Wiring diagram for Cocao-Sox Covert Spy Hidden Hat Camera.There are three wires that are attached on the large PC board with a Large IC and next to it there is a smaller IC there is also a heat sink...

Since you have meter, check for this:

Red is mostly used for supply voltage; likely 5VDC.
Black is mostly ground.
Blue is often used for a switched supply line.

Good luck-

My sony rear projection tv's red light started blinking 8 times, so I removed the high vltage splitter, so I needed to test the block. And you guys are sugesting for me to turn on the tv, now do I

Turn on very briefly and make sure the large red wire that entered the block is well away from any metal---if hear a frying sound and blink sequence is gone the block is bad( I used to put the wire into a old soda bottle as it has over 20 thousand volts coming out of it, much like the spark plug wires in a car---high voltage with low current.

High voltage splitter

On the RCA indicated it is located behind the front grill unit under the screen; entire front below screen has to come off and an inspection plate behind that also---splitter is almost dead center behind the inspection plate---one large red wire from rear of set and 3 more red large wires that go to the 3 tubes====block is mostly tan in color but can be other colors.

Power supply sparks when tv is turned on

That can either be the Flyback or the HV splitter. The flyback is located on the lower left hand side when looking in the rear and has a large red cable coming out of its top. The HV splitter is located in the front in the center of the set. These are both very easy and inexspensive to replace. I can post a link where you can get replacements with instructions.If you would like.

Hissing popping sound

It sounds like the flyback or the HV splitter those are the two items that will hiss. It should be coming from the area where the flyback is. thats a large transformer with a large red wire coming out of it going into a Splitter that will have 3 additional large red wires each going to the three CRts. Let me know if you need the part numbers and where to get the parts with free tech support so you can easially install them yourself.

Hi. Quick question.

I am assuming you need to get the HV lead out to remove the board. That model if I am not mistaken has the one large Red HV lead running from the flyback to the HV splitter where the other 3 large wires run to the CRts. If this is the case the trick is to remove the wire from the flyback at the splitter, I have found its easiest to slide the red rubber boot back then use a pair of pliers with tape on the jaws so as to not hurt the wire then grab the wire as close to the splitter block as possible then using a second pair of pliers like a hammer and hit the pliers holding the HV lead and thst will force the HV cable out of the Splitter block.

Try removing the back panel and try to power up the set and see if you can determine if the popping sound is coming from the flyback, in case your not sure what a flyback is it has a large red wire coming out of the top of it. If thats where its coming from let me know as you may need a flyback.

Rca 52" projection tv 3 flashing lights, then powers off

If you see the flyback. That has a large red wire resembling a sparkplug wire. That wire goes into the splitter. There will be 3 more red wires coming from the splitter going to the CRTs. Just take the one wire that goes from the flyback and place that in the glass jar. Now some models have the splitter built into the flyback if thats your vase scenario you will need to replace the flyback. No way to test that properly unless you have a ringer to test it with. let me know how you make out.

Proscan not turning on

Actually, the set has the PTK188AC chassis. This is a very uncommon chassis. The most common reason for the set not starting in that chassis is a shorted high voltage splitter. That is the large black box inside the set that has 5 thick red wires in it. When the set is turned on, the computer senses the short in the high voltage circuits and immediately shuts the set back off. When the set is on, that box has dangerously high voltage in it so it should only be replaced by a qualified tech familiar with the high voltage splitters in RCA projection sets.
