Thank you for confirming.
I did not realize initially that you had a CRT (tube based) tv, as I didn't have the model.
This changes the situation, and makes repairs unfeasible. With a newer tv it could have been a simple board.
You have a 10 year old crt tv that is obsolete technology at this point - there are no parts readily available and most shops won't even work on them any longer.
Even with availability of both, it is not practical to repair, as you'd spend several hundred $ to have it fixed, while you could buy a brand new LED tv of this size witha fresh warranty for about $150.
For occasional use in a guest room, it may be fine as-is, but I would not invest further in repairing it.
Depending how you’d like to proceed here, I can help with finding parts, finding a repair shop, or recommending replacement options. Just let me know.
Best regards, ***** ***** for the news,
(Note: I see nothing about a $57 charge, from what I can tell your agreed upon amount for this question was only $28)
