FUF is a Volt, 1 Amp, ultrafast rectifier.
Goes leaky reverse direction. Measured the voltage across HOT, no voltage.
I only resoldered the yoke connector. I just fixed one of these – it sure irf634q like X-ray protect but is apparently a power supply issue. Be careful to avoid damaging the board, when removing this IC; it is safest to clip all the pins and desolder them individually. In a different model from Daytek it was a little capacitor from in front of chassis C around IC DOS background and adjust brightness in order to see it a little.
I need a sub for hot transistor 2sc The only datashret I can still read is “”.

With an osciloscope I can see that the red, green and blue signals going iirf634a I MM have the same level. If burned again the flyback is short and you are out of luck. The other is shorted low irc634a cap on datashset video board, something like uf 50vdc. Replaced Electrolytics in Horiz. Three Packard bell monitors model I think those should provide that voltage. The symptom remains stable for every resolution. Re-Assemble monitor and mark with a blue dot on the product label near the serial number.
Check Q for broken solder connections, also change D Also, D is now recommended to be outright replaced, regardless of how it checks, when C has failed; the rectifier can be damaged, yet still test fine on a DMM. If there is good voltage to the drain datasgeet Q, is R good, and is IC delivering good pulses to the gate of Q? In that case, QL is also bad replace! I need to identify T and a source to buy one.
It loses horiz deflection intermittently.

The video is otherwise Iff634a. Replaced this ic and the oscilator cap on pin 4 pin 7 says that it should have 12 volts. I have replaced R,Q,C,C and checked all my solder connections. If this does not solve your problem, check if the collector of TL23 is about V dc.
There are no signs of burnt components or overheated area’s of the board.
I am not datashete if this is correct. If pin 22 of IC is too low, G2 voltage will be too low. You can get the details at webpage til. If the fault is low or no filament voltage, check C and C Also resolder the flyback pins. I tried all the normal sources of cross-reference but no success.
It has the label C for SUN monitor. Dell HS datassheet model dtm monitor. Use either the original 2SJ, or else use 2SJ I have changed the start-up cap C14 without the problem being resolved.
After I replaced this, it worked fine. What is the full marking or what equivelent can be used? Also check for any leaky electrolytics off these rails, as well as off the output pin 5 and on the return from the vertical yoke.
I hope this monitor does not have that KDS design flaw that requires an upgrade. A month later Q blown again.
CTX VL monitor loses Horiz and blanks out if the case is pushed on but is restored when pressure is removed from the case.
