Question about Philips 28PW6506 28" TV

1 Answer

Philips 28PW6506 Hi, recently my tv was making funny noises, like a squealing. The picture starts to dissappear with a horizontal line. When i switch the set on now i get no power to the tube, but a component near the front of the chassis board is making the squealin noise. The noise goes up and down, once the power is switched off it sounds like it is being drained...Any help would be much appreciated............Jason

This sounds like one of the capacitors has dried out. They are metal cylinders containing 2 rolled up strips of foil separated by a gel. Over time the gel can dry out an eventually the strips of foil touch creating a short circuit. A TV repair shop should be able to replace the faulty component relatively easily. I wouldn't recommend trying to do this yourself unless you are very confident you know what you are doing, the voltages present in a CRT TV are very dangerous.

Switched from cable to satellite via hdmi cable. Now there are scrolling jagged horizontal lines and no audio.

try running the auto tune program in the set as what you describe may be out of tune for the stations

Sony 32" tv makes a squealing noise, the picture goes to a horizontal line, then goes away with the squealing noise continuing. Turning it off and on again resets it temporarily.

The power supply regulator board should be checked. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy.

5 year old goodmans tv suddenly went off, then intermittent high pitched squealing noises

Check the horizontal output section circuit. It sounds that the LOT {Line Output Transformer} has damaged.

My tv makes 3 even high pitched squeals when i turn it on. about 1 second each, then powers off. No picture no sound. All imputs. What do you have for suggestions on what it could be.

One of most two common reason why your set will not come on, is because it has lost the high voltage, the first thing to check is your horizontal output transistor, to see if it is shorted, it will be located bay the flyback, mounted on a metal heat sink. That is what is causing a squealing noise.

High pitch

I have never heard a tube make noise when there is a good picture. Anyway, the noise has to be a transformer ringing or oscilating. They make a high pitched squeal when they have a loose winding or their cover is loose. You probably won't be able to feel or see anything loose on these transformers The power supply switching transformer is the first to look at. Take a hot glue gun and just cover the thing...especially at the base of it. The next (and only other) one is the horizontal drive transformer.It is located close to the high voltage transformer( biggest thing on board and usually in back or corner of the PCB.This one wont squeal) The horizontal drive transformer is about the size of a large marble and is encased in a black plastic cover. Cover it with hot glue also.
If you take the back off you will probably be able to localize where the squeal is coming from. You will probably need a signal to hear the noise also. After you find where it is coming from UNPLUG the set before doing any hot gluing!!!!
If you 're not up to this procedure take it to a technician. Your tube is not going bad and the set is definitly worth repair. Simple fix!! Good Luck!!

CTR Television will not power up

What has happened is that the horizontal output transistor has shorted. The squeal you hear is the power supply running under a heavy load. The picture narrowing or being distorted indicate that the horizontal output was not operating clean. Something in the output section was not as it should be. Possible short in the output transformer/tripler unit or something loading down the secondary voltages generated by the horizontal output. You will need a tech to figure this out....If you are not a tech, then this ones a goner as far as fix it at home goes.....If you are a tech I might be able to talk you through the repair. Have someone remove the horizontal output transistor and I bet the squeal goes away.

My rca tru flat is NFG

The high-pitched squeal usually indicates that the horizontal drive circuit has failed as a result of a dead line-output transistor. This symptom indicates that the control circuit of the main power supply is trying to over-compensate for a greater than usual secondary current. Certainly, an inspection of the line-output transistor will show that it's most likely dead. Sometimes instead of the squeal you will hear hiccups instead. Focus your attention on the horizontal circuit.
