Tv picture fade in and out then cut off.

you may have a loose plug or a bad cap in power supply may need service unless you have tec skills if so check youtube .
try reset maybe at www.proscsnvideo.com

i used to be a tv technician.it sounds like an intermitent fault,which only does it sometimes.most likely cause is dry joints on circuit board,which is faded or discoloureded solder.try resoldering dry joints ,faded or discoloured solder on circuit board.as its an intermitent problem so it sounds like dry joints on circuit board which is faded solder,which means only half of the current is passing through the circuit..resoldering will allow the full current to go through circuit.

Thats a deflection problem which is causing the CRTs to shut down during deflection loss. The deflection board will need replacement. You can get replacement deflection boards from www.tvrepairworld.com

daer user ,

its system board is faulty oor rusty.kindly check the both things

the small signal board is usually the cause of that symptom. You can get a replacement signal board from www.tvrepairworld.com

You have a high voltage leak, one of the three crt's are arching to the metal chassis, this will cause momentary high voltage loss so your picture will fade until the voltage builds back up again.

Repairing this is hazardous because the voltage in the crt's are around 30,000 volts even with the tv unplugged. I don't suggest doing this yourself.

A technician will do the following he will attempt to stop the leak with specially formulated silicone compounds, If this fails the only alternative is to replace the picture tube that is defective.

The cost of repair depends on if the tube will have to be replaced, the initial repair using silicone should not run more than the standard service call rate for the company servicing the unit. If it is picture tube the cost could be upwards of $400.00

Likely to be the STK convergence chips causing a protection circuit to cut in and switch the TV off when turned on. Do you hear clicking when you switch on?

if it is a tube type unit you may not find a new tube they are almost extinct ,
also, most tube malfunctions are caused by improper voltage, only a qualified tech should work on the high voltage section of a tube tv,,, it can kill you even if it has Not Been Plugged in for a whole year

re-post with the make and model number for further assistance

Play sound but screen is black

When your TV cuts off, does just the video cut off or do you lose all power? Does the power light stay on? If the power light goes out, I would suspect a bad solder connection in the power supply, or maybe a defective capacitor or two in the regulation circuits. If just the video is going to black screen, it could be your picture tube getting weak and the cathode current monitoring circuit is kicking in preventing you from seeing a sub-par picture. Sometimes this can be temporarily adjusted out by a very small amount of tweaking of the screen control located on the CRT drive board, but it is easy to get a shock and hurt yourself if you're not familar with the set. The CRT can sometimes be restored for a bit more life with a CRT tester/rejuvinator that the service Tech has access to if that is what is causing your symptoms.
