We were watching it, heard a "pop" and smelled burning electronics. The on button works, the power comes on and you can hear the relays coming on like normal, but there's no picture, and the TV shuts itself off after 10 seconds or so. Would this be the High Voltage unit?

Re:
If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.
You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.
good luck!

Sorry bad news these TV's work off of lights that shine thru the back of the screen if you heard a pop it was the power board that turns on those lights not an easy fix sorry.
hi,
Check the lamp of you tv. The lam is burned. that's why you heared a pop up sound and burning smell. Just check it and replace it. you will get the picture back.
ok
replace capactors on mains power board they will have raised tops and look like little batteries with white kine on one side replace with same value e.g (2000.mf 25v) make sure line is on same side take picture to help
Well that pop had something to do with the power components inside the TV frying. I would have to say there is nothing you can do to repair it as its dangerous to work on such things. I wouln't waste my time bringing it to a repair shop they will probably tell you to just buy a new one.
This may be an easy problem to fix. If you heard a pop sound, it's possibly a burnt cap on the powersupply. Check caps C521, C522, C517 or any burnt caps on the RA-3 chassis. Obviously be careful when checking.

1St. need to konw how many times the light bilks, it sould bilk a # of times then a short pause then repeat the # of bilnks again & again. The number of blinks is a an error code to help locate the cause of a fault. it is not allways accurate, but it's usually right. give the # of bliks & i will try to get you into the right circuit.
