Re: Panasonic tc-l32c22 lcd

no blink codes, no red light nothing at all

By the way, are you getting any blink codes on the Power LED? Or is the unit completely dead.

Tom,

The 20 pin IC says H3475 OR H5475, not too sure


Jon

Tom means the number that hopefully is on the IC with 20 legs that is ringed in red on the picture. You may need a magnifying glass and try rubbing it gently with isopropyl alcohol.
If it is the same as the tv number I apologise.

Re: Panasonic tc-l32c22 lcd

Selldoor,

Thank you for the illustrations. This is starting to make some sense to me a bit now. I will continue to study until I have the Power Supply conquered, then of, course, I will have to move onto the Main board and Inverters. Hopefully

So, correct me if i am wrong. It looks as though the 115V goes to the fuse and then to the Rectifier, then to the 5V standby transistor so, if no 5V I should look to this transistor

I think i will find a properly working power supply to determine

I apologize IF i seem dumb but, I obviously am. I must be skipping some chapter or something because, I am surely missing something here


Thank you for your help in trying

I guess I will just need to study more to hopefully someday understand

Re: Panasonic tc-l32c22 lcd

if the tv worked with a new supply,but didnt when reassembled ,i would take the back off again and reseat all connector cables,(unplug and re-plug in),and making sure the psu ground points are grounded,and have a check and double check on the tv's side buttons.the little tact switches if jammed will cause this problem,if one jams on, the set will sense it and not respond to remote or the side buttons

But, at least it should have a red light when plugged in but, it does NOT

OK - let us start again. Get the power board and the main board you used when it briefly started up and post a good clear in focus picture of each side of each board.

Re: Panasonic tc-l32c22 lcd

Selldoor,

funny thing is this board has 6V instead of 5V. I also have the service manual available on Tom66 website.

Hope you can help me figure this set out. making me crazy

post a good clear in focus picture of each side of each board.

I am sorry I am not even going to try and look at them again - please can you look and enlarge them and tell me if you can make anything out of the blur. If you can then I am off to the opticians tomorrow.

Re: Panasonic tc-l32c22 lcd

Will not allo me to upload service manual

But, it is available on
tom66 website

See: http://www.tgohome.com/ServiceManuals

If this helps at all

Thank you for ANY and all help. I truly appreciate it. This set has been driving me up the wall and, ready to just scrap it

I am not very good at reading and understanding schematics yet but, will be soon, hopefully

Re: Panasonic tc-l32c22 lcd

Right - First problem - according to the SM there are 4 fuses The main one is F7001 and I can find that cos I know where it should be. The others F801 F802 - not sure why they have 3 numbers not 4 I cant see - on another board?
and F7801 looks like it should be on this board but although the pics are better I cant see it - can you?
