You have to check (or have someone else check) the surface-mount fuse on the LCD driver board which is attached to the LCD panel at the top under a metal shield. If it's blown, you will get audio and back lights but no video.
If that doesn't fix it, then replace all the electrolytic capacitors in the output section of the power supply.

My daytek plasma TV have excellent sound but display is blurry. I changed T-con lcd controller, powerboard and Y-sus according to Fixya experts but all my efforts waste of my time.


Those 2 were also my prime suspects in your problem. Since they weren't the one then the only part left that could cause that is the tuner and the IF section but , to be honest ,  it's been a long time since i've heard that one of them has failed. Start by checking all internal connections, a data cable could be lose and that is more plausible.

My maxent TV has no picture and no sound


If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

Daytek DT3220 power button flashes green 4 (5) times, no picture


The power supply voltages might look good on an oscilliscope or using a DC meter, but that doesn't really tell you if the supply is good.

Your TV has an unusual symptom, however 99% of the problems on these TVs are caused by the power supply. I have had 3220s that won't power on, the remote or controls on the TV won't work, or the unit blanks out and all sorts of other odd problems. The power supply can test fine, but if you substitute it the TV will work fine.
Sorry to say you're up a creek. The good news is that just about any 5,12,24V power supply for a 32:" TV will work if you are comfortable rewiring the connectors. I have done this a few times and rescued the TVs from an early grave (I'm actually just about to start on another one now). The pinout is written on the board, and make sure the power supply you want to use also has the pinouts marked on the board.

I have a Daytek DK-321A. The picture turns off after turning the TV on for 2 seconds. Sound and channels are fine.


This TV has only 3 boards - power supply, inverter, and main/controller boards. Most likely it is the inverter board - i.e. no backlight. If you still have sound, the power supply is on,

Daytek dt 3220 will not power on


OK, your Daytek 3220 is not a projection TV, but an LCD TV.

Second, I hate to say it, but you bought a piece of junk. They have excellent pictures when they're new, but after a few years capacitors in the power supply go bad. When this happens, either the controls and remote stop working, or the TV starts blanking out, or it will just die and never work again.

The solution is to go buy a new TV. The power supplies are no longer available, and even if you could get one very often the faulty power supply has damaged the main board and/or the LCD panel.

In about 5% of these cases, replacing the capacitors will get the TV to work, in about 25% it will get the TV to work, but because the main board has been damaged the TV will intermittently blank out. In another 25% the LCD panel has been damaged so once repaired you will see dark streaky patches across the display.

In the rest of the units you could have all three problems or any combination of them.

It'ds really too bad because they use a Samsung panel, and have excellent pictures when they're working.
