1997 Model have sound but no picture

A bit like saying my car will not start, if no brightness, set could be shutting the picture tubes in a older projection set down (if it detects no vertical or horizontal sweep).
about the only easy thing (a brand and model might help) would be if the filament voltage that goes to all three tubes in older projection sets is missing.......

How to check filament in tv

If it has a picture tube first look with set on, three tiny filaments will be lit if good, not real bright as 6.3 volts ac voltage across two pins on the actual tube.

If you can see them lit they are ok---most sets mark them on the board at the end of the neck for the picture tube with H for heater.

Very carefully as high voltages on the board measure for 6.3 volts AC across those pins. If for example its 3 volts that is too low and the voltage from those pins can be physically traced back to the High voltage transformer creates it off two pins.

less than 12 connections between source and the board on the tube, if missing voltage at the tube follow it back--a single cracked or bad solder connection can cause this.

Black screen but still here shows

only about two possible reasons bad solder connections or the picture tube is not getting the 6.3 volts for the filaments in the neck of the picture tube.

If set is opened carefully and turned on look to see if 3 faint filaments are lit or not. If not that is your problem.

Sound but no picture

This is listed as the standard Television and if not let me know--it means it has a picture tube and is not a LCD or other type of set.

Answer is in that case someone needs to "look" inside at the neck of the picture tube with the set turned on---set should have 3 dim lights in the neck of the tube ---filaments like a light bulb---question is are the filaments lit or not?

Good sound no picture

A older set------look to see if display comes on (channel number or menu) if not someone has to look to see if the filaments in the three picture tubes are lit or not.

Several voltages : High voltage, screen voltage, filament voltage all go to the picture tubes.

Sonykv32s20 screen wont turn on, stays dark, but sound works

Its a older set, if you are able to open safely and run set JUST look to see if the faint filaments in the neck of the picture tube are lit, 6.3 volt filaments, and if they are not somewhere between source at High voltage transformer up to the PC board and socket at end of tube neck you have either a broken/bad solder connection or a open part--only about a dozen connections/parts between the two----set will have a ground and a voltage source at both ends of this chain, a bad solder connection will do this if filaments not lit(3 of them in neck of tube).

CRT no image, sound ok. What could cause this?

WE can presume if static electricity on screen you have high voltage (most sets will not have sound if no high voltage).

If voltages appear to get good:

TAKE A CLOSE LOOK IN THE NECK OF THE PICTURE TUBE: all these sets the filaments in the tube should be lit when the set is on.

All are 6.3 volts AC (two filament pins on crt board--one is the ground and the other the AC--use that ground and carefully.

If no filaments or very very dim (they will be hard to see) the source for the voltage (if no or low filaments) comes from the high voltage transformer to the crt----usually one of two issues in this case---a part has opened or gone way up in value (resistor?)

It is a very simple circuit---just follow it back as usually on board that plugs to crt you will see something like H1 and H2. Follow both back and look for a broken connection or an open part between the tube and the source.

Let me know what you find and ask if more questions.

Sounds could be heared upon switching on of the set but the screen has no raster (means total blackout as if the unit were off. a small red LED located @ the front panel continuously blinks just like the...

Since you said the the pictur tube is glowing, your EHT system is OK.
After selecting a channel if sound is alright the TV up to signal
detection is working OK.

The problem now could be in video amplifier circuits. Check the grid
voltages of the picture tube.
Or switch off TV, and check the resistance values of the resistors
connected to the picture tube pins. Replace the defective resistor.

Check after removing one end of the resitor as it will misguide you if in circuit.

Is there a study that not turning your tv off (older model)Sony trinitron will make it last longer ???? my email is please help me find the answer

Most projections have a removable speaker cover on the front under the screen. Then there is an access panel that you remove the CRT sockets are the circuit boards attached to the CRTs
