Sony Trinitron	Can't Post

My TV sony Trinitron 2003 model # KV32FS210.
the problem is when the tv turned off wont come back on some time takes hours some times takes days to come back on, now I leave it on all the time but if there is a power outage or the power flshes off and on it wont come back on.
there is a small red light flashes on and off at all the time next to the switch on off botton and it says sand by/timer above it.
please help, thank you

meamer2;.....

Does the TV still have sound when the problem acts up ????
Just curious.... Wink

...

Try this anyway;....

Sony has a self diagnosis code for their big screen TVs that may also apply here...

Quote

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.<<<

The "><" part is what I'd like you to try...(Don't worry about the rest..)....

The "screen" control" is on the flyback...
Remove the back cover from the TV...
On the chassis is a transformer that has a heavy red wire coming from the top & connects to the side or top of the CRT...
That wire has ~30,000 volts on it when the set is on & can hold that charge for quite awhile even when the set is off & UNPLUGGED....
So keep clear of that wire...
That transformer is called the "flyback"...
On the side of it there are 2 controls...
One is called "focus" & may be marked "F" or "focus"...
The other one may be marked as "screen" or "G" or "G2"...
Mark the side of the control (G) in such a fashion that you have a starting point marked...
With the set on , (Give it about a minute to warm up) turn the "G" control SLOWLY clockwise till a pix pops in....
As SOON as it does STOP turning the control...

Hopefully , that's all it needed...
IF you are successful , this means the CRT has aged & could be on it's way out...
You have an 8 year old Sony & that's about the norm for them...
Have no fear , tho , this adjustment could give you some more years of use...

I really hope this helped...

GOOD LUCK.... Sly

meamer2;....

Somewhere along the line I got the impression that the set came on....
The adjustment I posted above will not work unless the set comes ON & STAYS ON......
So to refresh my memory & clear my head , the set gave 5 flashes & is now DEAD ????
You hear no clicks or HV coming up ???
Correct ???
Does the set STILL flash 5 times ???

BTW;...
Reset the screen control back to where it was when you started...

Seems like your problem went/is going from bad to worse.... Unsure

....
With the back cover off , turn the TV on & look into the rear of the CRT neck & see if you see a small orange glow inside...
Also , leave the TV on , put your forearm close to the front of the CRT about an inch or so (Where you watch the pix) & see if you feel a tingleing of the hairs on your forearm...
PLEASE post results....THANKS.... Sly

This may sound stupid but; try blowing in the right side of the set with a blow dryer on high heat for several minutes and try powering on again. Wink

Not really , BUT , you ARE confusing the issue here....
If it's OK with you , let's follow ONE train of thought...
We don't need to send this guy running around doing several things at one time...

meamer2;....

OK , here we go.....

How much electronic/TV repair background experience do you have ????
Do you have a DVM & know how to use it ???
Do you have soldering experience , a decent soldering iron , desoldering braid , solder ???
Can you take & post pix IF needed ???

I think your "present" problem is that you do not have any HV coming up....
This is "usually" caused by bad solder connections...
Or possibly bad parts in the Horiz circuits...

PLEASE answer ALL questions & post....THANKS.... Sly
