Mitsubishi Toshiba Samsung DLP TV Bulb Won Turn On DIY Easy DLP Ballast...

power supply board caps or hv section of board.

The ballast is needed to start and regulate the bulb. I wouldnt recommend bypassing, unless you know how many volts the bulb needs to start(would need appropriate capasitor) and the watts/ amps needed to stay running (which would require a transformer) caps and transformers= a ballast, its easier to replace the ballast than build your own and risk it.

There is a ballast which drives the lamp--a hint would be to try to be in a position if possible to see if lamp ignites at all or even for a moment.

The ballasts do fail but rarely----it develops about 12,000 plus to the lamp and is much like spark plug wires as far as rf.

Some checks would have to be made and then the ballast priced--google the model number with ballast after it to get and idea.

No cut and dried solution here--several possible causes.

Hi W Bloom,


First of all, thank you for contacting Fixya.com regarding your TV problem.


My first advice is to do system reset by pressing the "Power" button key at the front panel and hold it for 10 secs.


Please check also if you can access the "Error Code Log" by pressing the "Menu" "3" "5" "6" "4" in sequence before the unit gone to shutdown.


You've mentioned that the bulb has been replaced just last Sept and now it won't come on. The lamp can't be test using the multimeter but you can make a visual inspection to determine its condition. Most of the faulty lamp has an obvious burnt mark. There's a possibility that the symptoms is caused by busted lamp but in your case, if it is a genuine lamp replacement, then high chance that the fault is not the bulb.


You need to check the ballast board but not the high voltage output of it feeding the lamp. No voltage coming out from the power supply board to the ballast board can produced the same symptoms. You have to check the this voltage at connector CJ1, you must get 325V to 340V. Check also the lamp enable at connector CJ3(pin 4) you must get a low voltage upon turning on the set to confirmed that the mainboard giving a signal.


If there's no voltage at CJ1, then the fault is on the power supply board.

If the readings are normal, and still the ballast won't ignite (you can hear a slight snap sound when the ballast board trying to ignite), then you have to replaced it.

I don't understand these questions

Any dash light you get is a Vehicle System
Malfunction ( no owners manual)

They have been with us for 30 years now,
still hundreds of questions a night

Study OBD2 Systems on the internet

All check lights need immediate attention

Check for Codes
Diagnose
Repair

Do so in a few days of any light on dash,they
won't go away & won't pass inspection & eventually
will end in costly repairs

What is the make and model of your set?

Check power fuse first, cheapest fix, if no power light comes on at all. Ballast (ballast booster) next possibility, if power light stays red, but cost is about $400 P&L. Finally, the bulb, if power light comes on, stays green, but no picture. Get the manual for your specific model.
