The set is unresponsive to remote or to on-set controls; no raster, located all four fuses, all check good; a/c power is measured after the main fuse... appears to be no filament heat in the CRT...looks like the controls are not activating the power switch...

Re: TV dead; unresponsive, no raster, nothing.
You may have lost the standby power supply. There should be a 5v supply
that runs with the set in standby, see if you can find that. Also check
for B+ (around 160VDC) at the large filter capacitors in the power

You need a new frount control raster for this TV, what has happend is this little circuit board under the buttons has given out. You might have lost the function to control with the remote as well. The best thing to do here is take it to a tv repair shop. and have it looked at.
Diagnosis: bad control raster
Prognosis: replace raster with spare or new

Check for blown fuse EP91. If the fuse is blown, check for a shorted IP01 regulator transistor in the deflection power supply. If that is shorted, change the IP04 photo coupler and leaky D05 a 12 volt zener in the OCP circuit of IP01. If this all looks good, look for an oily fluid on the printed circuit boards under the picture tubes. Good Luck
what kind of universal remote control are you trying to program? most universals have a channel search feature, you need to locate the code or set up key, press and hold the key until the light stays lit, release and press the tv key once, then press the power key continuouslyuntil the tv goes off, stop pressing power when tv goes off and press the enter key once this will leave tv remote set for your tv operation. Not all universal remote the same procedure so you might want to check the web site for the r/c unit you have. please leave pos feedback if i answered your question satisfactorily.
i dont know about a code but i would check my 5 volt standby power supply voltage ,and depending on tv check all standby voltages with set pluged in only .if stand by voltages is good check for horiz drive at base of driver trans when you press the power button
At remote control piece I pressed + button aprox. 4-5 second.Tv started show channels. +button located at buttom right side of remote control piece. Anyway thank you very much for interesting with my problem.
Try these simple trick to find out yor remote control working or not....
Point the remote control towards the Camera of a Mobile Camera
phone,with the camera on. While pressing remote, we can see a light
(Infra Red) coming from its IR LED through the Mobile Camera if the
Remote is working. If the problem with the component that mentioned by you, write down the Number written on that and replace it with the same by the help of a Soldering Iron. Also see the writing near to it for finding out what the component is.... For eg. C=Capacitor, R=Resistor, TR or Q=Transistor, IC=Chip, D=Diode etc.
wepu, Buddy it sounds like you got a power supply problem. As you say the picture is all blue?? With no video or sound and the fact that the channel display is out is the first indication that i would guess this. Do you still have the owners manual that you got when you first got the set? Good, cause thats the only place i can think of where to look in case of service over in your part of the world as I did try!! Man I tryed but to no avail. No one has heard of this model but that dosent mean that it dos'ent exsit!.. If your a tech or know your way around solid state circuitry then you should have no problem finding the fault once you get a service manual from the service location in your owners manual. Now if your not a tech and a handy man ?? If I were you I wouldnt mess with the tv as theres over 25000 volts inside the set and i've seen it make a grown man cry. Man dont attempt the repair or troubleshooting if you dont have the right or proper tools and equipment!!! Good Luck
