56? packard bell 21" tv scored

The two silver bands confuse me as there should be only one silver band on any resistor to indicate a 10% tolerance (on those resistors that are 10% tolerance only).

If you have or can get a schematic it might be simpler to just look up the resistor in the schematic if the color code is illedgible IMO.

Perhaps Grey, Red, Red, Silver... 8200 ohms 10% ?

well it looks silver red red silver, but maybe one is grey. I ordered the 8200 ohms resistor and ill see if that helps.

Im having another problem i just found out about. With the tv on its side in the stand i built to recap it on, it plays okay, sans the top wavering. when its upright.. only the top 1/4 gets a pic, then that stops, then its a horizontal line which quickly becomes an off centered dot and dissapears.

Ive just.. no clue here guys.

Ive checked and every cap ive done is right.

Any clue what this is? It seems like maybe something is shorting out or touching another thing when it gets put right side up. Frankly this was going so well and now its driving me crazy.

Check carefully for loose bits of solder rolling about the chassis, those can reak all kinds of havok if not removed after solder work has been done.

[jbivy]

so, im borrowing a tube tester tomorrow. i hope its potentially that as i havent found any solder splatter causing a short.

while I haven't seen that before in a resistor, it is common with low-value ones to have silver/gold in the multiplier - e.g. red red silver silver means 22 ohms, x10%, so you have a 2.2 ohm 10% resistor.

Not a perfect example, but it gets the idea across.

[jbivy]

Well the resistor MAY be silver red red grey. But its a bit hard to tell, its crumbling..

If the resistor is still in place I would check it's resistance. It should be close if it is still functioning. Really low ohm resistors in older sets are relatively rare. If they are used they are usually found in the primary B+ supply to prevent inrush failure of the rectifiers (silicon). Seleniums rarely have anything but a fuse resistor to prevent the house from smelling "real foul" when they burn out. What circuit is it in?
I have seen low ohm in the filament of some high voltage rectifier tubes but they are pretty reliable in that application.

If the "waves" are side to side, moving up or down the screen, it may be electrolytic filter capacitors in aluminum cans. I don't recall you mentioning whether you replaced any of them. In particular I would look for a cap wired in series or parallel, in the main B+ circuit, right after the 5U4 rectifier or solid state rectifier if so equipped. A '56 would almost certainly be a tube rectifier.

Hard to tell from your description. Could also be Horizontal sync. Are you able to post pics yet?

Good Luck! Sounds like good progress so far. Nice find!

This thread is almost four years old!

[jbivy]

guess all the pictures id posted, years back, deleted themselves.

but the tv got restored, got a few months of watching time. The crt detonated like a bomb one day last summer, but ive found a new one. It tests a tad low but.. hopefully ill get it back together this year.

but heres a pic of the packard bell.

Glad that you are ok, hope nobody got hurt. This is a beautiful TV.
