Sony TV Diagnostics

Evening all, i hope you can help. I have just set up my brand new Sony KDL-46X3000. However, upon turning it on for the first time it has gone straight into diagnostic mode. The standby light is flashing with 2 blinks. Is it something I can fix or will I have to take it back?

The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.

Keep us posted.

I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.

Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???

Yes....this blinking code is a diagnostic fault code which is a good thing, you count the number of blinks and it tells you where the problem also can see it by pressing the buttons, DISPLAY,CHANNEL,5,volume - not + ,then power....In your case it blinks 5 times,its in the video out,you need a desoldering iron,solder,rosin core 60%tin and 40%lead...remove and replace these,Q761,Q705,Q732 on the C board also Q218,Q219,Q220 on the A board.hope this helps.......

Sony tv wont start up???

It seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other). Do you hear any clicking sounds?

Or else it could be that the CRT tube is faulty and will need to be repaired/replaced.

Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,

It may be worth getting fixed up. If you decide to do so, call around, as shops have different rates and different expertise.

Hope that helps!

Sony TV not turning on

Chances are the Power Supply failed because the Horizontal circuit failed. It would not be out of line if the repair cost ran 250.00 plus.
It is probably not worth fixing due to the age of the set.
Hope this helps,

Sony Trinitron TV. No picture; red standby/timer light flashes.

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

If the screen won't come on then the diagnostic will never show. The 4 blinks is an error code. If the set is older than 12 years then it doesn't owe you anything, you got your money's worth out of it. Average life of any tv from that genre is 8-12 years. It's time for a new set, or take it in for an expensive repair ( pending parts availability).

Trinitron KV-36FS13

The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.

Dropped TV!!!

Worth fixing? Sorry, probably not. My experience with problems like this are such that the set will keep being repaired as new issues develop. The click and shutdown are a safety feature and are kicking in for a reason. Take what you'd spend on repairs and get a new TV. It will be cheaper in the long run. You might make some $ back by selling the set for parts. Who knows? Hope this helps.
