    I expected to get some more troubleshooting tips for example I think the blinks has an interpretation, I do not have the data to interpret the blinks that is the reason why I am reaching out to the experts.

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. X, Y sustain, buffer boards controls picture, fires the gas, and many others functions. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged/leaky capacitors on these boards and replace whichever has gone bad. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

    The 7 blink code on this model would not
    indicate a power supply, as you have already found out. There are 3 possible
    boards that are causing your failure the SC, SU, and SD. The most common
    failure is the SC board but it's easy to check if it is one of the others which
    are causing your problem. In some cases all three need to be changed.
    As
    you have the service manual check all three and replace whichever has gone bad
    or replace all three.
    Please do accept the solution if the issue is resolved or else revert for further assistance.


    Thanks

    As I said you have to change all the three board completely.

Y-sustain drive should be checked. These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can vet an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts.

I just tried to turn my sony 32" trinitron and it


Hello
I thinks that you have a concept of soldering and have the knowledge in following the printed circuit board tracks.
Seven blinks in Sony sets denotes a high voltage shutdown. When the high voltage at the final anode of the picture tube exceeds 33KVDC, the unit goes to shut down, and the system control Ic detects it and gives you this seven blinks as indication. Mainly this fault must be due to increase in the main DC supply line on the circuit board. Usually Sony 32" sets are working at 135VDC, as supply voltage to its LOT [Line Output Tranformer]. You first do one thing. Isolate the supply to LOT by making a break in the print very close to LOT so that we can resolder it later. Load a 100W bulb in seris with the supply point and negative rail in the circuit, and switch on the TV. The bulb will glow, and measure the voltage across it. It should be around or lower than the above said voltage. If it is more than normal, check the main power regulator section. Normally Sony sets have STR regulated power supply system. If any of its solder joints goes loose contacted, this fault [over voltage] may occur. Check for all solder joints for any loose contact. Loose contact in printed circuit boards are very difficult to locate. We in service field, resolder all the suspected point bt applying a little more solder. In most cases this may be the reson for seven blinks. If it does not helps, change the STR with same type and number. STRs are very accurate constant voltage regulators, and will be no adjustement presets there to adjust.
After resoldering the suspected points, switch on the set again and measure the voltage across the bulb. If you see it is normal as said above, reconnect the breaked point.
Before doing all of the above, first adjust the screen control of the TV to a lower value by rotating the screen control to counterclockwise, and see whether the screen comes and stay steady or not. If Screen Control Potmeter is defective, this fault may occur.
These are the main reasons for seven blinks on Sony TVs. Ok.
Wish you sucess.

TV won't turn on, standby light blinks seven times over and over


Hello
Seven continous blinks denotes that your Sony TV has some high voltage more than normal inside its final anode of your TVs picture tube.. When high tension volltage exceeds abve 33KV [33,000VDC], to the final anode of the picture tube, TVs microcomputer Ic will detect it and get it shutdown, to prevent it from further damages.

You have to check its power regulator section for this fault. Usually Sony TVs uses STR regulated power supply regulation in their TVs.
You must open the back cover of your TV, and locate the power regulator section, sometimes be as in a seperate board or in the main board itsef. Check for any loose solderings it it. As components in the power regulator system will heat up during working. As it heats up and cools down for several times, some loose soldering may occure in it, and is usual. It is difficult to locate the exact point of loose, and is risky too, as the power supply regulation side is directly connected to mains supply and will always be "Hot", so i recomends you to resolder all the points, especially the points of high watt resistors in it. Resolder the the STR legs also. Sometimes the STR itself may need replacement. If so go for the same number and type. This might retify your problem.
Normally Sony 32" TV has a working voltage between 125 to 140vDV, at the secondary side of the power regulator. It it exceeds this type of problem will occur.
Take all precautions we take when work with an electrical equiments. Keep chlidren away from you, and note even stand beside you when you do works. Keep an adult beside you as a precatiounary measure. As high as 27KVDC [27,000VDC] points are there inside your tv, while it works. Take care. Never use metal a metal chair. Ok

My 42in LCD is 3 years old and when I turn it on it takes about 5 times of this to get the picture to come on and sometims the tv blinks and shuts off what could this be


are you saying turning off and on?..un-plug the tv,pulling the board out a little....get a magnafying glass and inspect all your solder joints,for cold or bad joints.How many times does it blink before it shuts down? resolder all bad joints.....its a start from what you are telling me..let me know futher.hope this helps.........

Blinking red light, no picture


When a tv shuts itself and gives only the blinking red light/led, it means that there is a hardware problem on the tv. Most tv's now has the auto shut off feature to protect itself from further damage the moment it detected a hardware problem.

You need to check the inside of the tv for the following that needs replacement:

1. blown fuse
2. bulging or leaking capacitors (you should never touch these for safety measures)
3. loose parts that needs resoldering

If you are not technically skilled to do electrical jobs, you should have it serviced by an authorized tv technician.

Sony TV shuts off automatically


1.Check first if the shutdown of your tv follows a certain period of time. Example after using it within 12 hours it automatically shut down. If so the the matter is only on settings of your tv.
2.But if your tv shut down at an irregular time the problem is in your board. In this case if your tv still work but still shutting down automatically its better not to use it so that their will be broader damage.
3.The most common defect on this case is loss contact of components due heat and mechanical undergone during the usage of the tv. If you know how to resolder board, try to resolder the components specially those who are showing loss contact. You can recognize it because a good solder one has shinny and no round like on the soldered surface.Try also to resolder important parts such as IC's and transistors. note : a good resolder needs to be done in order to avoid problems and damage.
4.Another possible cause is the tack switch for channels,menu,power and etc. You can remedy it by spraying it a contact cleaner.
5.If the problem still going even after the procedure its better to bring it on reliable and trusted service center.

Kv 32hs420 7 slow blinks form the led light sounds comes on but no picture shuts it self down then give me 7 fast blinks hhhhhheeeeelllppppp


The slow blinks are normal at startup. The quick seven blinks indicate that a problem was detected and the set is shutdown to prevent further damage. I'll look up your model later today and post the probable defective parts. Are you planning on attempting the repair yourself?

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
