Help...Philips Plasma TV error code

[zukitough]

I have a flat panel tv made by Philips. It is a plasma. On the power LED, I have 1 long red flash and two short red flashes. This means an error code of 12 I think. with the following chart the code is a "Histogram (YUV) (IC 7770) error". What hell does that mean and how do I fix it?

chart:Here is a list of the Phillips blink codes. THese may be different for your model but will likely be in the service manual.

0 = No error
1 = X-ray protection, E/W protection, and/or Vertical protection active
2 = High beam current protection active
3 = Reserved
4 = +5V protection active
5 = Signal Processor (IC 7150) register corrupted
6 = Signal Processor (IC 7150) error
7 = Total failure
8 = Internal RAM error (Microprocessor IC 7000)
10 = NV memory (IC7088) addressing error
11 = NV memory (IC7088) size error
12 = Histogram (YUV) (IC 7770) error
14 = Sound processor I²C error (TDA9855)
16 = Main Tuner I²C error (IC 1125)
17 = PIP Processor I²C error (IC 7350)
18 = PIP Tuner I²C error (IC 1127)


I am in Iraq so I cant just take it back to Bestbuy or whatever. If any of ya'll know a TV repair man that can tell me what this code means as far as fixxing the TV, please post up. Google has taken me in circles for hours.

What model is your tv?

[desertkrawler]

And do you have all firmware upgrades?
You can also email Philips direct, it seems they don't want their trouble codes out there
But the exact model is by far the best place to start.

42" Plasma
model # 42PF7520G-98

I found more than a few responses that said firmware would fix it and it was a common update issue.
Try that in the meantime and I'll look some more.

I searched some more and found out your fawked
Apparently philips tv's aren't very good or user serviceable in the least.
Believe it or not I found this reccommendation to try more than a few times I suppose it's a testament to their build quality

HARD RESET: Unplug the power cord for 4 hours; then power back up again.

WHACK CHECK: This is to determine if the cause of the problem is a loose connection or cold solder joint (which is about 50% of causes across all sets.) Just whack or smack the set with your hand or fist all around the cabinet top, back, sides, etc. This will sometimes restore the connection that is acting up.


Sorry I couldn't help more, hopefully in a bit a philips tech will wake up and log on.

Thank you for your service.

Edit- Just in case your wondering the light only indicates a fault inline voltage and to diagnose further you need to pull the back cover off and manually change circuits while hooked into a puter.
From what I understood anyway

Thanks. Those were all my next troubleshooting steps. I work with "special" and "unique" electronics everyday over here, it's why I am deployed. I may try and scare it with a BFH next. Plasma's aren't my specialty, more like audio stuff, NVGs, duplicators and radios

I hope a good whack fixes it for you, it would seem there's a good chance of it as nothing in the military is used lightly and something probably got shook loose.

A quick search in the AVS forums shows a lot of problems with Philips plasmas, which is in line with what I've seen in hotel installations.

I unplugged it for the night to re-set the memory. I also sat a BFH next to it and told the TV if it didnt fix itself by morning then I was gonna fix it with the BFH. I know it doesnt make any sense but believe it or not, I had a CW4 show this trick to me on a SINCGARS radio and by God it worked the next day.

This wasnt bought because of durability and besides it isnt like the army can get its money back. The officer in charge is in a position that comes across alot of good free shit that people dont want and I am pretty sure if we can fix it for him then my team will get put on the "notify 1st if cool shit is found" list. People are always asking that unit for free shit, but no one but my team has asked how can we help them. Plus it is always good to make friends and my guys need some on the job training on some regular electronics. .
