Samsung 46inch Slim DLP - No Power, buzzing/crackling

The TV has been randomly shutting off on me recently, however It would turn back on. Today when I got home I noticed the lights flashing on the system. So I tried to power it on. The sound I hear is not so much what I would describe as a buz, but more of an electrical crackle. It does this for a moment, then stops, then does it again, then stops, and continues untill all three lights begin to flash on the system. I took the system apart, and tried again with the guts hanging out. I notice that 2 things are happening simultaneously with the crackling sound.

1. A small piece on the ballast is illuminating and someone flickering with the sound of the crackle.

I uploaded a picture of the part im talkin about here...

2.The lamp appears to flicker faintly as well. I removed the lamp and it does not appear to have any damage to it. and doesn't appear to be burnt or have a broken filament.


The lamp has been replaced recently, within the last 5 months or so, I don't recall how long. I'm wondering if my thoughts of it being the ballast is correct here because I'd rather not waist 100$ on a replacement. Thanks in advance, any other questions just let me know.

The ballast board has mounted on it what is called a spark gap. When it fires the lamp it makes a crackling noise and it does light up from the spark. This is normal. If the lamp doesn't fire or won't turn on completely it will try several times. I would replace the lamp. Although if the big capacitor on the ballast board is domed on top then replace the lamp, ballast and power board at the same time. There is a serv bulletin on this but only if the capacitor is swolen. I hope this helps.

Well, you definetly right...... The driver of the ballast is busted, now the ballast is to weak to maintain on that lamp. I will recommend to stop trying to turn ON tv since this could damage the bulb by blowing it from inside. I will recommend to change ballast and the old lamp should work for a little while (since I am quite sure that this bad ballast is consumming faster that lamp). Or change lamp and ballast as well that shouldnt cost you more than 200 in booth things.
you can have the ballast from samsungpartsdotcom or i also had purchase some from discount-merchantdotcom (excellent service)

TV Turns Off Automatically While Watching


Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.

You need the bulb repleaced in the back of the t.v. You need to call your retailer to find out which company they use and or if you have a warranty they can replace it for free.

Hitachi 51F500 (Two separate problems?)


My guess is that the sound you heard was that of some High Voltage discharges that could have fed back and damaged some semiconductors including the microprocessor itself. Since it could be a very expensive repair, I would be very tempted to look around for a new HDTV by JVC or Toshiba. Hitachi has slipped a notch or two in recent years according to my experience.
