Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television

1 Answer

Pico Fuzes? I finally got the STK 392-150 IC's installed this afternoon. The set worked for about 60 seconds before it went down. I have power to the set, but nothing works. When I had the board out to change the IC's I didn't find any pico fuzes or resistors that looked burnt, discolored, etc. I did get the tech manual for it, are the pico fuzes mounted on the same circuit board as the IC's?

I have a mitsubishi 60inch model # vs 60609. the green light comes on as you turn it on but no sound or picture any ideas on what could be wrong? please help


You will need to replace IC8c00 (STK 393-110) . This is your convergence IC. You will need to measure all of the 6.8 ohm resistors, replace as necessary. These resistors will have blue,gray and gold stripes, there may be sixteen of these. Expect to replace at least three of these if not more. Replace caps C8c05 (25 volts at 100Mf),C8c07 (25 volts at 100Mf). Other caps to replace are C2c86 (25 volt at 10Mf),C2V17 (25 volt at 10 MF) and C601 (350 volt at 1 Mf). you will also need a keen eye to resolder connections behind tuner TU1A02 (says RF). Jumper sockets CE,RG,DM,VU,DP,EL. Check and resolder socket connections KC,KB,AV1,AV2 and resolder IC 2p30. And you will also need to pull the power supply board, resolder jumper connections CE, RG, DM, VU, DP, and EL. Resolder the vertical IC , this IC will be of the LA78XX series,(do not use excess solder and short the pins). Resolder the horizontal transformer, and the flyback transformer. You will need a keen eye to visually inspect bad grounds on power resistors,horizontal transistor, horizontal output transistor any any and all regulator transistors located on heat sinks. This may seem complicated, time and patience will repair this. Spend an hour a day for two weeks to fix this. Thanks for asking and show all hands of support!

Your audio output transistors are shorted and your unit is staying in "protect " mode to protect your speakers from 40 to 60 volts that is being sent at them from the shorted outputs. If you can use a meter you won't need the schematic MOST likely because the outputs are USUALLY the only parts that short out. The output transistors( or chip ) are mounted to the large, finned heatsink. The #'s on the transistors start with "2SA-" and "2SC-" followed by numbers. There are two output transistors per channel. If your unit uses an IC for audio output then the # on the IC will be "STK-" followed by numbers. These parts are available from tritronicsinc.com. Good Luck!

So.. Would the original or replacement IC be more likely to go bad again?


All the ics look identical even right down to the STK numbers. However if you didnt get the part from a authorizes Samsung vendor, chances are you got one of the cheaper made ICs. I will search for a service manual for your model. The other site I work as a tech on may have your service manual. I will check and post a link if they do.

A set beeping doesnt have to mean your CRTs are dead. Its more than likely something in your power supply. Do you have any diagnosis or soldering skills?

Hitachi 65xwx20b convergence


Your message says you "replaced stk392-150", did you replace both of the stk`s or just one of them??? One is for RGB vertical the other is for RGB horizontal, you should always replace both stk`s as a set, Hitachi recommends you use a "replacement kit"
part number X480306", this kit includes both stk`s with a new & supposedly improved set of stk`s as well as all resistors that are required for proper set-up, they strongly recommend you change all of the parts in their kit. The only other thing besides IC`s & resistors that could cause your problem is:
1) bad dcu output (you need a scope to check this)
2) you`ve lost either the +15 volt line or the -15 volt line to the IC`s, "Fxxx" chemical fuse open in power supply.
