I also replaced the 3 1Uf volt capacitors as they were reading low. They will run forever with cover off. I would ring flyback.

I need values for R Now there is a pincushion problem and adjustments make no difference. If there is good irr634a to the drain of Q, is R good, and is IC delivering good pulses to the gate of Q? On switching the monitor on, the fuse is blown.

If, after checking or replacing the regulator FET, it still applies excess voltage to the HOT, try checking the PC traces with high magnification, or checking the continuity of the PC traces with a meter, looking for hairline cracks.

I magnified, poked, bent, just about everything and Datasheey cannot find it. Composite Sig out Pin 3 Audio out. Voltage on ic is pin I need help trying to locate it TLF flyback.

Sony 17in gs monitor. We had two cases with the same problem caused by a shortcircuit between QL3 and the heatsink replace the siliconrubber. Number on Transformer are LAE.

Once the power has been turned off and turned on again, the user has to readjust the size and position settings, etc. Irf364a are new and the company that sold them no longer exists.

When plugged in the relays click but the machine will not power up.

Also, it is wise to desolder the bottom lead of heatsinked damper D, and check that its lead extends all the way through the board. I believe that I have the same monitor as in question, basic model no.

I need the values of D and D Poor solder connections on the vertical ic causes this problem. I have never manage to repair a monitor which has a smearing problem. Signal for horizontal output is Vpp and always work good.

I was able to wake it up by plugging and unplugging the power cord a few times, but in the process of troubleshooting this way the Horizontal output transistor shorted. Did those replaced capacitors include C disk capand electrolytics C, C; as well as the trio C, C, C, and their associated 1 Mohm resistors?

After I replaced this, it worked fine.

If power is shut off for about 10 minutes it comes back up and runs for another extended period. Daytek Daewoo DT monitor with no vertical sweep, only a bright line across the middle of the screen from left to right.

If the flyback tests fine, check the G1 and G2 voltages.

This damages Q and T Found HOT Q shorted, replaced. Video cord was subbed out with several good cords.

You can get the details at webpage til. Acer monitor has blown Q I found one of the switching FET’s damaged. I need a cross or sub for defective Q K On one contact the resistance was around Ohms when closed, and the other close to zero Ohms as it should have been. Vatasheet I found resistor R chipped it is near a pc mounting screw. Peacock Entrada 17″ Datasheeh. Magavox 20CM64 monitor, no power but there is a ticking sound from supply. Check C and C Acer N monitor starts for a second, the high voltage is passing 30K-volts, and it shuts down.

Check Q for broken solder connections.
