you may have cracked the circuit board when moving , sounds like a bad vertical circuit. look for bad connections around vertical ic or flyback transformer

The power supply board is failing. There are twi integrated circuits in the horizontal drive circuitry that have to be replaced. The original integrated circuits are the same type and you will see written on each..."MCZ3001D" and need to be replaced with Sony # 670581001 or the "D" board with those parts on it needs to be replaced. The cost of the entire board is high-about $375.

I
have over 10 years experience in electronic tech
support.
I
know this isn't what you want to hear, but the problem you've
described can't be fixed with troubleshooting.
Your TV
will have to be repaired. There is a part that has developed a defect
and needs to be replaced. If you're still in warranty, the TV will be
repaired at no charge to you. The warranty would likely be at least
one year from the date of purchase from the manufacturer. If you
purchased an extended service
plan
they will repair the TV at no charge as well.
If the TV is no
longer in warranty, it will likely cost a minimum of $150 parts and
labor. This is assuming that you only need one circuit
board
or small part. If the problem is more than one of the circuit boards,
the price of repair could go much higher.
I hope I've provided
you useful assistance and that this information allows you to make an
informed decision as to how to proceed from here. Please be sure to
vote on my response. I hope I've earned a good rating from you
today.
Please let me know if I can be of further assistance.

ONE: Unplug it for at least 4 hours. That is what we call a hard reset.
TWO: If the hard reset does not help, then it will need further diagnostics.
The following bulletin may be of help in your learning about what is
going on. Please refer to it below. Then let me know if you need
further assistance.
Have a great day,

Sony Blinking Codes
Many of the later model Sony TV's have a built in Self- Diagnosis function. If
the timer/standby indicator is blinking, this could be an indication of the
problem with the unit. The diagnostic blinking will occur automatically with no
action required by you to engage it.
The timing of the blinking you see would be as follows: two to eight blinks
(depending on the fault) about a third of a second apart, then pauses for 3
seconds, then the two to eight blinks about a third of a second apart again.
Here is a list of the problems that might have occurred indicated by the
number of blinks. The words in parentheses are those which you will see for
each of these faults on a diagnosis screen described later in this article.
Unit is dead and there are 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 As Discussed Above---
No reply from the jungle IC301 (data bus is busy, shorted to ground or held
high), IK video path is defective.
ONE Blink--- not used for the self-diagnosis
TWO Blinks---B+ over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power 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 Vert. Deflection (V STOP), Screen goes to a single
horizontal line then the video signal muted. Check IC1509, Q1505
FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,
try turning up screen slightly.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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 circuits.
EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and
blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.
Intermittent problems ?? This is a great feature. You can also bring up
these fault codes ON-SCREEN to see a list of the problem numbers with the
abbreviation of the problem and the number of times this problem has
occurred. This is slightly different than entering the service mode. To see the
diagnostic screen, Press the following buttons:
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
codes.
So, now that you know about these self-diagnostics, how do you use them?
Say that you have a set with a black screen. You see that the LED is blinking
4 times....This would tell you that you have no vertical and that is why the
video is muted. If it was blinking 6 times, you would know that you have a
horizontal fault.
It's not a sure cure, but it's a little better than a poke in the eye with a sharp
stick.
IMPORTANT: after you repair the unit, PLEASE clear the values on this
diagnostic screen. These codes do not reset themselves after the fault is
corrected, so if you don't clear them, you'll be seeing "old" fault codes the
next time you enter this screen.
Clearing is done by going into the service mode ( display, channel, 5,
volume plus, then power ) then press 8 and Enter, which of course returns
everything to the factory preset condition.
