Chosen Solution

Toddler sprayed (drowned!!) Samsung TV screen with antibac spray so wiped it and thought nothing more. Turned it on that afternoon and screen had lots of lines, very distorted, impossible to watch. Took a cool hairdryer to it and actually has made a big difference but we are left with a grey column (blue and green line either side). It is there on every input except when on ‘no signal’ screen which appears normal. Thanks in advance.

It sounds like the screen is damaged and the only way to fix it is to replace the screen. The problem is I have not been able to find replacement screens for TVs. The replacement screen costs more than a new tv. I would buy a new tv. And for future reference, never spray any cleaner on the screen even water. Spray it on the the rag but don’t soak it and then wipe the screen.
