Water got spilled on my SONY KV-21VM3MT. Showed it to a local repairer only to know that the system IC got damaged. No parts for this model in the market. What can I do? This is an early 90s TV

SOURCE: part help

the vertical o/p generic number stamped on the fron of the ic is "TDA8172" the sony part number is "8-759-980-58". good luck

Hiii...

My version is :
For safety reason you should replaced them ( Horizontal ic,Vertical ic, Deflection ic) and olso all the big capasitor nearest the ic....that's my version....if you have big budget for it....he..he....

Thank's

I am not familiar with the particular model of Sony TV that you have. I can answer genericaly:

There are a number of voltage regulators typicaly used on TV sets. These are usualy IC devices, or a complete descrete circuit. The purpose of these are to regulate voltages that are used to operate various circuits. Most sets can typicaly have anywhere from about five to maybe even a dozen or more throughout the set, depending on the sophistication of the model.

The regulators, like any part in the set can fail with age and use. Sometimes they are damaged from other components failing, or when a regulator fails, it can damage the circuit areas that it is suppying. When the set is being service, the tech must check for other failed parts.

There should be circuit designations printed on the PC board. Without those, there are too many possibilities to give you anything useful. Can you provide those please?

Thanks,
