TX826
BE SURE TO USE AN ISOLATION TRANSFORMER !!!
THERE ARE POSSIBLE LETHAL VOLTAGES INSIDE!!!
SAMS
3593
3618
3624
3662
3729
3780
3895
3999
DP28-K 1N4004 POWER DIODE part of bridge
This is really earth ground
but the chassis is negative
with the bridge rectifiers
negative leads to chassis
So using chassis as common
there is positive voltage on TP15-C
_RP38 680/2W resistor
__RP39 220/? resistor
___RP40 680/2W
____TP15-C 54.6V be sure to check the configuration on this transistor
_____TP15-E 13.6V source
______TR03-C
_______TR03-E 5V source

Tommy , usually TP11,12, 15, will fix that set. Have the print in paper
only, but will be happy to scan the supply for U if U want it . |

Sir.
I am also having some problems with TV (same model) and I will appreciate any help from you.
Most of all I need a circuit diagram and with a diagram in hand am sure that I can fix the problem..
Can you please help??.

Hi David
I would very much like to chat with you.
my set TX826TB will not start...
looking at the base of the horizontal output Transistor the waveform keep
going on and off at one second intervals.
the hi voltage is doing the same thing.
I don't have a diagram and need your expert help.
thanking you. |
