Question about Sony FD Trinitron WEGA KV-36HS420 36" TV

1 Answer

Sony KV-36FS12 Lost Green

Blue and red colors work well.
Standby was flashing 4 times repeatedly. I replaced my horizontal line transformer and got my TV operating again. The standby timer light flashes 5 times repeatedly now.
It has good B/W with the color turned down so I'm pretty sure it's not CRT.
Self diagnosis service screen shows:
2: TB OCP N/A
3: TB OVP N/A
4: VSTOP 0
5:AKB 1
101: WDT 0
I've tested components on C board.(seem ok)
I've tried different cables and different video inputs.(no difference)
Diagnostic mode reset doesn't change redish picture.

I'd like to try adjusting the green color drive in the service menu.

I know how to get into the menu but how exactly do you do the adjusting once I'm in there?

TIA, TJ

Hi!

Five blinks means - 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.

Please rate this solution as FixYa if found useful.

Thanks

I have a Sony Trinitron 32 color tv KV 2168MTJ (quite old - 10 yrs old), and the standby light blinks exactly 200 times (just over 3 mins) before it turns on. Once it is on, it works perfectly. What's...


A poor solder connection on B+ is the line, Horizontal drive transformer or at the base of Horizontal Output transistor can caused that. Re-soldering these section can fix it..

Sony Wega KV-34HS510 standby blinks 7 times in red


Hi and welcome to the site,

Initially, the Sony KV-34HS510 uses the DA-4 Chassis. On this chassis, 7 blinks refers to the fault "Horizontal Deflection Stopped" indicating a problem with the horizontal section. Offhand, check, replace the HOut transistor and have the FBT (flyback transformer) ring tested.

Good luck and thank you for asking.

6 horizontal lines


I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

Sony blinking standby light


This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short. You need to take it to a techincian and have it checked out. It would be wise to get an estimate! Stargazer
