Universal remote code
Almost any Sony TV remote should work for this set--if trying for a universal Google the model number of the Remote for "manual" which will have instructions and a list of codes to try.

KV-DZ29M61 crt green light blinks
Its HOT [Horizontal Output Transofrmer] section circuits has the trouble. There are two possibilities for this fault. The first one is shorted HOT itsef. It can be replaced; and can be bought from most of the electronic sparepart shops at your town. It will have a number printed on it, and should benoted. Must replace with same number. The second fault is with leakey Horizonal Output Transsistor. This is the transistor that drives the HOT said above. Just repalce this transistor first. After replacing it, just switch ON the set for a few seconds; say 5 seconds or so, and check the heat of the replaced transitor. If it overheats within this time period, HOT is defective and should be replaced. OK.

Problem with the Sony FD Trinitron WEGA KV-27HS420
Most of the time this is caused by two ic chips on the circuit board, ic8001 and ic8002. These are components that can be replaced fairly reasonably. If you call a repairman it should cost 95-165 us dollars. However, this is just an educated guess. Good luck, Russmann.

The picture on my Sony is shaped like an hour
There is an apparatus on the back of your picture tube called a yoke.This distributes your picture on your pic tube uniformly.If this or the circuits enabling it malfunction,then you will get distortion-namely an hour glass shape.Tv has to be trouble shooted.

I was watching the news
If you include how many times the standby light flashes, that will give a fault location. Not to worry, here is a list.
Hope this helps.
Unit is dead, No blinks
- Problem in the standby power section. Might check fuse, R607,
Q601, IC601, R612 and VDR601 (should show open).
Continuous blink once a
second, no pausing - No reply from the jungle IC301 (data
bus is busy, shorted to ground, or held high), IK video path is
One blink - not
used for the self-diagnosis
blinks - B+ over current protection (OCP), unit goes to the
standby mode then displays the 2 blink fault. Could be a short in
supply of any of the circuits.
Three blinks - B+
over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Four blinks - No
vertical Deflection (V STOP), Screen goes to a single horizontal
line then the video signal muted. Check IC1509, Q1505
Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen slightly.
Six blinks - No
Horizontal (H STOP), no raster, goes to the blinking self-diagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.
- Seven blinks - High voltage shutdown. The
high voltage has exceeded 33k and the unit goes immediately into
safety shutdown. Check power supply regulation and horizontal
- Eight blinks - Problem with
the audio (AUDIO), unit goes to standby and blinks the
self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some
projection models of Sony TV sets, this code means that T8005
transformer), or the associative
components in the high voltage circuits are defective on the D
- Nine blinks - Replace D 6116 and D 6301 on
the "G" board, do not resolder as this will fix the
problem temporary. Or Panel Module Error or Thermal Error. If it is
intermittent 9 blinks, meaning sometimes the TV comes on and other
times you get flashing, then change the switching regulator on the
"G" board or check connections. Make sure the regulator is
-12 or -13 (negitive).
- Ten blinks - Check Q8014 and Q8013 for
shorts, leakage, or bad solder connections on the " D"
board. If the transistors are bad, check R8051 and IC8005, also on
the "D" board.
