Question about Sanyo PM-8200

1 Answer

No signal after replacing screen and casing...

My Sanyo screen had been smashed So, I replaced the the whole top part of the phone along with the rest (I switched everything, but I kept the same board.) Now I cant seem to get more than 1 bar, usually the phone will have none. What happened?? I was wondering if it was a compatability issue, or if it is an easy fix?? Please anyone, I cant stand not being able to figure it out myself... I appreciate ALL help! Thanks

I would double check all the connections. Sounds like the antenna may not be connected properly.

My Sanyo DP46819 TV screen is getting darker toward the right side of the screen and distorted, also sometimes has shadows move across the whole screen. What will fix this?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Sanyo model number DP46849 half the screen is black

This is a problem with the ribbon cables taking the signal to the various parts of the panel. The cable is bonded at the factory. That bonding has failed in one part of the screen.

Unfortunately, the bonding can't be fixed with just a blob of glue. If the ribbon cable is removed then it will never work again. The connections are too fine.

The answer is to use some neoprene tubing to put light pressure on the connection. This is done by opening the case and inserting the neoprene like a round wedge.

I have a nokia n95 and my screen started flicking and started going funny.Sometimes the screen doubles up the picture and then went off and buttons freeze.Its not broke or smashed.Over the last week now i...

Hello,

The problem is not from a virus or a software update. It is a hardware problem, the problem is that the flex of the phone is weak, that is why it is acting that strange.What You have to do is to replace the flexi ribbon that connects the screen to the main board of the phone. To do that, please follow the steps below:
  1. First remove the battery cover, battery and memory card. Move the slider down and remove the two screws you see.
  2. Now move the slider up and remove the two screws at the top of the phone.
  3. Run your fingernail along the edge of the join of the front cover to unclip it.
  4. You should now have the front cover removed. The keypad should be loose as well.
  5. Flip the keypad part back to access the ribbon which connects the LCD to the phone.
  6. The screen is attached to the circuit board by a ribbon which attaches like a plug and socket. Simply lift the connector up to unplug it.
  7. Take off the screen,
  8. Disassemble the rest of the phone to be able to gain access to the back of the socket where you disconnected the screen from,
  9. It is the relay ribbon that is the flex,
  10. Replace it with a new one and reverse the process to reassemble the phone back together.
That is how to replace the flex, after fixing the flex, the phone will work perfectly fine once agin. Hope this helps. Thank You for using FixYa!!!

Screen is smashed on 42"

You sure can, but I doubt you will find one at a decent price.

It is more likely you will find another TV with a different defect and fix it using the parts from yours than barely finding a replacement screen.

Plasma TVs are hard to disassemble because of the more stable construction needed in the first place due to the heavier displays. LCDs are a whole more easier in this regard...latest Chinese models don't even have a chasis, they have the LCD mounted with screws directly on the plastic cover...it SUCKS...but that's another story.

In your case, it's not only going to be easier to find a TV with a different deffect and intact display, it is also probably the only financially meaningful option available.

That's at least our experience. Do not kill the messenger...but vote for his answer :-)

Call Sanyo for warrenty repair,tv is less than a year old.The problems,u discribing could be cause by the Tuner board,that the board,where the incomming broscasting signal cable plug into it.Worse cause,the LCD picture screen is shorting out and dying,than the tv is not worth repairing.The LCD screen panel are 90% of the tv,will cost the same as a new tv,if the LCD screen panel was to be replaced.Sorry,than the tv not worth as a whole tv any more,only as electronic's boards for parts,that it.
