Plug fuse blown, 2 x 10R 5W resistors o/c (R003 & 005) caused by transistor K2843 s/c all in power supply.
I failed to note the cct reference before putting it back together (!!!) but there are 3 or these on a large heatsink that almost covers 2 x large caps.

Yes it has a AC fuse you can check it but I have not seen one the was open. I think your problem is in the SMPS.

Sound but no image on Hitachi 42pd5000


Two things need to be checked. The ballast board and the T-con board. Shine a flashlight on the screen with the TV on...If you see a faint picture moving, then the T-Con board is OK. The ballast board for the white backlight is bad. If you don't see a faint picture, then the T-con board is bad.

Passenger power window not working on 2002 Saturn L100. Fuse OK, so is relay. Anything I am missing?


Hi Lance

Just a process of elimination

Run a power lead from Battery directly to motor & test.

Cable to motor may be broken internally from flexing at door joint?

Good Luck

Hi

Please try this trick: when the TV is off, bump both sides with hand palms at the same time. If the set comes on, you have some dried solder joints in the board. You shoul ressolder them specially on the areas where heavy components are placed: switching transformer ans its MOSFET transistor and flyback transformer and its associated circuits and the small pcb attached to the CRT neck.
Good luck.

TV cannot turn on


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Action-3: Replace the main board!!!

Hitachi LCD TV Dead


There is a internal fuse on the power supply board. When you plug in the set, does the standby light come on?

My hitachi plasma tv model 42PD5000 wont turn on.the red light by the switch wont turn on either.i have checked fuse on plug which is ok.please advise what may be the problem. Thanks Roberto


Hey,

A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.if otherwise, the power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this will help to fix the problem and do take care in handling the problem.....

Tv wont turn on


Check the ff:
1. Power plug - for open internal wire due to frequent bending,pulling.
2. Try to power by remote - if power up by remote then you have a faulty tack switch.
3. Replace Internal Fuse - sometimes because of power surge the fuse fail. However if the fuse blew again this is an indication of shorts.
Next step is not Diy because of the ff reason
3. Voltage regulator - might be open or shorted.
4. H-out transistor - shorted
5. Open fusible resistor in line with the B+.
6.Dry joints

Thanks for using fixya.
Pls rate my help.

I have a hitachi 42hdt79 and yesterday the power just went off. the power button on the tv does not power it on nor does the remote. just dead.


The internal fuse, if you are lucky, may have gone. It is situated before the on off switch and mains filtering circuit board.

[BRAND SPECIFIC][TOSHIBA][QUICK FIXES]
Flashing LED
<< Back to Quick Fixes Page
If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.
