Question about Televison & Video

3 Answers

Grundig Tharus plasma TV (110 PW 110-9410 TOP) 4 years old, now shows no picture. No warning. Just turned it off by remote and an hour or two later tried to turn it on and "nothing" just the little green LED. It has always made a muted "click" when it powers on but I notice there is another click now just afterwards at about the time interval usually taken for the image to appear. Like a switch sound. Tried turning it right off at master standby switch and wall socket. No result. Also, once it is in the "on" state with the green LED showing, it will not then respond to the remote, to be turned off again. We have had thunderstorms recently, but I have had the antenna and power unplugged during them. No trikes here though. Any clues? I note that all the internal component boards are LG !! All that money for supposed Grundig superiority. Any clues?

    OK thank you for that suggestion.
    Where would the chassis number be found? Inside?
    I'll undo the 40 or so tiny screws that hold the back panel on, again tomorrow, and look for it.
    I only looked inside carefully to see if I could spot any obvious burnouts. Of course there's not that much componentry visible without further disassembly or the chassis (not my forte).
    Also checked two slow blow fuses that were accessible on clips on a fire protection board top RHS and they show OK on multitester.
    There are no blinking LED - in fact there's blinking nuthin :-)

    Thanks Ray Williams!
    That level of inspection would be beyond me.
    Guns? Are we talking Plasma or CRT?

  • John Mobbs Dec 23, 2008

    OK, spent some time today looking for anything that might be an LG chassis #, as suggested.
    The most prominent number on a paper label in the unit looked to be on the back of the display panel. It bears the following:
    P/N 3315Q-E005A
    H4203B001026
    Model PDP42V5
    Now, much of the circuitry and componentry of the panel rear is hidden by an aluminium panel that itself holds a component board. The whole unit is built around a solid aluminium chassis. It is behind this panel that I can hear the "click" when the unit turns on and then shuts itself off.
    I think I about reached my level of competence, curiosity and safety and I don't think I should disassemble further, even though it's out of warranty and tempting, with all the Phillips head screws accessible to do so. Even if I do see something awry, It will need a tech to do something about it. A user-serviceable fuse block wouldn't be so deep in the unit would it? But at least I haven't shelled out $200 for a tech to take the back off, replace an obviously blown fuse in a 2-minute job and tell me mumbo-jumbo. I think I'm off to a Grundig service tech (if I can find one) now. Thanks to those who attempted at least some level of primary diagnosis. Any late comments also welcome.

Apparently, you were not able to view the subsequent post of Benimur, with the indulgence of the others:
Appreciate your quick postback.
Normally the chassis number would be on a sticker paper on the metal bracket. Most LG chassis number goes to something like "CA-52".
Your post "
no blinking LED" is significant. It is indicative that the power although entering the TV is not reaching the electronics, more specifically the power supply board. Aside from the 2 fuses you indicate, there could possibly be more.
Of course, with fingers crossed, you could try another outlet in the event that a circuit breaker might have been tripped.
Would look forward to your next post on the chassis number. Cheers.


Hope this helps.

    This of course would require opening the unit, perform voltage measurements,determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

It sounds very much like the power board. All the components on this board will have to be checked (capasitors etc) and re-solder all the dry joints. This board supplies the power to the guns (red, green and blue) and it is with these three colours that make up the picture on the screen. If you find that the board is faultless, then I would look at the guns to determine if the fault lies there.

Hi and welcome to FixYa,

Offhand the second click would indicate that the unit is going into protective mode. This is a result of the built-in diagnostic sensing fault in the system and to prevent further damage, halts the system. Normally, one of the LED lights would be blinking and the number/sequence of the blinks would indicate an error code. The code once deciphered would point to the probable faulty section/component.

Your post that the boards inside are LG is significant. If perhaps you can try to determine the Chassis Number, then we would have a fairly reasonable source of information as to probable faults and course of action.

Good luck and Thank you for using FixYa. Happy Holidays.

    Hi again,

    A qualified professional may be to your advantage. PDP42V5 is an LG chassis used by other brands such as Sanyo, Visio, Thomson, TCL among others. This chassis uses DGK-420W power supply board known for a faulty blue capacitor that blows. C19 Value is 1uF 630V, another is C103 10uF/50V. This PSU supplies +5, +65 and +190 VDCs. Other possible faults are the 2 power MOSFETs 32N50Q.

    Should you still have a need for:


    Cheers.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.

Would like to know the codes for a LG tv, Sony tv, and a TOSHIBA DVD ?


How to Program


Remotes With SET Button
1. Choose and press a device key i.e TV. LED will flash once.
2. Press "SET" Hold until the LED Lights up.
3. Enter the 4-digit Device code (refer code list).
4. The LED will flash once as each number is programmed at the end of the 4 digit the LED will turn off immediately if correct. If the LED flashes then something went wrong in the process. If the first code does not work then repeat the process with the next.
5. Important - Some brands use other manufacturers to make their devices if the codes available do not work the try the MAGIC search function.


Remotes Without SET Button
1. Choose and press a device key i.e TV. LED will flash once.
2. Press and hold BOTH the CHANNEL UP AND VOLUME DOWN button until the LED Lights up.
3. Enter the 4-digit Device code (refer code list).
4. The LED will flash once as each number is programmed, at the end of the 4th digit the LED will turn off immediately if correct. If the LED flashes then something went wrong in the process. If the first code does not work then repeat the process with the next.
5. Important - Some brands use other manufacturers to make their devices if the codes available do not work the try the MAGIC search function.


MAGIC SEARCH FUNCTION

2. Choose and press a device key i.e TV. LED will flash once.
3. Press and hold the SET button or if no SET button then hold BOTH the CHANNEL UP AND VOLUME DOWN button until the LED Lights up.
4. Enter the 4-digit Device code (refer MAGIC list) i.e TV is 0001.
