Count the number of "blink" and then google your make and model. At the end add "blink codes". The number and sequence of the blinks is a self diagnosis for your tv and will tell you what the problem is.
All the ITC222 series will blink 19 if they have a no start situation regardless of the problem, Since the set wont power up the Main eprm cant communicate so it blinks 19 which means it cant identify the chassis. When you press the power to turn it on does the power light come on briefly then go out 3 times? Let me know and I will assist you with the problem. Also do you hear any sounds when the power is pressed?
This sounds like it could be a malfunction in the High Voltage section of the TV. The shutdown circuit is switching on and preventing the TV from turning on. This might be due to an excessive amount of current flow possibly caused by a shorted turn in the Integrated High Voltage Transformer (IHVT), or a shorted Horizontal Output Transistor (HOT). To test this you will have to unplug the TV set, and with a multimeter set to resistance, measure the resistance from the collector of the HOT to ground, If it reads 0 ohms then that is the problem (a shorted HOT). The next test which is of the IHVT is a little difficult because it requires removing the IHVT and doing a ring test. At this point I would like to suggest that you take the TV to a repair shop, because these next test might be difficult for someone who does not know electronics, and if you have no knowledge of electronics you may do more damage then good.
With that being said:
Remove the HV anode of the IHVT connected to the CRT by first using a large flathead screwdriver connected with a clip lead to the ground of the TV, by sliding the screwdriver under the rubber cap and releasing the clips. Then unsolder the pins on the bottom of the IHVT using a soldering iron and a suction type desoldering pump. when the solder is removed , pull the IHVT from the circuit board. locating the main primary winding connect it to the device that you are using to perform your ring test (I use a Sencore LC-102), when it is connected do the ring test and it should have at least 10 rings to be considered good, any less then 10 and the IHVT is to be considered as bad.
