Question about Mitsubishi WS-55513 55" Rear Projection HDTV

1 Answer

Rechecked the conections and still

Hi..rechecked everything and no bad connections, etc.. so I have since pulled the entire circuit board assy from the TV chassis and am going to try and troubleshoot from component level. Seems like a short somewhere but not too familiar with this model. I have a service PDF of the model, any suggestions where to start?

Thank you in advance!

Well..that's interesting...before you begin, have you determined a source for replacement components? I'd be hesitant to do all that work, NOT knowing if there are readily available form fit function components for it. Don't assume that overseas manufactured appliances have a ready distribution system for spare parts.

Mitsubishi tv model VS50VA1 pix goes black but still has sound


I have fixed a lot of these sets.

The most common thing that happens is the set develops what we call cold or bad solder connections.

The circuit boards were not ever soldered by hand but by machine--everything soldered in one motion.

I have seen a large number of these where once the chassis (frame with the circuit boards) is pulled loose and tilted so bottom of all three boards face the rear of the set it is usually a 15 minute job to locate and re-solder cracked connections.

The most common area is the power supply board but almost ALL the bad connections are easy to see with your eyes.

If you cannot or do not know someone capable of this it may not be worth a shop repair---very good set but many major parts are NO LONGER available.

Soldering should cure the problem and I can if you have some skill (or someone you know does) point you exactly where and what to look for.

The reason for the bad connections is simple: the boards heat up and expand and when they cool they contract and the heat from some parts causes connections to literally crack loose.

Let me know if I can assist you in any way, I am here to help you.

Regards, SD TECH

I have a DLP Samsung HL-R6167w and it's not working


I had a bad digital board also. I went to parts.com to order a new part way cheaper than from repair service. the only problem I had was that after installation which is super easy 4 cables to unplug and replug. when I turned on the TV the picture came in upside down, not good. no one would give me the code to flip the screen as it is in a hidden menu, well after months of searching the web I found it!! It works for most all newer Samsung TV's. turn the TV off, hit mute then 182 and then power on button on the remote. the "hidden" menu will pop up and you scrool down to h-flip and flip the screen. I don't recommend messing with any of the other setting as you could likely really jack up the TV but at least you can fix it for a 3rd of the cost you would spend otherwise.

RK46 Changed - Still have clicking diode then the board dies.


I would check the standby voltages and see if they are correct and then move on from there. The flyback will usually have signs of heat around them, however that model really isnt famous for trouble some flybacks. I would check the supply voltages for sure that could give you a better leg to stand on as far as determining if a repair tech should be called in or not

Pioneer Elite PRO-520HD wont stay on


It is most likely just solder connections on your power supply. If the only diag LED that lights is on the supply, then thats usually the case. You can unplug the set and remove the supply to fix it with a little soldering. You have to remove the metal board supporter from the bottom of the board and solder quite a few connections. Look for cracked connections on the power connectors to the rest of the set, and also connections on the main transformer. If you need soldering experience, get a kit at radio shack and build a little project to get some practice.

Toshiba 50H81 Has Power but No picture or Audio


ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

Amps and resistors


The IC is no doubt bad due to powering it up with the solder bridge. may possibly need entire convergence board unless you have the service manual and troubleshoot it.

NO PICTURE AFTER FEW MINUTES/DARK PICTURE/ERRATIC/NO MENU VISSIBLE


Most projections have a removable speaker cover on the front under the screen. Then there is an access panel that you remove the CRT sockets are the circuit boards attached to the CRTs
