Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you.
Please make sure to connect the chromecast directly to a wall power adapter, rather than to a usb port on the tv.
Not the the tv usb, a power outlet.
Then set the tv hdmi input, and it should work form there.
Note though that this is a very old tv and lower resolution, so it won't support some content through the chromecast.
The default output of the chromecast may prevent it from being compatible at all.
If you aren't getting anything still, the hdcp connection between the chromecast and tv isn't detected, meaning the tv is too old for the cast to recognize.
Not directly, no. For the same reasons, that tv is too old to support the MHL connection.
That set is also double its service life at this point and realistically will fail any day now, so you are really best off just replacing it.
You'll have the same issues related to hdcp and hdmi communication.
Because you have/had something connected to the usb port, which the tv is not going to support.
Unfortunately there is likely damage to the tv at this point from connecting the chromecast, as the usb can draw too much power and fry the motherboard. Try unplugging power to the tv for 5 minutes please, and see how it works from there.
If that doesn't help, it would confirm internal damage, and at that point you really have no choice but to replace the tv. It is not economically repairable.
Again it would be the main board, no they are not readily available or worth fixing.
No, there is a part number printed on the original, you'd have to open up the tv to get an exact match as there are different versions. Again, I would not consider it worth fixing.
You're very welcome and have a nice day,
