I have a Sony trusuround a older model an the red button blinked on an off


Mine did this last year. Drove me bonkers! Acted like it wanted to power up and then just went off again. For me, it was a bulb replacement. Not sure your model number, on the back, but most can be found on amazon. http://www.amazon.com/KDF-42WE655-KDF-50WE655-KDF-60XBR950-KDF-70XBR950-KDF-60X8R950/dp/B003ISY34U/ref=sr_1_2?ie=UTF8&qid=1386773019&sr=8-2&keywords=sony+replacement+bulb&tag=donations09-20

TV has been working great for the past 6 years, this morning when turning on the TV nothing happens except the standby light flashes about 9 times on and off. No click like I usually hear when turning on...


Hi Dave,

We have had this same problem twice now - the first time under warranty (no problem) and now currently. The 9-blink error code refers to needing to replace two diodes on the G board. Specifically, D6301 and D6116.

The warranty time, the repair guy came and resoldered the new diodes onto the G Board, reinstalled the board, and was on his way. We had no problems for the next 3 years.

THIS time I ordered the two diodes from Andrews Electronics (www.andrewselectronics.com) am removing the G board myself and taking JUST THE BOARD to a local TV repair guy. This is a LOT cheaper than calling Sears or taking the whole TV to the repair guy. Here are the links to the specific diodes:

D6301 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/6-500-567-21.aspx

D6116 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/8-719-081-97.aspx

They are a heck of a lot less expensive than other places and the customer service I received was great!

I hope this helps!!

Convergence problem


If the convergence is out on that set you most likely do not need to make an adjustment the circuit will need to be repaired. There is a stk on the convergence amp board that needs to be replaced. A good tv shop will run you somewhere between $300-$500 to do the repair

Dave,
Without a doubt it's worth the repair. The convergence amps have most likely failed and taken with them the +/- 30v line. Your unit takes two STK392-040 Sanyo built Ics at board location Icz103 and Icz104 and usually one or more pico fuses and some low ohm resistors. F1018 sometimes opens due to stress but generally it's just the two 6.3 amp pico fuses and if they have opened I strongly recommend replacing them with a 6.3 amp slo-blo pico.
The low ohm resistors at RZ147, RZ146 usually show signs of heat stress and may even be burned beyond recognition. Testing at that point is almost unnecessary but will confirm their change in value. Almost always they need to be replaced.
A quality shop will have this unit back on its feet in no time - faster if they have the parts in-stock, which you might ask about when you shop around for a good repair facility.
Have a great day!
Bill

Fuse Locations


If E907 is open it's merely a symptom and NOT the cause. That said, there are several pico fuses in that unit. The three main are E903, E904 and E907 Hitachi p/n#AZ00106M If any or all of these are open it is an indication of a problem associated with the deflection board. Hitachi uses tiny yellow pico fuses. Most common are yellow and green. The "E907" is going to be printed right on the board next to the component it identifies. This is known as a location number. But let's get onto solving your problem... The fuse is not going to be the resolution. Having the deflection board repaired will. The regulator IC902 (remember that's a location number) is an STRF6628 it together with the horizontal output transistor and other components need to be tested to find out which culprit opened your pico(s). For this you'll need at a minimum a DMM meter, and ESR meter and a 20mHz scope. If you're lacking any of these you stand about as much chance of doing this repair as you do winning the lotto - - three times in a row... But, you could pull the board and send it in to PTS Electronics who rebuilds boards for a flat fee... problem there is it will be torn down and waiting a week or two and if you have no memory for all those wires, and where they go when you get the board back,,,, well I wouldn't give that idea much hope.. Lastly, the alternative, is calling a reputable shop and have them estimate the repair. If you can take it into them you''ll cut the cost significantly. And if you're not sure where to find a reputable shop contact NESDA and have them give you a referral to one of their member shops in your area.. Hope some of this helps.. Good Luck Bill
