SOURCE: Sony FD Trinitron WEGA KV-36HS500 blinking red light 6 times

My Sony KV36HS500 Trinitron is doing the same thing. Last night the next street over was hit by lightning. The "7" blink pattern was happening, so like the manual stated, unplug it for 4 hours. Which I did. The t.v. is back up and running fine. It's a nice t.v., better than the plasma I paid over a grand for, that's already shot. It's a good t.v. and good that Sony put in the stand by protection to prevent the t.v. from dying an unnecessary young death. Patience, don't rush it, unplug the t.v. and leave it sit. Also, don't use a power strip, that was my mistake, and unplug your t.v. if storms are in the area, I was too lazy to and now I had to deal with this, in 8 years, only twice did this happen. I'd buy another one tomorrow if they still made them.

The relay is in the power supply area. I am sure that the fault is not the relay.

It is very common that there are various components starting to go off spec from age. Most of the failures are in the scan amplifiers and power supply areas.

It is also possible that the CRT emission is too low from age. What happens is that it is on the minimum edge and this explains why the set may turn on some of the time.

When the main uPC in the set sees any potential fault conditions it will go in to a protection mode to prevent damage and to be safe. Your set is probably borderline to operate.

Considering the age of your set, I would be shopping for a new TV set.

SOURCE: Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

Sonywega takes. 30 try's to come on


The SMPS control cirlcuit [power supply regulator inside]; does not get the start voltage. This is a common fault to Sony TVs and related to some resistors at that circuit stage. Even though the cost of component is very less, locating the exact faulty one is a skilled work. Contact any service technician. If you wish to get some details; check the site linked here.

It takes a very long time for the tv to come on, the light blinks a long time before a picture or sound comes thru. What is the problem? How can I fix ?


I m not sure how long you are talking about, but I have a Sony 32" Wega trinitron and I have experianced the same thing for some time now, It has always took a while to start up. After start up the color is slightly weak for 30 seconds or so before the tv gets good and warmed up. I don't think you have a problem, just the way these tv's act. Some have the quick on feature and they have the current flowing thru soeme of the modules in the set to keep them ready to go when you hit the on button, I suspect theses tv's do not have that feature.
I hope This helped you somewhat.

Sony wega 27 inch


I posted originally about a year and a half ago about this very same problem. It is a known defect with the WEGAs that Sony refuses to do anything about. Here's the thread with my experience - the upshot is, try doing a "hard reboot" by unplugging it and leaving it unplugged overnight. That worked for me for about 18 months, but no longer...I'm replacing my 5 year old WEGA today (NOT with a Sony).

36 inch sony wega trinitron


I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.
