My UN55EH6000 is doing the exact same thing. Have not figured out a solution either. Have checked for overheating but none apparent.

Reformulate you question to undesrstand it.
I understand that you want to change the Firmware of your
Lcd tv model TLCD-37fhda because it makes loud sound when put on/off. Now, that makes not much sense to me

Use two part expoxy resin. Most have a threaded rod with a hole in the centre for the wire with two nuts and locking washers. You can buy those.

Here is a question that we see often.

Question: I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?
So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour.

RCA DRC8320N DVD Recorder/VCR

Symptoms:

Seems to have no power, no lights on front lit, if listened to closely one may hear a "click click click" sound.

Solution: Replace C232 on power supply board.

Additional technical info:

In this design, the switching power supply feedback is from the 5 volt standby rail only, which is odd. The problem is caused when C232, the first filter capacitor in this rail and the sampling point for the feedback circuit, opens. The clicking sound is transformer rattle as the power supply restarts repeatedly.

take it to a service centre. They will diagnose the component or board that has failed. You can buy boards off eBay, but many are stripped out of broken sets. You can't return them, and a lot are DOA.
