KD-36XS955 Sony Wega Trinitron 36" 4:3 HDTV Problems

I have a Sony Wega Trinitron CRT 36" HDTV(KD-36XS955). I bought this 4-5 years back and all has been fine. I have noticed recently that the screen looks like it's bowing down on the sides. It's especially visible when viewing something in widescreen format as you can see the black bars clearly bend downward on both sides. There are also 3 horizontal black lines that i think might be dead pixels? these lines are barely noticeable, but once you see them, they get annoying. any help would be appreciated.

Thanks,
Andrew

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.

Hi,
7 times red light blink error code indicates Horizontal Deflection stop problem.
There are two ICs on DZ Board, IC6501 and IC8002, both ICs are same number that is MCZ3001D, replace both ICs to solve tv problem.
If you are handy with electronics stuff repair and can replace/ solder parts in circuit board then can attempt above solution OR call local vt repairman to do this job.
Let me know if you have additional question.
Thanks.

It is one of two issues, the blue video driver is defective, or the blue gun in the picture tube is open. This will need a tv tech to varify the problem and suggest a course of action.

Sony kd-36xs955 Turn tv on all channels fuzzy,once warmed up,everything is good.Now when you try to use the hdmi port for PS3 nothing there.The tv has had problems before like it would shut off and blink...


Count how many times the standby light blinks at one time. These blinking are fault indication. You can get an idea about the faulty circuit part inside, from these number of blinks. After make it sure, if you wish to get more details about Blinking Codes to Sony TV sets, check this link.
