Monitor model BenQ t From the above test, this Monitor circuit has voice out loud and clear that it only need the same part number with the same Hfe value unless you have some similar transistor replacement specification that is identical to the original one. Hi Roberto, Long time didn’t hear from you. Why I am getting this substrate picture, when i create a new workspace? We delete comments that violate our policy , which we encourage you to read. HI Erymas, Any voltage to inverter ic once it shutdown?

But just like any other lcd monitor when no power one have to check the fuse first and then test whether the power ic is receiving any dc voltage or not. December 29, 0.

HI Erymas, Any voltage to inverter ic once it shutdown? Sir Bemq Thank you Flat Panel Mount Interface. If the fuse have problem please check also the bridge rectifier. I used the famous Peak Atlas components analyzer to analyze both transistors and I could clearly see the big difference between the Hfe readings of the two transistors.
Jestine Yong September 7, at To my surprised the LCD Monitor starting working when the front power switch was pressed! Skip to main content. Yong, That is very beautiful countr An inexpensive general-purpose monitor deserving of its mpnitor An inexpensive general-purpose monitor deserving of its popularity by Lori Grunin.
The reason i say that was because i could see a scratch mark underneath the front LCD cover. This article is wonderful, but just that no This circuit look like it can only work with the same type of transistor that has t7055 quite exact Hfe value! Make sure no bulged e-cap and that the output voltages are good and stable.
Distorted Sine output from Transformer 6. Yes one of the trasistor C got shorted thanks for your reply Likes 0 Dislikes 0.
Repair Tips Popular Comments. Try check the backlight as a weak backlight could cause ebnq display to monittor for a second and then shutdown. Installing the transistors that have the Hfe reading of to solved the display shutdown problem. In this case, as usual after I have confirmed that only two C transistors shorted, I began to test the tuning capacitors and check the pins of the high voltage transformer.
Hi Robert, Indeed it is a very beautiful coun Eagle PCB clearance error 2.
About this product Product Information This inch BenQ monitor is appealing, pragmatic, and made for power users wanting to upgrade their computer systems. April 17, I took a blade and separate the two pins leg from shorting and i got to use a magnifier glass to help me to do the job. Plasma TV Repair Ebook. How do you get an MCU f705 to market quickly?
