Quatro CTV-7230 TXT-S Repair

[Vince56]

I have a CRT Quadro who will not turn on. Signal red LED works, but there is no picture or sound. I do not know where to start to repair. If anyone knows what to do please tell. Greetings from Croatia .

I don't know what is wrong, but you should be aware that you can get a high voltage shock from a CRT even if it is not plugged in. The charge can remain in the CRT for a very long time after being unplugged. If you touch the wrong part you are going to have a bad time.

I am aware of high voltage parts, and take care to avoid them. By the way capacitors do not look bloated or burned.

There is a very weak sound. Similar whimpering inductors.
