28-09-2009 | RX-V650 | It's not so much the setting of the speaker impedance switch, it's the intermittent switch contacts that can cause this problem.Cleaning the switch can sometimes help, but replacement is the only real fix. |
28-09-2009 | Samsung LED-LCD, pic freeze, works when tilted | I've just gotten one of those newfangled Series 8 55" with LED backlighting.
Basically, due to careless transportation it's developed some problems. I believe it was subject to 2 things: pressure on the top of the frame, and shaking back and forth |
28-09-2009 | | line drive tx is T531, line output transistor is Q533, line output transformer is T511. i have no pictures of this set as i do not currenly have one in for repair. |

28-09-2009 | Need help with testing TV components | Hi Everyone,
I have a 42" plasma TV that wont turn on. The little research Ive done points to 1 of 3 internal components possibly being bad. I need to open up the TV and test the A/V board, the PDP board, and possibly others.
Can anyone here at |
28-09-2009 | | I think this is good, i have some parts from the manual (internet) and indeed before the q533 there is a transformer, so it would be easy to aquire the q533 and the tranformer from sony, however how the q533 affect the normal operation and results in led |
28-09-2009 | | If the red/green LED blinks - you can reset it by pressining the EXIT buttom while turning POWER ON.
I have similar problem.
Originally I got spots al over the screen. Than I replaced the 1,500uF capacitor and it worked fine for a while.

28-09-2009 | | However, if i need to replace the transformer how will i ask for it at my local electronic shop as the manual which i currently posses does not describe its characteristics (only sony knows it) |
28-09-2009 | | And the model number is? |
28-09-2009 | Hitachi 51swx20b | have same problem with mine but I only have 2 stk394-160...havent tested my resistors yet |
28-09-2009 | model number | I believe the model number is GTW-P42102 |
28-09-2009 | | If you recently obtained set, set should still be under warranty. :shock: |
28-09-2009 | link to service manual | Hi again,

28-09-2009 | FINALLY FIXED | I finally got my part ordered for my tv. The swap out was fairly easy and only took a few minutes. I spent more time removing and replacing screws to get to the board than i did actually changing the board out. After all was done, my tv fired up like n |
28-09-2009 | | If you don't have any electronics experience, I would recommend that you don't do this yourself. Even with the power off and the set unplugged you can still get a nasty shock.

28-09-2009 | | Any luck getting this fixed?
I'm having the same problem.
Turns on fine and everything lights up, just no sound.
I didn't play it too loud and the speaker cables work fine when hooked to another receiver.
Possibly it got to hot, but not sure. It's h |
28-09-2009 | What to do next??? | I have a new "conclusion" regarding my problem.
The color change is not actually [color=red:9633068a59]reddish[/color:9633068a59] to [color=blue:9633068a59]bluish[/color:9633068a59] but rather [color=red:9633068a59]reddish[/color:9633068a59] |
28-09-2009 | | [quote:bb35ab8f75="minnie"]RK42 ok, RK46 bad, RK58 ok, RK62 bad, RK50 bad, RK54 bad. It's called a catastrophic failure. Change the IC's and 4 resistors.[/quote:bb35ab8f75]
how do u kno if they r bad? my multimeter is giving me a little bit higher read |
29-09-2009 | | I'm also in need of the operating instruction or owners manual. Can someone e-mail it to me [email protected] I will greatly appreciate it very much. |

29-09-2009 | | Back up to the driver IC and all the way to the microprocessor. You should be able to see some activity on the lines going to motor drive IC. |
29-09-2009 | | Well an update. I tested the caps pretty good. I did find a bad cap at C633 so that was replaced . (That is what to so long to reply waiting for parts.)Goood call D. ,But that also did not solve the problem. So any new guesses?

добре |
29-09-2009 | | Ok, firstly, i will open the set to locate the tranzistor and transformer and i will try to find them.
Thank for the worning about Next tronic
When i make progress, i will tell you |
29-09-2009 | | I'm sorry my friend.
could you be more specific?
