Re: wont turn on
Who ever told you this was right the TV has a HV problem and that is why it is shutting down.
I would suggest that you get one of the shops on FixYa.com to take a look at the set for you.
I have worked on a lot of these sets and I can tell you that it will not be cheap.

Possible there is a short within the outputs and so the power is tripping off when switched as a protection since the chances of damage is more. It will require a voltage check on the motherboard to confirm if the +B voltage comes up and fails. If you trace the +B it will lead to the fault condition. In most cases if the switch on is repeated you can notice the heating of a driver or component which can confirm the fault. Once the short or the drain circuit is removed the +B will be stable. Make sure that precaution is taken when testing high voltage circuit.
This could be a couple of issue. 1) Power supply problem. 2) This is a CRT rear screen so it could be a High Voltage issue. Possibly a faulty HOT 'High output Transistor' that supplies the high voltage to the CRT's. Good to get it into a trusted service shop. Blessings, A/V Media Tech Guy
Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.
the rca itc222 chasis has no front led diagnositc codes. Does the led flash imedatly when you plug it up. or does it start when you push the power button. if it does when you first plug it in then you have a problems with what is know as standy voltages. voltages that are always there when you [lug the set in. the processor does not see correct voltages. now if this flashes occur when you oush power button then there is problems with the secondary voltages also known as run supplys. does the set try to turn on do you hear static.. if not then you might have high voltage flyback or horizontal output problems.
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
Hi ,your trouble could be a 2200 35v cap on the high voltage power supply,its in the middle of the board behind a little u shaped heat sink,the cap is green and if its bad the top will be pushed up,hope this helps
