Have you tried cleaning the projection bulb. You open the side panel on the left hand side then take a electronics aresol dust cleaning can (like you clean computers with) then you spray it at the light bulb. If that's not it don't worry you won't do any harm to it.

I believe those objects are really black, and always there, Maybe they are no so big as they look, but the projection make them looks that big. some times the plastic use in the manufacturing is not cleaned and those plastics felt in the lenses, being positive. an expert can decide if it is just and object or anything else.

Picture is warped. rca 52 inch model p52929


This is hte beginning of a convergence problem. If you can solder, try resoldering the pins on the convergence ICs. These are large black ICs attached to a heat sink and will be marked STKxxx. If that fails to resolve the problem, replace the ICs.

Keep us posted.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
