Sony Trinitron Model KV 20M20

This tv had earphones plugged into the earphone jack in the front of the set. Now they have been removed, the tv has no sound. When I push the volume hi/lo selector on the front of the tv, it changes the channel. Would the sound have had to been turned off in order for the earphones to work?

No sound for earphone, there are no rca jacks, the earphone is used to attach speakers, but there is no sound from the earphone jack

if their is a sound from the internal speaker then the problem is with in only in the earphone jack or in the connection. to access the internal part of the tv you need to remove the rear cover. locate the earphone jack terminal re soldered and check the connection at the board ( PCB). you can check also the continuity, attached powered pc speaker then use an analog tester and check weather their is a connection coming from the stereo input jack going to the terminal of the earphone jack of the tv. if no connection replace with new earphone jack. good luck hope this can helped.

Describe your FD Trinitron WEGA KV-32FS120 32" TV Problem i have a sony trinitron kv32fx68e and all of a sudden it wouldnt turn on. the red standby light just keeps flashishing. what could be the...

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

Check for tips to check the SMPS unit:

How to set the channels on a Sony KV-20M20 TV without the remote

Buy a universal remote at WalMart for $10 and set the code to your TV according to the chart that comes with the remote. Most functions of your original remote should work if the code is correct. Sony - TV - try all listed codes on the chart, one of them should be able to control the TV. Check at local thrift store (Goodwill).

Sony Trinitron KV 20M20- won't turn on-dead.

First check the fuse in the plug, if thats good there is a small fuse on the tranformer board inside the television, to gain access to this you will have to take the back cover off, be carsfull not to touch any of the componants inside, it is held on by a few screws normally 3 at the top, 2 on each side and 2 at the bottem, have a route around you should find them, undo them and ease the back cover off, inside follow the power cord to the power board, and you should find the fuse, unpop from the fuse holder. Take to your local electrical appliance repair shop, they should have the fuses there, they dont cost very much at all and they might even give a fuse free of charge. hope this helps.

Sony Trinitron, KV-20M20, cannot access most cable TV channels??

It may be that the tuner is bad. It works in bands and can lose upper bands. If you use a top of set box for cable it may need reset.
