Check pico fuses f9a04 and f9a05. They will prob be open. if so, repl conv ic's qty 2 stk392-570 . you will need pico fuses 5A heat compound, solder and iron. also check caps in dm module. if swollen, then repl. there's 4. 4700uf 50v i believe. Also check to see if there looks like something spilled on the circuit boards. if so, your picture tubes red/green or blue may be leaking coolant oily substance. If this is the case, try removing the pcb and cleaning with 97% alc. They make good cleaning sprays too. The boards may be shot. good luck to ya.

hi there,

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

My hitachi 57f500a picture went out and sound. When you power up you can hear the clicks and the red light in front comes on solid. Out of the five leds on the power board four of them are on when...


There should be a solder in pico fuse(yellow) close to that LED labled E...something. It is most likely open. If so, check to see if there is a blue high voltage capacitor(2kv) in front of the H.output transistor. If yes, replace them both...if no try just replacing the pico fuse.

Samsung HLN467W Flashing "LAMP" LED


remove the lamp and visually check if inside looks broken.if visually do not see any thing wrong,check if you have 300 volts dc supply on the ballast which starts the lamp.if you do then the ballast may be defective.if you do not then the power supply should be checked.
the lamp should always be tried first especially if is older than two years.
note - be aware about the switch at the door lamp.the door should be closed,otherwise tv will not work.if you remove the back cover,make sure to bypass the switch temporarely so you could work on the set.

No picture or sound


Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.
