Phillips 52PFL5704D/F7 main board

[whatusername]

This is gonna be a tough one guys..
I picked up this 52" lcd tv for a price so good i would be crazy to have passed it up But... the tv does not have the main board. according to the po the board broke they sent it for repair got it back then it broke again they sent it out again but this time it could not be fixed so they got a refund and wound up with no board.. I searched shop jimmy and it says there are 6 different main board this model could possibly use. how can i identify the correct one without the old one?

i called Phillips i swear they hire any moron they can find to answer the phones and read off a screen.The so called Tech said he was looking at the website for the company that makes their boards but the main board is not available because they don't have it on the website so he couldn't even give me a part number. I asked for the website and he tole me its Encompassparts.com so i go in and boom find the main board ez breezy. now i know the correct number is what i had found before. (A9PH1D1G-003) now to buy a board

Revive.. so i never got my board i ordered i got a refund. i found the same tv a few months back on cl claiming bad tcon board i bout it for 60 took main board put it in mine and powered on beautiful picture. problem is this tv has the speakers on rear cover and some metal connection on chassis that touched the rear speaker contacts and gives it sound.. well the plastic that holds the metal tangs on the chassis part broke so i had no sound.. then stupid me i took main board and tcon and put it in other tv and powered it and got half acreen of vertical lines other half fine. then i switched it back to the other tv again and now have same issue as the other one with half lines i have tried reseating ribbon cables like 10 times i swapped lvds cables cleaned contacts im going nuts with this tv.. i actually got frustrated and didnt touch it for like 3 months but today i messed with it again and its still giving me the same issue half screen.. WTF did i do wrong?

Re: Phillips 52PFL5704D/F7 main board

How many ribbon cables between the LCD panel and the T-CON, 2 or 4? Already try re-seating them again?

[whatusername]

Re: Phillips 52PFL5704D/F7 main board

2 and tried reseating them countless times also checked tab bonds no difference except when i removed ribbon cable on right side of tcon the screen turned white on that side

"when i removed ribbon cable on right side of tcon the screen turned white on that side" That is what to expected. see post 10.

I had a Plasma and when I did not discharge the Va power to the lower driver boards before disconnecting and reconnecting the ribbons to the control board it caused the new vertical lines problem,thus blowing the T chips inside the plasma panel.

Dont know if this helps being you have an LCD but thought I wouldl share.

Re: Phillips 52PFL5704D/F7 main board

ok bud so u say bad panel thats ok i took all board off it and trashed the panel and casing but remember i had 2 and both did same thing.. so i will put the tcon and main in the other one and see if it works or still does the same thing.. i thought mayb bad tcon but who knows

[budm]

Re: Phillips 52PFL5704D/F7 main board

Yes, do put that T-CON and see if it does the same, it is very hard to be 100% correct to say if it is T-CON or the TFT driver IC in the flexible PCB in the LCD panel assembly.

Re: Phillips 52PFL5704D/F7 main board

install parts in the other tv and it did the exact same thing as the first one.. i got a feeling i tossed a perfectly good lcd panel but dont matter cuz i needed the room anyway.. so bud what are the steps to test the tcon? i think it may be my problem

[budm]

Re: Phillips 52PFL5704D/F7 main board

You have 2 TVs and 2 T-CONs, and both T-CONs are doing the same thing? Too bad you did not try the T-CON from the second TV on the one you got rid of.

Re: Phillips 52PFL5704D/F7 main board

had 2 tv 2 tcon but one tv needed main board other needed tcon i took main and put it in tv with good tcon and had nice picture but no sound due to speaker connections being broken so i removed boards and may have mixed up tcons not sure and put it in other tv and had this issue. but the other tcon i had trashed already so i couldnt test it then i swapped parts again back to tv with no sound and still same issue thats is the one i trashed today so now im back to square 1

Re: Phillips 52PFL5704D/F7 main board

so all in all i need to repair this tcon to keep it cost effective because i bought 2 tv to make 1.. i already have a buyer if i can get it working but a used tcon is $95.00 plus $100 i got into the tv's its getting up in cost
