20 Most Recent Sony FD Trinitron WEGA KV-36HS500 36" TV - Page 3 Questions & Answers

Could be a fault in the powersupplym could be a flyback issue it will need to be evauluated to see what is the cause now most shops will tell you what it is without charge that way you can decide to repair it or replace it I am telling you it could be a power supply issue or flyback I will need to look to rule it out but at least you know what the problem could be and determine the cost of repair. please do click the end session to your right, Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

if u r the macanic of TV then check the entire power supply n standby circuit

no, inside is o technical problem,

need repair,

try making resolders on power supply ckts, try also adjust screen voltage,, check crt socket,,if all of this dont solve it, try to rejuvinate the crt.

No,no way. It is just coincidence. NOTHING done on any remote can cause any component damage.

I would try replacing the ic on the power supply location is ic8002 that will generally fix this issue part# is 6-705-810-01

Only if the menu screen has the function settings for screen sizes. Other than that you get what you get or hook up TV with only the coax cable.

Either contact Sony to see if they will do anything for you or repair it or buy new TV. Here in Canada the repair is approx. $1K

You may have had a slight voltage spike either just before losing power (posible lightning strike?) or after power was restored. May be as simple as a blown fuse. If you can check yourself it should be located in the incoming power line; if you can take it to a repair shop most can find and fix cheaper than a new TV but will charge a diagnosis fee of about $50.00 to $75.00.

The 7 blinks in sony tvs(sony errors codes) usually indicates a high voltage shutdown(tv has exceeded 33k volts) . The power supply regulation and/or the horizontal circuits may be at fault.Unless you have a good knowledge of tv circuitry you might need the help from a local tv repairman. Hope this help. Good luck
Please do not rate this answer(unless it helps) as it is only a suggestion.

unplug the main power cord of tv from wall outlet for three minutes then reconnect it and check.if it still shows same blinking check out how many times the light blink.the error depends on how many times light blink. also check if la,mp light is blinking that ,means lamp needs replacement. ------ as follows:-- if the red light gives Seven blinks - its high voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. there are some common breakdowns in the High Voltage circuits in this set. One is the FLY BACK TRANSFORMER . Another is a small high voltage capacitor in the sweep corrction circuit. If you have no solid state repair experience with tv sets , play it safe and call in a tech to assist you in this repair. ----- if the red light blinks 6 times then The 6 blinks indicates a poblem with the 5Volt line on the A,B or M boards. Also there could be a problem with IC504. This is most likely not a repair that should be attempted by an untrained homeowner. ------ you can get the requiredboard and components at ----- www.partstore.com -------- or from ------www.radioshack.com ----

the cost for repairing parts is not more then $30.its not a costly problem but a technical problem.
if you are not familiarwith doing this you can get it done by local tv repair technician familiar withthis model tv.
This will help. Thanks please keepupdated.please do rate the solution positively .thank you for using fixya.

it is problem in power supply.may be some of components are demage such as capacitor or diod and mosfac .Repear it by a good technician in your area.

Is the flashing get more rapid as the set warms up and even once its on is the picture somewhat out of focus around the corners? If the answer is yes then your picture tube is showing signs of age. The older they get the lower the emissions are. The replacement picture tube part number 8-735-048-15 is showing a cost of 741.45 from the following web site. Please take a few moments to rate my answer. Thanks...

common problem. sony makes a power suplly service kit that will repair it. cheap. the power supply is very efficient but ver sinsitive to power surges. easy ans cheap. good picture is worth fixing.

download my KV-32HS500 it may help with your problem contact me at [email protected]

Ur high voltage is dead,the FBT,the flyback transformer is dead,the big block of plastic with a red wire with a cap hook to a CRT(tv tube).

Hi


The blink codes only point to the area that the electronic tech should start checking. It does not indicate which part to replace. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone who has electrical expertise and knows how to solder/re-solder components. You did not mention how many blinks are there but still the common problem in these sets are the light blinking 6 times which indicates there is a problem in the horizontal circuit. Likely a failed horizontal output transistor which needs to be replaced.

However if there is seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. This can be the high voltage splitter.

Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC5004, Q1505.

If you decide to repair this set yourself you will need to be careful, this set feeds the tubes with tens of thousands of volts and if you are not careful and do not know exactly what you are doing you can be hurt. There are also many different caps in the set that hold a charge and can hurt you as well. In addition I have seen many good people destroy their sets because they did not know what they were doing and either broke a circuit board or damaged some traces causing their sets to never work again.


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


Thanks

These sets are really expensive to work on. Most likely you have a bad "D" board. I have never had much success repairing these down to component level. Have a repair shop check it out. These are expensive tv's and well worth a check out charge.
