Hasbro R2D2 Interactive robot circuit.

Hello Robotek,

I am looking for a schematic or block diagram to help me repair 4 R2D2, There are 2 Microprocessors involved, op amps, comparators and an analog multiplexer. The 2 pcbs have surface mounted components and are tooooo hard to trace. I have been unable to get support from Hasbro, and unfortunately do not know the name of their supplier.

Do you have a source to shed some light on the schematic or block diagram?


Ontario, Canada.

Sorry Ron, dont have the information you require. What is the problem with the R2 unit. Can I assist you in fault finding? Multilayer boards make servicing difficult indeed, it may even be an interlayer connection causing the problem. If masked processors were used, parts may be difficult to get. Have you checked things like DC/regulator conditions, reset devices to micro's, clocks working and so on. More involved repairs are hard to acheive on any modern firmware controlled equipment.

First I would like to thank you guys for your help, I have not electronics for quite some time until my daughters LCD TV went out and I found this sight and was able to fix it with no problems, so thank...

Check first that you are operating the Amp properly, and that the channels are not muted.

Then you will need to test components on board following the diagrams on repair manual.

I will see if I can find any diagram for your model.

Where can i get a schematic..

I've also been looking HD500 schematic, but never got it.
You can use X3L schematic as a reference and compared.
Some sections of the X3L diagram, similar to the HD500.
By the way, what is the problem with your HD500? Maybe I can help or share.

Hello,I need schematic diagram for tv general

Interesting request. When I was first starting out I got books from the library on TV circuits, block diagrams, etc. In general the block diagrams really helped, the circuits not so much since as soon as they are published they're obsolete. If you're looking for schematics on the new digital TVs I'd guess that I'd ask the manufacturer for the service manual and be prepared to spend some money on it. I used to buy the service manuals for all my TVs since I got them as hand-me-downs and usually had to repair them to get them to work again anyway. We bought out first color TV (new digital TV) in 2012 and all I've heard is that no one repairs these TVs any longer, not completely true, but when was the last time you saw a TV repair shop in your town or city? Try the library for anything on TV circuits.

How do I fix a blown op amp on fender hot rod deville 2x12?

Unless the person that analyzed this problem used an oscilloscope and did detailed troubleshooting, I would NOT jump to the conclusion that aan op amp was blown BASED upon my looking at the schematic of the unit. There are MANY components involved with the overdrive channel, including relays and other transistors and components. The most probable caause would be that 1/2 of the V2 vacuum tube is burnt out. Test by swapping V1 with V2. If NOTHING works, then replace the tube that is NOW in V1 as the second section of it has a burnt out heater. Also a bad potentiometer for the OD channel would be a suspect. A VERY common problem is broken solder at pot terminals. Try plugging a set of headphones into the preamp output. See if you can hear sounds in bothe OD and clean channels. Note you will only hear sound in the LEFT headphone as the preamp out is MONO. MOST of the three op amp chips would NOT kill the OD signal if they were bad.

Hello ! one channel to have any high frequency oscillations. After few sec after ON , LEDs TEMP & ACS and relay disconnecting speaker . Regards Jerzy Purtak

One of your op amps is probably gone or there's a bad capacitor somewhere.
Get an oscilloscope and trace the oscillation from the output back towards the input.
When you see clean signal on one side and oscillations on the other side of an op amp, that op amp will need to be replaced OR if you see bulged or leaking capacitors around / connected to that circuit, they will need to be replaced.
Also look for damaged driver transistors between the clean and oscillating signal.
A schematic will be extremely helpful in these situations!
