Question about Sony FD Trinitron WEGA KV-34HS420 34" TV

1 Answer

Sony Wega #KV-36HS420 has been slow to come on for months, but now will not come on at all. Owner reports "7clicks" as frequently happening during the duration of the "reluctant come on" trouble. What are the most common 3 or 4 parts that I should suspect? Many thanks for all past help, especially for Kapishtech's MOST COMPREHENSIVE help on a fridge-freezer yesterday. All the best, Frank // Gramps // renthelp // BDCD928E

    Super

    I got my hands full with this one, but I betcha I'll win. I've been winning big time with Welcomegee and Taran2005 and the gang making me look good.

    Glad you can make a living without having to go too far away from your #1 squeeze. Me too, but so far she's saying that she won't sign up on paper for another 55 years; sez I'm just like all of her other bad habits: "One day at a time." Maybe Fixya can help on this?

    Thanks again for grrrrreat faaaaaaast service. I'm going out on this Wega in minutes.

    All the best,

Hi,
If this tv fails to turn On then its standby/power light will start flashing in specific order like 4 times then 3 seconds long pause, again flashes 4 times etc. This is an error code that shows particular defective section of tv.
Let me know how many times its flashing to determine problem section in tv.
Thanks.

    Hi Welcomegee --

    Always good to hear you, but if I were your age today I'd be at the beach with a sweet young thing -- maybe even my own sweet young thing.

    Customer remembers mostly 7 blinks, then a pause and 7 blinks, and so on. They also remember 6 blinks occasionally, and [only sometimes] 5. Husband thinks that they heard clicks along with the blinks.

    Hope this helps. Thanks for speed.

    Haha, I do not have any beach in area but sweet thing is with me.

    error codes 5, 6 and 7 show different sections for problems.

    5 rimes blink = White balance failure, related to picture tube performance, possible causes are IC90001, IC9002, IC9003 faulty on CH boards. CRT drive IC2801 is faulty or Screen volts are set incorrectly.

    6 times blink = LOW +B Over Current Problem /Over Voltage Problem, possible causes are +5 line is overloaded. (AY, BY, MY Boards). +5 line is shorted. (AY, BY, MY Boards). IC504 is faulty. (AY Board)

    7 times blink = Horizontal Deflection Stopped. This is bit complicated problem and deflection board is involved. Need to have schematics in hands to test various voltages on many parts to narrow down problem area.

Kv-36hs420 shuts off on its own


Most of these have a error buffer---if set shuts down power light will blink in a specific sequence---it will only point to the general area of the problem and frankly most of these are not being repaired as the weigh a ton and repairs usually result in the set being replaced with something less expensive and with new features.

I have fixed this problem, on one of these.

It is a voltage regulator, and it probably died after a power outtage or surge,
am I right?

Get it to a fixer guy, Its a very affordable repair.

We have 7 blinks on my KV-36HS420 Sony Wega Triniton. It will come on with only 5 seconds of audio and then shuts itself off with 7 blinks. What part does it sound like needs to be replaces


The power supply in all likelihood. Not something you can do. Any tv repair can take care of it but will likely charge $25-30 for an estimate. They have to spend a bit of their time to check it out. The cost of the estimate will go towards any repairs.

SONY WEGA KV-36HS420 will not come on


The blinking is an indication that the set detected a problem. The code usually indicates a bad regulator circuit. If yu can solder, you can probably fix this your self. Please let me know if you wish to attempt the repair. If not, expect a parts cost in the $25-$40 range plus the local labor rate for the repair.
