Hi,

My RCA 46 RP model# P46770CK/Chassis # PTK169PAAS tv no longer powers up - when power is applied to the unit a small spark is seen to come from directly under the power adapter plug on the motherboard/chassis. The fuse has been tested and is fine. i have used various power outlets with same results. I am at a loss where to look next

It sounds to me that you may have a cold solder joint ( loose connection on the board ). I suggest you remove the board ( or seek professional assistance ) and solder any loose connections that you may find. That may correct the problem. Good Luck.

If it is a "minor" convergence problem you can adjust it by going to the menu and scrolling to convergence and follow prompts A cross will appear when you have reached the correct place and you do the minor adjustments as it says. If picture is bowed you have major convergence problems.

Check Cr4503 in the vertical circuit for short or leaking. The convergence circuit is most likely fine. Also check for any leaky electrolytic caps in the 500 block. (example) CR4503 will be printed on the PCB as CR503. The vertical circuit is located in the center of the chassis behind the big aluminum heat sink.

Dir TV projection Techcions, I own RCA Model:P52937 Chassis No.PTK195M26B. After a big flood here in Chicago, my basement got flooded and my projection TV was in water up to 1 foot. Befor I turned it on, I dreid it out perfectly, then, I turned it on, and a couple components from the power supply got burned up to the point where I am not able to read the part numbers that are on it. I was wondering if you have this kind of chassis and model service manual for this projection TV, or conponet part number i location 101 on mother boatd power supply. Thank you in advance, Darius If you prefeer, you may call my cell phone: 773-875-3926
