self diagnostic feature, turn On tv and let it shut down, now check standby light that would be blinking in specific order, for example 3 or 4 times blink then pause for 3 seconds and again blinks.
Let me know how many times standby light blinking in this tv to help you with more info.
Thanks.

Green timer light won't stop blinking


Hi,the most common failure besides the lamp it's the board that powers the lamp it's called the ballast.Most of the time that board was used to providing a lesser voltage to the old lamp so when you get a new one it uses more voltage(ballast has to provide 15 kv to power the lamp).The price of the ballast is less than the price of the lamp and it's something you can do yourself .This video is for a samsung but it will you an idea on how to replace it http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php Have a bless one!

340v should be on power pwb plug PL on the 1 and
5 (GND) pins for the ballast. and the ballast plug CN should also have the 340V with pin 1 of that plug being GND nd pin 3 should have the 340V If the PL plug on the power board is low the power pwb has a problem most likely the doubler circuit. If CN plug voltage is high say 360V the ballast is suspect.

Mitsubishi WD-65733 no picture, electrical buzzes in series


What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.

Samsung hlr5667w that won't turn on. Good lamp and ballast


Any light blink on the front. Whats the voltage to the ballast from the power supply. Common problem on these sets are bad lamp door switch. Try shorting the switch. Color wheel also is problematic but usually will be noisy and cause shut down. Check power board for swollen capacitors. Hope this helps

No Picture No Sound


Check the lamp first ,it could have blown.If the lamp looks good consider the following,The power supply gives the ballast the voltage it needs to strike the lamp,its hard to tell without doing some voltage measurements,you can not measure the output of the ballast but the voltage from the power supply to the ballast yes. Call professional help if you are not familiar with safety when servicing tv's.
