Possuo uma tv kp51ws510 posso usar o stk392150


no - stk392-560 can only be replaced by the same or a stk392-570
when buying replacements make sure they are not the junk generics...anything under 20.00 each are generics....the real sanyo versions are 20-40 each on average but worth it since they will last

Hi,
3 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.
Click Part Store to see an image of required chip and price info.
Local tv tech is recommended if you have no experience of working in tv circuit boards.
Thanks.

Picture distorted, bowed in with shadows on text. Cannot adjust convergence using direction on menu guide.


This is a very common problem with all projection tv's2.gif it is the stk392 ic's in your set have failed. You can attempt the repair yourself as long as you understand the risks involved when working inside a tv, otherwise you can get it repaired by a pro and i would guesstimate it will cost somwhere between 250 to 300 to fix. the ic's are located on a big heatsink and the number stk392-xxx xxx If xxx is beteween the numbers 110 and 180 you can use the stk392-180 for the repair, and i would recomment doing this. if it is stk392-560 or another number replace only with the same ic.

My sony projection tv has bouble image. can i


Well repair of TV depends on your own skills and if you have any experience of electronics stuff repair then it would not be difficult. This kind of repair requires good parts soldering in PCB expertise.

Your Sony KP-51HW40 seems have problem with convergence out ICs (two ICs) that would be replaced. Both ICs STK392-560 are located on D Board and available in Part Store.
Thanks.

Be aware:-
There is electric shock risk involve in TV repair.
You should have strong electronics repair knowledge / experience and good soldering skills. Repair your TV at your own risk.

Mostly 3 blinks in this model shows convergence out ICs failure and you need to replace STK 392-110

Its big black IC and TV has 2 mounted on silver heat sink at main board.

HERE is a pictorial web link and you will see how you can replace these ICs.

STK392-110 are available in Part Store.

Good luck.

Sudden shutdown - Red light blinking 3 times


Replace both convergence Ic's Stk392-110 and personally I'd use STK392-150's for greater reliability. Also check all 2.2 ohm 2w resistors for open or change in value and replace as many as needed...

Does it blink three times if so its a convergence problem -your set uses stk392-110 i usually replace with stk392-150 or stk392-180 these are more stable. if you have no soldering experience or electronic experience. but if you want the challenge go for it. remember that there can be several thousand volts in this set even when unplugged.

It sound's like I am having a over surge problem


Don't have a repair come to you take the TV to them... And no, it's not something you can repair yourself. The symptoms you're describing are a common problem with the PT51HX41 in that one of the convergence amps has failed and most likely opened or dramatically changed one of the feed resistors in that circuit. Your amps are IC7001 and IC7002 both STK392-110 and I personally recommend using an STK392-150's for greater reliability. The feed resistors in that circuit are a 2.2ohm/2w and most likely you'll find one or more heat stressed... When researching for a shop ask them if they have the STK392-150's on-hand and if they have any problem subbing to that for greater reliability. Most shops will have no problem. Sorry if this wasn't what you wanted to hear - please don't kill the messenger. As a certified tech I most hate having to tell people bad news in a solution. Good Luck Bill

Blue Convergence


Convergence problems are generally simple repairs, presuming you know how to solder and have a bit of brains about you. Eventually every projection set will have this problem - STKs are usually at fault (STK392-010/020/040, STK392-110/120/150/180, etc) and are easily aquired and replaced. Sometimes a fusible resistor is taken out in power supply circuit, sometimes a resistor will burn. Generally easy fix. Repalce STK and any fusible/blown resistor - you will need a multimeter, decent soldering equipment (NOT a 40watt iron or gun from Radio Shack, unless you're brave) and the replacement parts. But as everyone says - servicing TVs can be hazardous. Call a servicer if you're concerned, but in-shop repair should cost less than $250 - it would never exceed that at our location.
