Wei Ya C3129DS chassis not working

Post by TwinX »

Hi managed to get my hands on a c3129ds chassis.

However it does not work. The chassis looks brand nee but was sold as is.

The issue is the following:

When powered the relais ( i think RL1) clicks unstoppable with approx 1 click per second.

Also there is no nek glow.

I do hear a very faint high pitch sound as i am used from crts.

Where should i start troubleshooting?

Sorry no fix, but I have the same issue with an also brandnew 3129A. Nobody I've contacted is willing to repair it, so I hope somebody here will be able to help out here.

Hmm that does not sound very promissing then.

Have you tried anything yet?
We could collect this.

If noone is willing to repair i will start messing around with it as it is useless now anyway.

I would check supply voltage of the relais to see if the problem is with the voltage supply or the relais. Sounds to me like the supply voltage is beeing build up and then dropped, repeating again and again. If it´is the voltage, look were the voltage is coming from and check those parts.
In case the voltage supply is in range and steady, remove the relais and test it with an external power supply unit. Exchange the relais in case its faulty.
