Gentlemen of me I have a very good morning, the problem I have with this TV is that when the screen rises a little the image begins to undulate and if I increase the image more disappears leaving the return lines, when doing this the voltage does not change Well, I thought it could be the source, I changed the flyback and it remained the same, what else can I check. Therefore, I expect from you a light to help me solve this problem. Thank you so much SERVI-PECAS

Mr. franciscovallai, the reason for increasing the screen is that the screen is very opaque and when the screen is enlarged a little, the image begins to undulate as if it were the source, it has already been reviewed and is working in perfect condition, for this reason I decided replace the flyback without favorable result the 200v capacitor was changed for the video on the screen with the same result
Thank you

suggestions.- 1.- comment how much you have of b + .- 2.- you remove the flyback and the hot, place a focus of 75 / 100w of the b + to ground, with this we will check the source and this will have a load.- 3. - Connect the generator and adjust the screen and focus. - If you do not have a generator you can go to a cyber and have a cd with color patterns, grid, dots etc. etc. 4.- If the b + is in its voltage, check the filters with an esr meter, if you do not have a TV b / n that is isolated from the network and has a transformer driver can be made of a tester.- 5.- With the grid you will have the certainty if the undulation is vertical failure or power failure. comment. greetings.felipe ascencio

Mr. Felipe Antonio, following his advice, I checked the capacitors of the source with the ESR and found the secondary source capacitor a bit devalued. I changed it. This was the solution to my problem.
Thank you very much for your advice.
