This sounds like the front panel assembly(FPA) switches are acting up. What happens with this model is the FPA switches start to conduct just as if someone was pressing the buttons. This in effect locks up the system control or causes it to do erratic things.
The way to determine if the FPA is bad is to remove it by unplugging from set. This requires front panel disasembly. Note:The remote will still work with the FPA removed so the set can be tested.
Let me know if you need more help or info.

Could be a bad buffer/amp or bad tuner, depending on source selected....accordianman

Try turning down your Red CRT.

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. The noise is what gives it away. This happens so that no further damage, and possible fire will occur.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Does the led blink

If this is a combo unit (TV with DVD built in) you need the original remote---Universals almost always are missing key features the original remote had as most companies have someone else make the unit and put their name on it.

no sound

do you see thin curved blue lines going from bottomto top of screen. If so its most likley a blue CRT drive board issue. If its a solid blue it could be a small signal board issue.

Hello
I can,t understand the fault of your TV with this short description. Will you please inform me some more details of the fault? What do you mean by this "image tears" and "inverted colour". Please give me some more explanations. OK.

You have bad grounds on the power board. The first place are the solder connections under neath the flyback transformer. This is my first area of inspections. You must really, really inspect the rest of the board. This TV has many poor solder connections too numerous to pin point. These are very small and will take an extremely close inspection. I cannot say enough here. Look for bad solder grounds on the vertical IC (do not use excess solder or you will short this IC). Look for solder connections on transistors, diodes, jumpers, power resistors and capacitors. Capacitors include electrolytic, disks and safety capacitors.Resolder other transformers too. Be sure to check close for bad solder connections on the heat sinks as well. Next, use an ESR meter to check all your electrolytic capacitors.This is a good place to start repairs. Thanks for asking and show a few hands of support!

If there is not one in back, it could have the old style DVI jack. You'll need a DVI to HDMI adaptor.
