hi,
You have to check the lamp ballast supply board. If the Lamp ballast board is faulty the it will burn the new lamp installed. 5 blinks means the lamp is faulty. can be caused by faulty lamp ballast. To deal with the lamp ballast you should need a good knowledge in electronics. Because electric shock risk is involved. Also you need a new lamp

---------------------------------------------------------------------

Please read carefully!
FixYourDLP.com has identified a potential hazard that may severely damage your Samsung TV with lamp code BP96-01653A!
Samsung DLP lamp units, model BP96-01653A may fail due to improper insertion. We discovered this while doing some tests on these enclosures. If you don’t install the BP96-01653A firmly into the TV, the housing connector may cause damage to both the ballast and the lamp—or even worse a fire.
You’ll know immediately if there’s something wrong because as soon as you turn your television on, and there’s white smoke emanating from the back of your television.
You should shut your television off immediately and open your lamp door and pull out that lamp. Inspect it and hopefully, you’ve just burned the connectors to the ballast, and not the ballast itself. Our testing has only caused the connectors to burn or melt, but don’t take any chances—we’ve never seen a fire, but we also don’t rule out the possibility of fires either.
Here is a correct installation method and the reasons why a bad installation will cause the connectors to burn:
IMPORTANT SAFETY WARNING
Regarding the installation of a BP96-01653A lamp unit into a Samsung DLP Television.
Installation
Step 1
install_images_bp96-01653a_01.jpg
Figure A – Open panel, lamp unit removed
You must install the lamp unit to fit snug with the ballast connector.
To do this, align the lamp unit with the female ballast connector facing down, on the bottom side of the enclosure, then slide the lamp unit until it snaps into place. Check to make sure the unit is firmly inside the television.
Step 2 install_images_bp96-01653a_02.jpg
Figure B – Snapping the lamp into place
Snap the wire brackets in tightly by lifting the bottom set up to meet with the top bracket. The wire bracket keeps the lamp and lamp enclosure seated properly to reduce the risk of fire.
when installed properly, the unit should sit secure and slightly elevated from the floor of the compartment.
Step 3 install_images_bp96-01653a_03.jpg
Figure C – Close back panel securely
Once the lamp is firmly secure, close the back panel to engage the blue lamp door sensor switch. Leaving the door open will prevent the television from starting up.

Important Damage or Fire Warning
Because of the nature of the ballast or lamp driver, there is a risk of damage or fire to your television set.
The ballast ignites the lamp with up to 20kV of electricity to arc the gas tube inside. If the ballast does not have a firm connection with the lamp unit, the arc will occur between the ballast connectors (from the ballast to the lamp), which may cause a fire, or melt your plastic connectors. Indications of this are a rapid clicking sound, a burning smell, and/or a non-functioning lamp. If you improperly install the lamp into your television causing a ballast or lamp failure, this may void your warranty for the television or the lamp product.

My KDS-50A2020 TV has an error code indicating a lamp driver fault (5 red blinks). I replaced both the lamp and the ballast and it still doesn't work. I need further assistance troubleshooting the...


Hello.
Ballast in Sony is one of the most reliable parts, almost never goes bad.
I assume you have TV unplugged from the wall outlet to reset error memory (not to mention that you have to do it anyway during ballast replacement).
I hope you are using good quality lamp, because cheap substitute from E-Bay can cause same problem. Lamp and ballast works as duo and on-board diagnostic system is unable to separate them unless lamp is completely blown (in that case you will have steady "Lamp" LED blinking).
You need to set TV up with back cover removed but lamp door attached (there is switch that prevent TV from working if lamp door is removed). You need to locate large 2-wire connector on ballast and make sure that it's getting about 330V DC from power supply board when you turning your TV on. If it's not there - you have power supply board problem. There should be fuse on it (not on the ballast board but power supply board - just trace those two thick wires where they coming from). That fuse could be blown by previous bad ballast shortage.
Small connector on ballast have 5 pins. Some of them ground, one of them steady 5V and another trigger (turn on signal) 5V. Make sure all voltages are there. If there is no trigger 5V - you have problem with main board.
In my experience 90% cases - it is very bad quality new lamp or something is just not connected (forgot to put plug all the way or something).
Good luck!
Russ.

Mitsubishi WD-57732 LAMP continuously burns out. I have replaced four in two years. We don't watch alot of TV.


There are a few issues here:

The lamp you are purchasing could not be OEM, or a compatible lamp--OR you have a ballast/power supply issue blowing the lamp out.

The original lamp is manufactured by Osram, but a better and compatible lamp would be Philips, who pioneered the lighting for DLPs. The ballast needs to be compatible with the lamp and Mitsubishi ballasts are compatible with most lamps, but work best with Philips and Osram. Only buy from an authorized dealer!

Panasonic pt-50lc13 it just will not turn on,but the red light is on and the lamp was replace


Is the lamp indicator light flashing? A new lamp may not solve the problem. The known problem with lamp failures is poor voltage output from the ballast,.. a problem Panasonic refuses to correct and they decided to no longer provide the repair part through their supplier in an attempt to sweep this problem under the rug.
Lamp light flashing once every 5 seconds or twice every 5? Twice every 5 seconds,....lamp failure, once every 5 seconds,...ballast or thermal fuse failure. You have a lamp, ballast or thermal fuse problem. The ballasts are a discontinued part and can only be purchased used at approx. $225.00 or rebuilt for around $175.00 less any service charges to diagnois and repair.

before a lamp blows it draws more current than it usually uses, but since it uses dc, it couldn't blow the ac fuse. but if the regulators on the ballast or power supply were bad, it would blow the lamp and draw ac power, possibly blowing the fuse.

I changed the lamp of my tv but still dark


The Ballast, or "ballast booster" is sometimes the culprit, gives the same symptom as a burned out lamp. Make sure your main power fuse is not blown first.

Replaced the lamp on 50v710 keeps on burning out


You have a bad Ballast. This can be repaired sometimes by replacing the capacitors on the Ballast circuit board.

New Lamp will not come on


I suspect thermo fuse near lamp or ballast or light engine. In that order , first double check lamp is in tight and covers are on correct there are switches on cover for lamp.

1 thermo 150.00
2 ballast 250;00
3 light engine 600.00

Get a tv service center to come over and check. it would be worth the service call ask him what he charges for road call , at least know you have price and part information.

Vulb,
Having had to change the lamp I would suspect the lamp thermal fuse is open... It's located over the duct for the fan housing and solders into the ballast board.. Check it for continuity and if open replace it..
There are several thermal fuses in that unit and not all of them as easy to access as the lamp one.
Good Luck
Bill
