I have a Hitachi 43UWX10B that won't turn on. When I try, the red power light flashes, and I hear intermittent chirping. Any way to verify the problem and estimate repair costs?

Your convergence chips have failed.

Sometimes when they fail the TV will look 3D or distorted and sometimes it will just loose video and audio and chirp.

This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly. 4) TV Chirps

The Power Light is Red

yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Won't power on...

Unplug the TV for a minute then plug it in while observing the power light. If the light flashes three times then the standby power supply is OK.

If the standby power supply is OK, a diagnostic code can be read from the green power light by counting the flashes. Press the power button once (this sets the diagnostic code). Press and hold the INPUT and MENU buttons on the fron panel for 5 seconds then release. The green light flash a two digit code (x flashes, followed by a pause, then y flashes). If it flashes a 2-2 code then a short circuit has been detected in the switched power supply. It would normally flash a 1-2 code for "no problem detected".

If a 2-2 code is read, check for blown pico fuses on the POWER circuit board. If the FA904 or FA905 fuses are blown then most likely at least one of the two convergence driver ICs are bad. It seems like this is the most common failure. I replaced these fuses and ICs in my TV. The parts cost me $50, but it required extensive disassembly, PC board desoldering & resoldering, and reassembly. If you can resolder circuits on a PC board then you can probably fix it yourself, otherwise call a repair person.

Thomson DTI6300-16 digital TV recorder frozen, red light on constantly, no resposnse to any commands. I think it needs a factory reset - how do I do this?

Try Resetting the box to its factory setting:
  • Menu > Setup > Help
  • Then press the Green Button (Even though it doesn't show as an option)
  • Then press the Red button for a full reset
Warning: You will lose all data on the Hard Disk!

I did this when mine wouldn't record anything and dumped all my pre-recorded programs.
Worked a treat.

Thomson dti 6300 freeview box will not come on just shows constant red/orange light flashing all the time, tried leaving power off etc....anyone know?

What to do: if you have a solid amber light If the power light on the box will not change from solid Amber to solid Red then it is possible that a problem has occurred with the current in use software. Before attempting a fix, power the box off and on at the power socket and then wait at least 5 minutes for the solid RED lamp to appear.
If it still remains solid Amber and the box will not come out of standby to ON (Green light) then this can be corrected using the software revert procedure which is done using the box front panel buttons as follows:

1. Remove power to the unit by removing the power cable from the back of the box.

2. Wait 20 seconds and then restore the power cable while pressing the standby button repeatedly on the front panel of the box.

3. Release the standby button immediately when you see a lamp flash on the box's front display, and then immediately press the following front panel arrow buttons in this sequence:

- Menu
- OK

Note: you have to do this quickly and in sequence

4.The Orange light will flash and the STB will then reboot and should return with the previous version of software.

5. The box will now be running with the previous software version but it will automatically update with the latest version within approx 2 hours and you will be notified by message which will appear in the Message area within the Main Menu.

If you're still having problems please call 08444 159 159 and a member of the Technical Team will be happy to help.

Flashing Power Light

This set is going into shutdown. It has a safety feature that will not allow the set to turn on until it checks certain circuits. Inside the set there are multiple Red LEDs and one green one, that light up at turn on. One of them is not turning on and thats the circuit that needs repaired. The most common I've found is the Horizontal Output circuit. Usually the fusible link on the secondary in the power supply. Sometimes it goes as far as the High Voltage Transformer. Of course this is just one of the possible four circuits that cause this symptom. Hope this helps.

Flashin power light - wont come on

The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
