1) you must repair the ant cable, see if the cable is open or break test with VOM, this can produce erratic problem. 2) you have the options to go to the repair shop TV for fix.3) clean the contacts antenna TV, for dust, dirty or oxide.4) repair any broken wires and solder.5) of course you have the probably problem of some problem inside of TV example, TUNER, i-f,video detector, AGC. test it see the diagramGod bless you

It sounds like you are describing high-voltage (HV) shutdown. As a safety feature, if the voltage in the TV rises above a set limit, the TV will shut off to prevent possible x-rays from the picture tube. The only way to reset the shutdown is by unplugging the TV, then reconnecting the power.

This shutdown can be caused by several things. The power supply may in fact not be regulating the voltage properly because of component failure. Your power line voltage may be a little higher than usual and causing nuisance shutdowns. Or the HV shutdown control may simply need to readjusted because components have aged and changed value slightly, also causing nuisance shutdown. The HV transformer may be defective, or the picture tube is going bad.

Unfortunately, it's not possible to say what's wrong without seeing the set to check operation and determine the cause. So I can't suggest anything you might do yourself to fix this. If you want to keep this TV you should let a professional servicer check it over, determine what's needed and give you an estimate. Or you can use this as an excuse to purchase a new TV. Flat screen sets are quite reasonably priced now, and depending on what turns out to be wrong with your TV, it might be more economical to replace it.

ihave the red light on at the bottom but nos sound or picture

No, your picture tube is fine. This is a problem in the vertical circuit that deflects the beam up and down. This repair is fairly typical across most television brands and should not cost too much to fix. I don't want to quote another shops pricing but from us this would run about $150.00 to fix.

In some TV's closed captioning can cause this problem. turn off CC and see if that helps.

loocks like green gun in the crt is shorted.

You need to go to the menu screen where the contrass, color etc are located. Scroll each option and one of them will add the color, one of them is probably at 0 so you need to ensure that it's added

that sound is comming from the tube anode it is leaking you have to discharge the high voltage from the anode cap,then take off the cap clean the area with alcohol and put some red or clear silicone on the cap and anode connection replace back the cap on the tube leave to dry for about half hour,this will remedy your problem,no more static.good luck.

try to press channel button on your tv set.

IO board has bad solder joints or is bad if you tap the outside firmly it will come on for a while

Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...

If the trouble is black and white looseboard in CRYSTAL. Loose need to resolder.

Yes, you should still have sound, providing that you have an antenna connected and are tuned to a channel. If you have a vcr or dvd player to hook up to it try that and see if you have sound.
No sound while viewing a tuned in channel or via a vcr/dvd player is not a good sign. It may have cracked the PCB inside the tv. A cracked PCB, depending on the severity, can also be repaired.
You really won't know the severity of any internal damage until it is opened up and checked over.
Is the line on the screen Horizontal (left to right) or Vertical (up and down) and is it centered on the screen? A vertical line would indicate that it may be a cracked PCB (Printed Circuit Board).

If it has a white line across the middle then it is probably repairable.
If the screen was cracked it could, but probably wouldn't work at all, not even a white line. The white line indicates that the vertical deflection IC has failed. Generally these IC are inexpensive and should only take an hour, if that, to replace. A good technitian should be able to repair it at a reasonable cost as well as check it over for other common problem areas.

If the glass picture tube is cracked it is not repairable. In some cases it would be possible that the tv would still work if it has a cracked glass but it would not be advisable to use it as it could allow x-ray radiation to escape. The tube is a vacuum and a cracked tube would lose it's vacuum (**** air inside) and cause it to instantly burn out when turned on. Sorry :(

 

 

•  this cracking on my tv. It cracks and makes lots of noises

 

• it sounds me that your speaker paper cone has become hard or paper has damaged. so best remedy is to change speaker.
• if it is ok then replace all electrolytic  capacitors in audio output section.
• check supply to ic or ic.
• hope this will help.

 

I know one code please try if it helps 1 press mute button once on remote control handset. 2 once again press &HOLD remote hand set mute button. 3 while keeping mute button pressed press menu button on tv set. good luck
