Question about RCA R56WH76 Projection Television
When you turn on the light green get on, but right away get off
I would like get the blue prints in order to fix. thanks
SOURCE: RCA Projection TV won't turn on
Ok you got you a Rca ITC222 I See ALOT of these things. To start the troubleshooting.. UNPLUG the set for a min of 30 min the plug back up. ( I have never seen this work) If the set stil fails to come on then you have a processor lockup. The first thing you can conclude if the light flashes is it is NOT a FUSE. THe sets processor has determined that a safety condition has occured and shuts it down to prevent further damage and fire. THe top cause of this include Horizontal output trasistor, flyback transformer and high voltage splitter. but There is about 25 different failures that can drive it into shut down. technicains have interface equipment that can read errors codes much like a car.
typical repairs on this set run 150 to 350... if you have to replace tubes...250 per tube +labor which runs 250 ... these set new cost 800 so unless under warrenty.. you got to determine if it is worth it.

Hi, This could be several things as the power goes everywhere. Long distance troubleshooting so hang in there. First try a cold reboot by unplugging and replugging after 30 minutes. If nothing check P1 on the light engine for the following voltages: pin 2 5vdc, pin 3 3.3vdc, pin 9 3.3vdc, pin 12 12vdc. If any of these are not good it is the formatter board. If all are good, does the color wheel spin at all. If this is OK then check J4 on the light engine, the ballast enable line should be 0 vdc in stby, .5 vdc at turn on, and 2.5 to 3.25 vdc in run. If good, is the light engine trying to fire the lamp? If not, inspect the J4 connector and the lamp power supply, If they look OK then the lamp ballast is probably bad. This will give you something to do for now, Good Luck!

Thats the eroor for the flyback and CP150 needing replacement you can get the flyback # 259296 and the CP150 at the following link and they give free step by step instructions on how to do the repair.

first check all fuses they are small, square ,RED and can be confused with the square small caps. the sizzling is prob. the flyback transformer (what the h.v. wires from each tube plugs into) if you are only getting green then tv shuts down or is dead now. i would replace any bad fuses and replace the flyback transformer. also make sure you do a very good visual inspection of all the boards.

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 it should be labeled that right on the board.
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 or you can goto radio shack and get a inline fuse holder and get the smallest glass fuse they have witch is .75amp witch is 500ma and all together cost about $5.00
7 RESOLDER FLYBACK CONNECTIONS or both ends of the inline holder 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'
