Wow, nice. I did not view it in Windas Event Viewer. I found that using the original DAT data does not automatically reduce the brightness, so after WBP, I used the text software to open the original DAT and the new DAT file to compare the difference, and finally modified a single value. It has...

Yes, I found 2 very reliable methods. But the root cause is the aging of the display tube. Method 1. There is no need to calibrate. After entering das, export the DAT file to modify the G2 value to ensure that the black is normal, and then warm the machine for 30 minutes and do a color...

No matter what, I hope I don’t throw it away and try to fix it. Maybe it’s just a problem

My God, this is the largest CRT monitor in the world, produced in 1994-1995. The maximum resolution is 2k 80hz.

Hello everyone, my FW900 is greenish, and the OSD menu color is normal. I have seen many people's sony FW900s that seem to have the same problem. This seems to be a common problem. Does anyone know how to solve this problem? Is it because of capacitor failure? Can replace the capacitor to solve...

Used for watching movies?

I want to know which of Sony BVM D24 and Sony GDM-FW900 display is better? Has anyone compared the differences between them?

I also found the SONY G500 (DELLp1110, Sun GDM 5410) A board to be fully compatible with the FW900.

Yes, thanks, I have found a netizen who can be repaired

I would like to ask if there is any cable of the D board removed inside?

Hello everyone, I encountered a strange phenomenon when using windas for white balance adjustment Sony CPD-G520. When I go to step 48, das prompts to use a white image. When I display a white pattern on the full screen, the brightness of the entire screen will immediately decrease. The white...

After the Sony G500 white balance is adjusted, when the full screen displays white, the brightness will automatically decrease? Does anyone know the reason?

Hello Looking at the SERVICEMANUAL document, I found that FW900 and SONY G500 are very close in some configurations. My CRT FW900 FBT is faulty, can it be replaced with SONY G500 FBT? FW900 FBT No .: NX-4504 // J1D4 GDM G500FBT number: NX-4502 // J1D4

Does anyone know how to check the power-on time of Fw900?

I want to fix it, but there is no related accessories, and I ca n’t check the problem ... If there is really a Fw900 with good functions, I will pay $ 400 to buy it

You can buy a FW900 in China for around US $ 400. Is this a reasonable price?

Yes, I am a little impatient. :( :( :( :( :( :( :( :( :( Yes, I checked the 12v cable and 5V cable, it seems that the problem is not here, I thought the problem is these added potentiometers, so I deleted all the added potentiometers, and added the removed 100K resistor, but this did not Solve...

My Fw900 also encountered a problem and can't light the screen now ... I don't have a bad Fw900 as a part. Congratulations, Fw900 has a modular design. If the problem cannot be found, you can try to replace the module to troubleshoot the problem ... For example, directly replace the D board or A...

You can try to enter Windas -Adjustment-Failure to view the error log tips, which may be helpful to you. In addition, the interval of flashing orange light has an error code

I carefully checked the green area and found no abnormalities. Today I changed the IC404 chip (IC404 of Sony G500), but the problem still exists. Perhaps the problem really comes from the N board. The circuit of the N board is more complicated, which makes me very confused ...

No, it was n’t me. I originally had an adjustable potentiometer soldered to the R457 pin. This caused the R463 resistor to be removed. As far as I know, this potentiometer is used to adjust the G2 voltage. The potentiometer soldered on IC406 is used to adjust the color. Obviously this is an...

Thank you very much for your support all the way. I am just a hobbyist. I am not familiar with CRT circuits. I ca n’t find a repair staff nearby. Yes, my multimeter only supports 1000V measurement. I tested the G2 voltage on the A board (Figure 1). When I tested the voltage here, it indicated...

Yes, I first checked the 220V voltage, 80V voltage and + 15V-15V voltage, etc., only 80v voltage (actually 78V), others are normal. In addition, I checked the resistance of R917 is 228 (pictured)

Who can help me, my sony GDM Fw900 seems to have a problem, statement: Since English is not my mother tongue, I use google translation Problem Description: 1. This is a second-hand FW900. When it was first received, it could be turned on normally, but there was a convergence problem. Figure 1...

I re-described the problem

Yes ，Solders seems to work fine，My D board seems to be normal. Is there a problem with the A board?

It can't boot now, but das detects everything is normal

My FW900 started normally, but the menu flickered. Soon afterwards, it turned on again and found that the screen did not display after startup, but windas detected that everything was normal, can anyone help me. Test G2 (89V) voltage KB (55V) KG (55V) KR (49V) voltage is very low, because my...
