Here is what you need, its from the manual for your TV

The TV is locked by anyway. If you wish to get details about how to unlock it, check this link. http://electronicshelponline.blogspot.com/ Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

go into video set up and take tv out of zoom mode

it sounds like you have it set to zoom a standard definition signal and that will make picture become bigger than the screen and cut picture off

hope that helps

Change all the capacitors in and around around the sound output section. Usually Philips capacitors shows a some sort of leak after some years. I says this according my service experience. I'm working with this kind of electonic entertainement equipements since 1974. We cannot predict the exact capacitor poise the problem. That is why recomeds to change all of them. It won't cost so much.

You can demagnetize your TV by using one of the bulk erasers that the Radio shack sells. Start from the middle of the screen, circle the eraser counter clockwise motion all the way to the border of the screen in the pull out position, repeat this procedure for a few times. If the problem is still exist, check the distance of the sub to your TV, must be at least more than 8 feet, if not move that big monster further away from your TV. After you do this and still have the problem, your TV tube is damage and need to be replaced. You will have to consider either to repair or buy a new TV whichever way is more cost effective.

From your description it sounds like you TV is experiencing a shut down and re-set condition. This is usually caused by some type of voltage irregularity in the power supply section of the TV. Unfortunately, this is not an easy fix and will require a trip to the shop. Get an estimate before approving repair. In the new world of disposable electronics the cost of repair may exceed the value of the set.

Yes it can. It can burn the house down if not corrected. That's why, there are laws controlling the installations.
The National Electric Code.

Check the connection of the ground. Bad connection of ground usually create this problem.
Especially the ground connection between the crt board and the wire who surround the picture tube. Let me know what you will get after this.

I checked out the manual for a similar model tv from polaroid...there's only one input for the coax cable from your antenna, so if the antenna's cable is connected to this input, this couldn't be the problem. What I do have trouble with on my own tv is that my indoor antenna location can make huge differences in recognizing all available digital signals. I could even have the antenna facing a different direction, and get different results. There are a few sites you can google for to find your distance from the broadcast towers, too. This might help to determine if you need a stronger antenna. It's a painfully long procedure to try different angles and positions for your antenna each time you run a channel scan, but this might be the only thing that would prevent you from picking up the digitals. I try the highest spot possible, and the one closest to the outdoors. Good luck, I hope you can pick them up soon! (Any antenna works...the industry tries to pass off "digital/hdtv specific antennas" to make a buck. I've used a cheapy rabbit-ears antenna and was able to bring in digital channels, as long as your tv or converter box is converting the signal.)

You TV does not have a built in digital tuner, so is not HD compatible.

Your TV will need a HD converter because it doesn't have a digital tuner but only if you are receiving over the air signals. If you have a cable box or satellite receiver, then you do not need the converter HD box.

To me, sounds like a picture tube issue. horizontal / vertical controls don't fix it. then its dead.

EEEEEEEEh check the power supply, from your power cord , fuse, rectifier bridge diode, whith out forget that the old TV got the bad connection in old solder!!!!

Did you unplug it from the wall. try unplugging if from the wall for two days and try it again.

The CRT (picture tube) is failing. This is classic in these TV sets, and including many models of the Sony.

There is a short occuring in the electron gun. The CRT would not be feasible to replace even if it was available!

What is happening on this set, like others (not necessarily this make and model), is sometimes there are decoupler capacitors in the power supply and the secondary voltage supply from the flyback area that start to go opened in value. This allows some high frequency ripple to get back in to the video processing and CRT drive circuits. You will visualy see this as waves or interference in the picture no matter what you do. The solution is to have the set properly serviced.

You will not be able to fix this set yourself. Proper troubleshooting is required to find and replace the defective parts. There are high voltages in many of the areas where this fault can be occuring. I would suggest to take the set to an experienced service tech to properly fix the fault. Most of the cost will be the labour to do the work.

Considering that this is not a high quality set, you are probably better off to get a new set. I would suggest to stay with the big brand names. You will pay more, but you will get better value and performance for the money spent.

The power supply is going in to protection. There is a short somewhere.

Since you sound like you are able to service the set, remove the CRT socket and see if the set starts up and has high voltage. If so, the CRT may have a short in the electron-gun, or it is being over-biased from the CRT board.

I don't know the particular model design of your set. In the models that I do know, I have had components on the CRT board go defective and cause over-biasing of the CRT and cause a shutdown on startup.

Sometimes the components on the CRT board fail because the CRT is at fault, and it is arching some very high voltage back out to the devices on the CRT board. In this case, they will soon fail again.

If the above does not work, then it is possible that the flyback transformer has some shorted turns, or there is a failure in the HV multiplier.

Other things that can cause a shut down is if there is any components in any of the areas of the set that are causing too much current pull from the supply.

These sets can become very involved and a challange for the most experienced of techs to service.
