Question about Philips TP3681C 36" TV

TV will not turn on.

Techman responded to another post stating that it probably was not the picture tube. He asked for more info. Since I have the same problem for the same TV and it definitly is not the TV power cord or the socket, etc. I thought I would give you : The chassis number: 36D7007570 The model number: TP3682C101 The serial number: 14430134 My son says that he can here a high pitch noise when the TV is plugged in. He can hear it, but I cannot! When the TV is plugged in, the back does not get warm. Is there anything else you need? Please let me know if you can help. Thank you.

A high pitched whine is most of the time the power supply trying to run, but it is being loaded down from a short somewheres in the set. Sometimes a resistor on the CRT board will open and make the set shut down right after start up, sometimes the horizontal output transistor causes this problem, almost any circuit for that matter can cause this problem. Good Luck

LG Golden Eye CRT not working as it was fell down from Table what may be the probable reasons?

If the picture tube neck has got any crack, the TV wont switch ON. Check it. If the circuit board inside have cracked, the TV won't switch ON. Your TV need a through check up. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

If you are comfortable working inside the set, I can suggest the following:

1) Open up the back and locate the flyback transformer (part with large red wire coming out the top). There should be 2 adjustment posts on the back of it.

2) adjust the top one slightly clockwise as you are facing ht back of the TV. This should cause the overall picture to brighten. Don't turn it too much as you will then see the "retrace" lines.

3) Adjust the lower one to focus the picture.

That should help a bit. If not, then the picture tube is probably at the end of its life. Keep me posted with your results.

The set you have has a bad tuner assembly. At this point most likely you would be better off getting a new TV set. Good Luck

TV has audio sound and no picture

Your set migbe missing the high voltage that lights up the picture tube,you need to check for loose conections starting at the horizontal drive transistor and transformer ,then check the horizontal output transistor for short,it needs to be checked with a meter if the output is shorted it probably open a safey fuse or resistor to prevent more damage.If you are familiar with tv service this will give a place to star but if you are not too familiar be safe and seek the help of a servicer.Let Us know if you need more information.

I could be wrong, but, from your description it looks like a cold solder, most probably in the Filament Heater circuit. If you are well versed in Solid State Electronics, I suggest you look for a loose solder or joint. Shut OFF the TV, Open the rear cover and chech for any dry dolder or loose coonections. Start with the CRT Neck PCB. Follow the tracks from the two Heater Pins (Marked H H) on the base). Also, gently remove the Neck PCB gently from the Picture tube, and (very carefully, mind you!) clean the Picture tube Contact Pins. Again, very slowly and gently, replace the PCB. Try your TV again. Let me know if the problem is solved. As for the second problem, ( less brightness) how old is your TV? Over time the emission from the Picture tube Electrodes becomes less, and picture quality detoriates. If set is over 6-7 yrs old, or if you are a heavy user - that is, you have your TV switched on for 6-8 hours a day, it is time to go for a trade-in. But, if you are very attached to the TV, you can always take it to a service shop, where they will re-condition the Picture Tube for a modest amount. It's life will get extended by a couple of years.

TV wont come on

Most likely cause would be a blown fuse on the power supply if you are getting no lights on the front, no response from the buttons, and no warmth from the back of the set. First check that not only is the power socket in the wall working, but also that the plug on the TV power cord is not faulty or distorted so it doesn't make the circuit when plugged into the wall, also if it has a fused plug, check that. Then if you feel up to taking the cover off, make sure the set is unplugged and leave it for a few minutes first. take off the back cover (usually a few screws around the base of the set, but it should be obvious) follow where the power cord enters the box, and about the first thing it should connect to is likely to have a fuse. Probably a couple of metal spring clips with a glass tube type fuse sitting in them. The fuse should have a rating stamped on it and you should be able to get a replacement at most hardware stores, but make sure you get the same type as well as rating. If a replacement fuse doesn't cure the problem then the next thing to suspect would be the transformer and rectifier circuit - the fuse should have protected these, but sometimes it doesn't work that way. If you need help checking these then please ask again, but I suspect the fuse is your problem. Hope this helps you out, please ask again if you need more info :)
