SOURCE: TV WILL NOT POWER UP

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.

with lamp out (door closed) the ballast should "strike" or give an arc sound, trying to fire the lamp. If it does not do that maybe the color wheel is not spinning up - has to do that first.........then the set will try to fire the lamp

Yup definitely sounds like the ballast, if not then you have a problem in the power supply. Probably some bad capacitors. Call a local tv repair shop.

How can you tell if you have a bad lamp or ballast on the Sony DLP KDS60A3000


Remove and examine lamp to see if shattered--lamp has a 2,000 hour lifespan and may look good--if it fails the lamp light on sets front should light.

A ballast is harder to call--can check the approx 300 volts from the power supply to see if it shows at ballast.

Video instructions for lamp replacement are by model number available on You Tube for most sets.

I have a infocus IN35 that at 100 hours burnt out a bulb. Thinking that it was just a bulb problem I bought a new bulb and it lasted 20 minutes. a t.v.repair shop said its probably the ballast that is the...


It is not a common problem. Ballasts rarely need repairs. Have you reset the lamp hours to zero after installing new bulb? If, yes to confirm about ballast please ask the TV repair shop man whether previously he had repaired any DLP projector. There is lot of difference in technology of DLP projector & TV (except DLP Projection TV). The problem could be in the projector main board. The lamp lights after getting Lamp ON signal from the projector main board. As the lamp ignites the ballast sends the signal of Lamp Lit. If the projector board senses that any blower/exhaust fan or colour wheel is not running then it will send a signal to Switch OFF the lamp. If you are tech-savvy then do as follows to check about lamp & ballast. Remove 5 pin connector from the projector. Connect projector to mains supply. Get a 5V DC power supply. Connect +ve to pin 3 & -ve to pin 4 of the ballast connector from this supply. The lamp should light. If it does not light then there is problem in the ballast (if the lamp is new). To give a chance you can check it for your lamp which lasted 20 minutes. Generally ballasts are made by OSRAM. You can get the ballast from OSRAM dealer. You will need the part number for that. Take out the ballast, it is there on it.

JVC DLP MOD#HD55G466 what is the voltage from power supply to ballast and into the lamp.I have no voltage to the lamp could it be ballast?


Hi,
Ballast board gets voltage from power supply connector CN90BL and volts readings are as follows:
Pin-1 = 380V DC
Pin-2 = Ground
Pin-3 = 15V DC
and output of ballast board would be 12,000 volts AC that goes to lamp to generate spark in its electrodes to produce high bright light.

If you get volts on input of ballast board but still lamp does not fire up then ballast board is not working.
Ballast board part number is QAL0765-001 and available with tv-part.com for $125
Hope these info will help you.
Thanks.

I am trying to locate the position of the ballast for a Samsung DLP, model # hlt5075s tv. I am pretty sure this is the problem w/the tv going dark after several minutes and have a description of how to...


Hello,
The ballast is easy to locate. Simply follow the two wires from the lamp connector. They lead strait to the ballast board.
The symptom you describe could also be a lamp if you have not yet checked that. As the lamps get older their resistance increases putting stress on the supply or ballast. You may see fluctuation in brightness or the lamp may power off after a time but will not yet be competely blown.

Why does my samsung tv cut off by itself after 1-2 min and flash a red lamp button?


A little explanation first- this model (as do most Samsung DLP sets) will try 3 times to get the lamp lit before the microprocessor will give up and then the 3 lites on the front will blink indicating a LAMP failure. This process takes about 1 to 2 minutes. In order of probabilty, the failures are:
1) A faulty lamp and/or ballast. REPLACE LAMP AND/OR BALLAST
However, a faulty lamp and/or ballast are not the only things that will give this blink code-
2) If the color wheel has a bad bearing and turns too slow or not at all, the microprocessor WILL NOT let the lamp light, and then give a LAMP blink code. A bad color wheel will normally have some sort of abnormal sound- a low growl or high pitched whine is common. REPLACE COLOR WHEEL
3) ALSO, if the microprocessor (on the DMD board) in its color wheel rotation detection or processing fails, once again the lamp is prevented from coming on and you get a LAMP blink code. REPLACE DMD BOARD
IF THE SET EVER COMES ON WITH A PICTURE for even a fraction of a second or though it takes many tries, the lamp and ballast are good. The problem must be either the color wheel or DMD board.
