Where is the battery located , I took off rear cover ( ballasts , lower board ) but no battery !

I just had an issue with my rca hd61lpw42, I had replaced the lamp and got the same five blinks you described. I took out the ballast the smaller circuit board, its in front of the light and mounted to the front of the tv. To get to it you remove the back cover with the tv cooled down and unplugged of coarse. Be extremely careful when removing the ballast as it normally operates at about 336 volts dc. its basically no amps but it will still throw you across the living room. The being said I found another site that discussed our issue on the ballast going bad. It is not the whole board that is bad normally. There is a solder joint in the middle of the circuit board coming up off the bigger board and that solder joint normally goes bad and causes the issue. All I had to do was remove the board and resolder the connection and reinstall. But you can get them on ebay for $50. iif you have the money or no soldering experiance I would suggest that route. The site is http://www.ebay.com/sch/i.html?_trksid=p4712.m570.l1313&_nkw=%09+RCA+Ballast+Assembly+%28261629%29&_sacat=0

Now I hope I can keep the light tunnel together :-)

Hi, if you take off the back cover of the TV. Once you take the cover off there is a metal plate in the middle that has to come off. Behind the metal plate you will see a metal box with holes in it, thats the ballast board. It can be a number of things. It can be the ballast board or the power supply board. Take the back cover off and turn the TV on. You should hear the ballast board trying to fire. It will try at least 3 times before stopping. Is your lamp light on in the front of the TV.
Thanks for using Fixya, If you have any other questions please let me know.

Hi, sorry about that. I hate that to when you buy something and it doesn't fix you problem. It is either your lamp ballast board or your power board. If you take the back cover off and turn your TV on listen to hear if you hear your ballast board fire up. The lamp looking at the back of the TV with the cover off is located to the left side. You should listen there to see if you heat anything and if not then more than likely its your power supply board that probably got zap but a surge.
Thanks for using Fixya and please rate..

Ur tv the Ballast board the help to turn on the tv projection bulb is dead.Try website like Tvrepairworld.com to buy the Ballast board for the replacement.The Samsung/Akai tvs use the same Ballast board.When in the website go to the menu that said Samsung/Akai circuit boards.Pick that option click on it,u will see a picture of a Ballast board look like.

Sounds like the ballast has gone out. Samsung recommends replacing the smps board(power supply board) when you replace the ballast because it is the smps that takes out the ballast. replacing just the ballast ,machine may work ok for a short time but will destroy the new ballast fairly quickly.

1999 GMC Envoy w/ same problem - we removed the bumper then had easy access to the ballast (two bolts on top and one on the bottom if I remember correctly). For the bumper, there are two bolts visible on top, then two a bit lower just inside. Remove the 4 bolts then you pull the bumper forward to unlatch and remove it. When you put the bumper back on, insert the lower bolts first - otherwise it\'s a pain to get them back in correctly. For a temp fix we removed the ignigtor/bulb and ballast, took the wires going into the ballast (regular bulb wires) and connected a 9006 bulb. We removed the retainer from the ignigtor to hold the new bulb into place, it took some adjusting to get it set in place but it worked nicely. We will be putting new/aftermarket headlight assemblies in soon, but this fix only cost $25; it was a quick solution that took about 2 hours.

you either need another Lamp which is very possible or Ballast Board. Ballast board is what turns Lamp on, pull back watch to see if there is a Ark coming from spark cap on Ballast board if so Lamp if not Ballast board call Mats for lamp 1-800-628-1118 OR Go to E-Bay for Lamp and Ballast Board Look under TV Parts After rereading your Post I think Lamp! Samsung OEM Had Alot of defective Lamps and do not hold up!

It could be a issue with the ballast try to check if you have a buzzing sound. if it does is most likely a issue with the ballast (only if sound cames near the lamp) you can check that just follow the cables that are connected to the lamp, take out the back cover of tv, and keep pushing the switch cover (if not tv will not turn ON). and check if that sound comes from the only board connected to lamp. if it does, you are going to need a ballast.

Minor point, the correct term is 'ballast' like on a fluorescent lamp.

Unplug the unit from the wall.

Remove the filter cover (from the rear, it's on the right side of the electronics cover). Remove the electronics cover (the one on the back with the fan in the center). Remove the rear metal plate (about 25 screws). Remove the right rear support bracket to gain access to the ballast area. Remove the ballast shield. Unplug the two connectors on the ballast module. Unscrew the lamp connector (2 screws). Remove the 2 screws holding the ballast in place, they're at the closer end, near the fan. Lift the closer end of the ballast board and remove (there's a hooked lip holding the other end, no screws).

Unit does not have a flywheel. Assemblies include lamp, ballast, color wheel, dmd board, light tunnel, main and/or digital and analog pcb as well as power supply. These are all the assemblies in DLPs. The problem you described is usually lamp or ballast, but can also be from dmd or other circuit boards. Make sure lamp cover door safety switch is secure and fully engaged after replacing lamp or removing rear cover. I admit these sets are not cheap to repair. Good luck, Russmann.
