Wont do anything,,i have checked power in to the board and the fuse,,i dont even get the flashing light on the front panel. its a 52 inch rca model # d52w15byx1 hdtv. i sure would like to get this working and learn a little something about it along the way.
thanks very much for any help you can give me.......rowe.

Re: rca big screen, no power light,, dead!
Ck capacitor cp150 2200uf 16 volts if bad 2 more in same circuit also needs to be replaced 220uf 35v.ck second ribbon connector on deflection board make sure it is in correctly,or set will not come on.

FL231. FUSE.... The RCA ITC222 chasis has a common problem. and it not all that difficult to repair. Does your rca projection tv have read blue and green shadows? Does it have bowing in affect on the top and bottom of picture? when you turn it on does some thin red green and blue line bow in from the top then go away. The main question to determine if you have the fl231 fuse problem is if you go into customer menu then setup do you have the "CONVERGENCE' option. If you do not. then i suspect you have this problem. In the manufactering of these sets Lead free solder is used. now there is great debate over the use of lead free. connection tend to be more brittle. cracks develop around the solder connections of the high voltage flyback transformer. this very small crack set up oscillations in the cuicit with a 400 milliamp fuse. THis fuse cant take it. When this fuse blows the processor then does not know its a projection tv with three projection tubes. it thinks its a crt tube tv. and crt tube tv dont need "convergence" so it removes the convergence from the set.
TO REPAIR... 1. Warning. this set can generate leathal dangerous voltages even unplug do not attempt if you have no experence with electronics. 2. Remove the back. there a number of torx 20 screws. 3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse. 4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes. 5 when you get the tray up the bottom side of the board can be accessed you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace 6. REPLACE FUSE RCA PART 259213 7 RESOLDER FLYBACK CONNECTIONS simply heat up and add a little solder 8 reassemble set. make sure you examine the set for loose connections. 9 and remember "BE Careful'
Take the tv apart.The tv power supply board,that the board,have power a/c cord plug into it.That the power supply board,check component parts like capacitors,see if it leaking gases,these capacitors are dead.Capacitors they'll alway bulges up on it tops or puff up on it tops.Have tools like soldering iron and solders?Know basic electronic and soldering?Replaced these dead capacitors will get power to ur tv back.Or tries websites like Shopjkimmy.com to buy a whole refurbish power supply board for the replacement.
The whole dawn power supply board is shorted and dead.U have the equipments,a good trouble shooting and electronic skills,trouble shoot all those transformers out put,check all the primary and secondary out put of those coils of those power transformers?Some of those power tranformers are dead needed replacement.Or try website like Tvrepairworld.com to buy a whole refurbish power supply board for the replacement
Check the fuse on the AC filter board. If you trace the power cord into where it plugs in on the small skinny board located on the right side when looking in the rear there is a fuse on that board. If its completely dead I would suspect that fuse.
Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.
If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.
Usually when devices power themselves off like that, there's something wrong...
ok completly dead with no lights. this is indication of certain cuircit power loss. the main procesor is not receiving power. If i had it in my shop i would TRack the power. or backtrack the ac from the cord comes in through the courd and through the main fuse. then is converted to dc. 360 volts thats wherei would start. Now this is converted to 5, 3, and 7 volts. with regulators. which could be what was mention. I would recomend another tech. WARNING this set can hold that 360 volts even unpluged
It sounds like you may have a bad Horizontal Output Transistor (HOT)
and/or a bad Flyback Transformer. The set is trying to start as
indicated by the flashing light, but an internal fault is shutting it
down right away. It could also be the Power Supply circuit. A
32in. set is not cheap to replace so it may be worth finding a repair
technitian and at least getting a quote. The Flyback is the most
expensive part, the others are minimal. If it is one of the above
problems it could easily be repaired by a qualified technitian.
