1997 model, have you tried the hard reset?

I have the same problem have ypu figured it out yet?

yes,But might not get HD,like a LCD tv.

Hi.

The clicking noise and the TV remaining in standby indicate the the unit is on protect mode.

This happens when an internal fault is detected.

Since there is no indication that the PSU is faulty, more parts must be tested. The Flyback transformer is commonly failing.If there is trace of burning, test and eventually replace the flyback.

Part number is # 334P246060 , here the part: 334P246060.

Regards.

Disconnect all the cables from the TV then connect the power cord from the TV to different functional wall outlet to check if the TV is powering ON. If the TV is not showing any sign of power then press and hold the power button on the TV for 30 seconds to discharge all the capacitors that may be causing the issue.

If the TV is not powering ON even after performing all the above steps then the capacitors on the power board are burnt out and requires to be replaced.

hello do you mean the glass fuse inside, if ok then the components inside will need to be checked

shaun

yes there is a lamp in the unit

could just be a convergence issue. there should be an auto-convergence feature in the menu. outside of that, you'll have to manually converge the colors seperately (also a feature in the menu).

On the service manual you find a convergence setup procedure, did you do that?

i would think it is going to be the main fuse, open the back of the tv, you will see where the power cord is connected to the board, there will be a glass fuse next to it, you will be able to see if it is bad,----make sure you unplug the tv befor you mess with it

i think you need to replace the IC convergence modules..

Your convergence ICs are bad STK392-110 you can get new ones for about 10.00 each. They are located on the left side of your chassis a large heat sink. They will need to be soldered in. Also check the resistors right next t the heat sink. Sometimes 1 or 2 of them go out along with the ICs.

Are you talking about the clear protector screen on the outside of the TV set?

The lamp is not enabled possibly due to the colour wheel motor not turning. Any broken glass jamming it? Or the lamp ballast has failed due to an old/worn lamp.
