Check the connection of the ground. Bad connection of ground usually create this problem.
Especially the ground connection between the crt board and the wire who surround the picture tube. Let me know what you will get after this.

From your description it sounds like you TV is experiencing a shut down and re-set condition. This is usually caused by some type of voltage irregularity in the power supply section of the TV. Unfortunately, this is not an easy fix and will require a trip to the shop. Get an estimate before approving repair. In the new world of disposable electronics the cost of repair may exceed the value of the set.

Does the model Polaroid TTM-2401 TV have a digital tuner?


Your TV will need a HD converter because it doesn't have a digital tuner but only if you are receiving over the air signals. If you have a cable box or satellite receiver, then you do not need the converter HD box.

Picture turns green!


The CRT (picture tube) is failing. This is classic in these TV sets, and including many models of the Sony.

There is a short occuring in the electron gun. The CRT would not be feasible to replace even if it was available!

The power supply is going in to protection. There is a short somewhere.

Since you sound like you are able to service the set, remove the CRT socket and see if the set starts up and has high voltage. If so, the CRT may have a short in the electron-gun, or it is being over-biased from the CRT board.

I don't know the particular model design of your set. In the models that I do know, I have had components on the CRT board go defective and cause over-biasing of the CRT and cause a shutdown on startup.

Sometimes the components on the CRT board fail because the CRT is at fault, and it is arching some very high voltage back out to the devices on the CRT board. In this case, they will soon fail again.

If the above does not work, then it is possible that the flyback transformer has some shorted turns, or there is a failure in the HV multiplier.

Other things that can cause a shut down is if there is any components in any of the areas of the set that are causing too much current pull from the supply.

These sets can become very involved and a challange for the most experienced of techs to service.
