Hello why do I have a loud buzzing noise coming from my umc combination 21 inch television so bad you cannot here program dialogue ?


You need to send your TV Model first, but in general any strange sounds in a TV come from the followings:
1- High ripple in the power supply of the sound card.
2- Bad polarized capacitors in the sound card
3- High noise in the main power supply (SMPS)
4- For CRT tv, weak insulation of the Line Transformer
5- An external source near your TV set which is picked by your TV and amplified.

Hello i bought last week the watch bj2000-09e but my question is the orangs hand in the watch is it only for the eco load? i thougt is is for seconds.


The orange hand is called the "function hand" and is not for indicating seconds.

If you haven't got any instructions with your watch you can get them from their web site "citizen.com".

Click on "find a watch" and enter the model details and you watch will appear. Click on the picture of your watch and more details will appear.

On the right you will see "get technical info". Click on this and on the right you can choose a version of the instructions.

My samsung have no pictrue


While only of historical value since both messages are so old, neither of you told us what model set you have. npwds gave us a small clue and even that isn't much use without knowing what kind of set it is.

UNIVERSAL CODE FOR A CITIZEN TV


Unfortunately, the codes you use with a universal remote are specific to that model of remote (it's not like all Citizen TVs are "0105" on every universal remote everywhere for example; the same TV might have a different code on each different model of remote), so we won't be able to give you a specific code to try.

However, you can try doing a "code search". Most models of universal remote allow you to search for the code. It's usually something like entering a special code (like 9998 or 0000) and then repeatedly pressing a button until your TV turns off or changes channel -- when it does, you know you've hit the right code and can stop. Look for instructions on how to do the code search in the manual for your remote.

Picture disappearance & tv turns off


It sure sounds like you have a classic case of bad solder joints. Resolder all the connections on all boards.
