The ballast board controls the lamp. The wires from the bulb attach to the ballast board. That board is your problem.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market.

you need a new lamp in it

I don't know who told you to replace it but, your part# is BP94-02059H this may change to pt# BP94-02084A see this website: http://www.shopjimmy.com/tvs/tv-digital-boards?tv_brands_select=Samsung&tv_models=Samsung+HLR5667WAX%2FXAA

Yes, this is considered a rear projection TV.

Hello, it sounds like the color wheel may have failed. Was there any noises, like a high pitch sound before it went out? If the color wheel isn't turning at proper speed, the set won't start up by shutting down the lamp protection circuit.

Hello, are there any sounds coming from your television? If something happened to the colorwheel I dont think the TV would come on at all, I would by instinct take a look at replacing the DMD chip.

The whining if it sounds like a mosquito type whine! it can be a capacitor, i have same issue, you can usually hear when u are on standby but if your hearing like a "wheel of fortune"! and slowing down would likely indicate it's a fan which is possibly covered in dust and the whining is the fan stopped trying to power forward or it slowly moving and slowing down. If you think it's the fan you should unplug your TV to avoid the fan burning out then have someone who knows what their doing take a look at than fan for you and clean the dust away from it, you may be able to get some access through vents in the side and can try your vacuum cleaner in those vents while TV is unplugged but i'd not go messing inside a TV without wearing some rubber gloves! Looks like the engineer would need to remove TV casing, check fan to see if it is blocked with dust or not, or if just failing for other reason then either clean or replace. If you don't get it done and the fan fails to cool the TV your risking other vital components overheating and breaking for good so best get it looked at, sounds like the fan to me...

Hello, It may be the new lamp is bad causing it to arc inside the lamp. contact who you bought the lamp from and see if they will replace it....tks

take the back of the TV off then take the power sores out and put a new power sores

I would guess that it could be the main board going bad. Check all our connections and wiring. You should call places like Tri-State Module and they can probably send you a part or repair for way less than 500 bucks.

Had the exact same problem with our tv the mother board is completely fried when the green lights streak vertical across the screen.

A darkened band on this model is almost a certain bad optical light engine--not much else can even cause this.

Two thoughts for you.One is the set has to be level and supported evenly across the bottom--it will cause this kind of issue.Second is look to the DMD board/box where the wheel plugs in--some had 3 bolts to loosen and if so the box can be shifted to set the center position of the picture--not easy as up moves it down etc.Usually if replacing this wheel you will not have this issue unless that has been tampered--suspect that light engine may not be back correctly in place--check that if you did not tamper with the DMD.

I think it should be the standard way for Samsung DLP's as posted elsewhere on this site which is:Power Off, then:Mute + 1 + 8 + 2 + PwrWhich will power up to the service menu...

Suspect number one is not fan, lamp or Color wheel--optical light engine with dmd is.

check the lamp.

Sounds like the lamp has blown very common problem. You can get the replacement lamp with installation instructions from www.tvrepairworld.com
