i have a 1986 sony trinitron color tv, model number kv-20xbr/25xbr. i a trying to set it to channel 3. i recently purchased a radioshack 3-in-1 universal remote, and it seems to be responding to Sony code "0000" (the led light blinks twice after i enter it) but the tv doesn't respond. how can i make my tv go back to channel 3?
When the led blinks twice it is telling you that the remote accepts the code, but that does not mean the tv accepts the code. If the tv does not power on after programming the new code then you must try the next code in the sequence, until you find one that powers on or off the tv.

your converter box has a channel generator for the channel #3 and you tv has a tuner set to ch#3 that and a coax wire . every part of that system has to be working correctly to send video ,color,sound if even one part of the system is a little off you run in to problems . most likely your problem is with the converter box channel generator . contrast that to when you get the signal from your video input . with that simple system you just take video from the video board in the box and send it directly into the video board in the tv .....a lot less to go wrong .
my sont tv model no. KV-XF21M83 (21 in's) indicator lamp flashes red a number of times between 3 secounds interval
the color of the tv has gone faded. The channels name on the top right or left side is not seen properly
The EHT is sparking near the picture tube.
Nessarry guidence may please be comnicated in this regard please. send me feed back to my email adress [email protected]
Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
I dont recognise that model number.
Take a look at the rear of set & see if there is a chassis number eg AE1. AE1A, AE1B, AE1C, AE2, AE2A, AE5, AE3B, BE2, BE2A,BE3, DE1, F1, FX,
These are some of the common older chassis.
You say led flashes does it flash 2, 3, 4, 5, times etc then pause then repeat ?
