There is some short circuit with the main board of this TV. Contact any experienced service technician to get it repaired. It is a skilled work, that a user can't do.

Hello maymet,

This sounds like the HV protection circuit is cutting off the TV due to a high current event in the set. This could be a problem in the High Voltage section of your TV (Horizontal output transistor, Integrated High Voltage Transformer, and y of the deflection components, and or the CRT in cases of shorts).

I would suggest that if you do not have a background in electronics, you should have an experienced TV technician troubleshoot and repair this problem.
This is due to the nature of the dangerous voltages that are present in the television.

I hope this helps,

Thank you,

Shuttle83

The Channel display will not turn off.


You will need the original remote and press the display button until it says off.

Bummer you don't have the original remote.
You can check out remotes.com and input your model number.

I hope that this helps you out.

Sony Trinitron XBR, Stand By Mode?


Generically, the 6 or 7 blinks usually indicate a problem with the horizontal circuit. In order to provide accurate diagnosis and suggested solutions, the exact model number is needed. Please update this with tha number and I will post more details.

Thanks,
