Hello everyone, I need the plan of this TV No. of chassis YH-200-02 because the horizonal transistor was burned and this one has a D2499 and the R414 resistor is burned and the colors cannot be seen if someone helps me please I would appreciate it from Thank you all very much ...

Hello ... there is change the horizontal Q401 d2499 and change the electrolytic capacitor of 160v x 1uf and I put another value of 160v x 33uf and I go but with a vertical line and I do not know what to do if someone could guide me from many thanks

from the bottom up the line or from side to side of the screen?

Bottom up

the horizontal yoke does not open, check the tuning capacitors and the yoke connections to the circuit

Ok ... I measured the integrated chroma leg 28 to ground that says H vcc (says 9v) medi and there are 8v

That is not a jungle or chroma problem as you say, since the horizontal exit is working. The problem is in the yoke circuit, it does not open, it has no horizontal width. that burned, the change is in parallel with a diode.

Exactly ... that resistance is left by Mr. I do not have another one from another chassis and today is a carnival holiday I will have to wait until tomorrow to buy one leave it because in the measure of measuring 15k it measures me 18.08k I do not know if that will be the problem the ones that I have spare are 1 ohm of 1/2 watt

good morning leonardo good day victor e measured his yoke how much hom measures would be the one who opens the width

that resistance must be connected because it is in parallel with the diode and goes to one of the legs of the yoke. Your problem may be there

Responder

The yoke measured it and measured me 4 ohms and well I'll see if I get a resistance of at least 15k

I DON'T UNDERSTAND BECAUSE VICTOR HAS GIVEN THE CIRCUIT CORRESPONDING TO HER PLATE AND YOU REQUESTED THE VALUE OF A RESISTANCE BUT IT CORRESPONDS TO YOUR TV THE CIRCUIT THAT HAPPENED THE VICTOR COLLEGE AND IF THAT IS SO, PLACE THE CORRECT RESISTANCE

you read the post, input the map of the TV, that is, the diagram already wants to know the value of the r414

Responder

Ok, I'm going to try it ... there is no risk of burning something if I put a 1.8k 1/2 watt?

Responder

VICTOR E TOLD HIM 1-8K THAT IT WOULD BE 1,800 HOM PUT SERIAL RESISTANCE UNTIL YOU GET THAT VALUE AND READY

I would recommend that you change the diode that is in parallel with that resistance, and if it is possible that it is 1 watt or more

Forget the integrated jungle, that is working, the problem is in the horizontal output. Change the capacitors in the yoke line and the horizontal transistor.

hello leonardo i have a circuit i say it takes micro i701 dmc42c2008 n chroma i501 the 7688 source carries i 801 str 5707 horiz q402 d2499 r 414 15k 2w notice if it matches the data with your tv or describe the ungrateful ones that your tv brings if I have the circuit Cheers

It is not that apology ... this one takes micro..JYE-200M93 ..... CHROME THIS CARRIES TB1238BN AND STR S6707

THEN DO NOT PLACE 15K BECAUSE THAT IS NOT WHAT IS GOING THEN IT WOULD BE THE ONE WHO SAID VICTOR E TO THE START OF YOUR QUESTION GREETINGS

Your help helps me a lot anyone can be wrong ..... look at the one I think the titanic said it would never sink and without sinking he sank hehehehe a little joke

Ok victor there I do I will tell you shortly xq I have disarmed here at my table and tell you what solution there was

Responder

Ok ... I put a 1.8k and when I turned it on I opened 3 ctms of wide horizontal image ... and when I notice smoke comes out again in that 1.8k resistor and turned it off immediately before burn the horinzontal transistor

The ceramic capacitor c411 200v x 434 is very swollen I see if I have another equal to see what happens .... I will comment sldos ...

Responder

Well change that ceramic capacitor and put another one for 200v x 394 and go and see the whole image .... that was the cause so I thank you a lot for the time that I have removed
