Question about Sony FD Trinitron WEGA KV-32HS500 32" TV

1 Answer

Sony kv-32hs500 Three days ago the tv just shut off and the standby light started flashing a 7 flash sequence. The tv would not turn on the rest of the night. Next morning the tv turned on again but after turning it off it would not turn on the rest of the day. This morning it turned on again and I was going to just leave it on all day but my wife shut it off on me. It will not turn back on. We do get a 6 flash sequence as well at times. I will try again in the morning.

    When I turn on my tv and the light start to blink 5 times or when I hear the static sound, the tv should turn on. But when I didn't hear the static sound when I started to turn on the tv, that means the tv won't come on after 5 or 7 blinks. It all started when I keep on pressing the power button on my remote and then it happend.

    I'm having the same problem with my Sony FD Trinitron KV-32HS500. It started about three weeks ago. I wasn't able to turn on the TV with the remote or the power button on front of TV. No sound or picture, just 7 blinks (sometimes 6) of the standby light, pause then 7 blinks again, etc... . After a day the TV would turn on again. Then it wouldn't come on for a couple of days, but would then work for a couple days. I'm now on the TV doesn't turn on cycle and it's been 3 days. Please help.

Most probably the IC504 (Sharp PQ05RD21) on A-Board went bad. This model TV, including mine, is notorious for having this problem. The IC is rather easy to find and inexpensive (around $2.50). Your main problem will be desoldering the old one and soldering the new one.

Good Luck.

Im having a problem with my TV turning off and the standby button flashing 7 times, after it shut off. What can I do.


hi,
Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.
ok

KV-32HS500 WON'T TURN ON standby light flashes 7 and sometimes 6 times and has flashed 4 times also.


These are sony error codes while in protection mode. The 7 blinks means high voltage exceeded 33k volts ,caused by either horizontal or power supply circuits.
The 6 blinks code is for no horizontal deflection, and the 4 blinks code is for no vertical deflection.
So the one thing they all have in common is the power supply that will need to be repaired before you can use the set again.
Hope this help. Good luck

TV wont turn on, sandby light flashes 7 times.


Any malfunction associated with a flashing stand-by light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Sony kv-30xbr910 my tv won't turn on and the standby fashes 7 times


Good day.
Your unit has issues with the high voltage section. Particularly the vertical and horizontal sections. Blinking lights indicates that your flyback is not osscilating to distribute the supply to the sections. Please have it checked by a repaiman.
