CT-27SX11E Fixed but need advice on R value

Check this link to know more.

Replace the parts with the original ones, a .5 ohm difference on a resistor on the video circuits will cause the unit not to work correctly.

Hi ,

Your unit is in standby mode only and can't power up because there's faulty output voltages in the power supply section. Most of the TV with the same symptom as what you've stated has a bad filter electrolytic capacitor in the output of the power supply section. It will dropped the voltage from normal and disable the unit. Sometimes it has a physical indication of fault like bulged/dome at the top but not all, you must have a capacitor checker to determine its condition.

Another caused was an open fusible resistor(low resistance resistors) in line with the output of the power supply section. It acts as a normal fuse to guard the supply from load malfunction to avoid further damaged.

Faulty microcontroller circuitry and EEPROM IC will do the same symptoms.

This symptoms needs a technical skills to isolate where the fault came from. If you don't have necessary tools and test instruments and can't troubleshoot the symptoms yourself, I would advice you to look for an experienced technician to isolate the problem.

Also, check if your unit is under warranty period/extended warranty, avail it because the manufacturer will fix it for free. Don't attempt to open the back cover, it will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Resolder the vert output IC, if this isnýt the solution you must replace the IC.

The dial could have a desoldered pin or oxydized slider contacts. Try to resolder the pins, but if that doesn't solve it then you would need to disassemble and clean the internal slide contacts on the dial which can be a bit difficult, so the alternative is to replace the dial if you can find a spare one.

To bypass the dial (with fixed resistances) you need to know the resistance at each side of the dial when it is in the position that suits your needs (connect the snare to a working input, set the sensitivity as needed, mark the position of the dial).

The resistance can be measured with an ohm meter.
To be sure that the measuring will be accurate, it is ok to remove the dial from the circuit board (adjacent components may affect the measured value).
You should do the measuring on a dial that is good.

After you've removed the dial, set it to the position that you marked previously.

Measure the resistance between left and middle pin of the dial - this will be the value of the fixed resistor which you need to connect to the left and middle hole on the circuit board.
Now measure the resistance between middle and right pin on the dial - this will be the value of the fixed resistor which will be connected to the middle and right hole on the circuit board.

Now you need to get resistors which have the values that you've measured and solder them in place of a bad dial.

It is likely that the measured value will differ from the standard fixed resistor values. To achieve the exact measured value, you can connect two or more fixed resistors in series, just make sure that the added value of the fixed resistors for each side is the same as the measured value on each side of the dial.

Now you need to solder the fixed resistors to the circuit board and the modification is complete.

If you actually decide to do this modification and you're unsure about anything, just post me some feedback, i'll be glad to help.

Anyway, hopefully it is just a desoldered pin that you need to reflux.

The problem sounds like a vertical deflection issue form what you describe.
On average they are usually in the simple repair categories. On average they would run in the $50 range if you take it to a reputable repair shop.
There are several possibilities
Bad capacitor (s)
Bad vertical IC
resistor in the power supply to the vertical circuit changing value

Brown/ Black/ Brown/ Gold It is a 100 ohm +/- 5%

i would not recomend replacing the 7w with the 5w, beacuse the resistor will allways run hot, hotter then the resistor should be. the resistor could possible melt anything that touches it & will not last as long as the original before it goes bad. find a 7w, if just for safty reasons.

The Ohms are ok but the wattage should have been the same or higher.A 1.5 with only 5 watts is not sufficient.
