Be sure to use an ORIGINAL Sony transistor and be sure to resolder the pins of the small horizontal driver transformer and all parts connected to and around it, and your set should be fine.

SOURCE: need circuit diagram for bush

Diagrams i am sure as you know are not always easy to come by, at least for free. I see that there are available boards online and a company that will rebuild this model of power board for you in UK. is where it is at. looks like $80

I have Panasonic CRT TV, Model No. - TX-32WG25X. The main problem is that in half screen of TV horizontal lines are appearing along with picture and sound is not coming

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Panasonic TX-P42X10B wont turn on - goes into standby

Hard to troubleshoot with just this info, the red light can be helpful if its 10 blinks repeating over and over replace the power supply first then the A board. Voltages check on the power supply would narrow down the culprit.
Post again if you measure the power supply voltages

The tv is a 32"

The horizontal output transistor of your RCA TV has shorted. Horizontal output transistor is one, that drive the Line Output Transformer [LOT] in short, which gives voltages requred to the picture tube of your tV. There are mainly two resons for this transistor shortage. If the above said LOT has shorted [a winding short in between at its inner side; and is irreparable]; and for some other reasons which cannot be predicted. First replace this transistor, which can be located very near to the LOT and will be screwed onto a metal heatsink to radiate heat away from it while working.
It will be three terminal black component. Replace it with same type and number, and switch ON your tV for a short time, say 4 seconds or so; unplug the device from AC mains wall socket, touch the replaced component with bare fingers and feel the heat. It may be slight warm, bu not too hot. If LOT has damaged, this transistor also will heat up, and a whisiling sound will be there. If so; never switch it ON again; replace the LOT and it is damaged. OK.

When switching panasonic tv on it goes into standby

It is for sure that your set has encountered a fault in the power section in the main board. There could be either a failure or a break in the circuit. So first of all open and check the main power board for any signs of dry soldering joints. Use a good soldering iron and a good light to probe. Solder all possible areas specially ones closer to the power resistors and drives. next check the +B voltage, trace it or disconnect from the ddrive to confirm the failure. You must use a good multimeter to check from the power section which is working and is cutting off due to a failed feedback. If not familiar do not attempt but take help. I hope you can decide and try. Good day

I have a Model DX-R24TV suddenly it wont come on green power "on" light flashed and now I hear clicking inside what is it and where can I get parts?

The clicking noise you are hearing can be from the HT power section. The Main power is trying hard to switch on the set but the feedback signal is missing to the SMPS-switch mode power supply- that makes the protection to cut and power. You will need to check onthe EHT, the line output transformer, the EHT driver transistor and the allied ccircuits for any short which is making the +B cut off. check onthe high voltage capacitors, the vert output also for any short. replace the shorted component. The spares must be tried for availability in the nearest spare shop. If it is the EHT you must check and decide with the price of a new one. I hope this helps. Good day

Panasonic TX-29ps stdby LED only 2 seconds after switching to the network, everything else is dead. However, Switching PSU IC801 provides voltage to 5V for stdby.

check : H-output tangester / EHT output voltage line 12v /24v 180v check dyiod /capaciter / ragistance ..
if your tv set red led is cantinu on then standby tr.checked if ok then
cheked 5v ragulater ic or prosasor cristl and with canecting pf tr. check pin voltage
if ok
then check EHT output section h-driver transfermor h-puls 2.1v ac
if not then check croma ic input voltage B+ is 8 v dc and canacting spaer.

Hi, I have a panasonic tv model tc21xy3 standby power only red liht can you give a solution of this trouble pls.

Your Tv Horizontal deflection doesn't work, try to switch ON your TV by remote control or by pressing the program up or down button in the TV set. If still working check the B+ in the capacitor rated 200Vdc. monitor the voltage as you press the program button, it must have a 90vdc , or remove first the Horizontal Output Transistor before you switch on the Tv. Then monitor the Voltage in B+. If it is present your Power supply is good, if not then check the component in Power supply section. if the B+ is present check the horizontal area.

Panasonic model TX-29GF10X, went on stand by , and not Switching ON again, what is the majore cause?? or what does the TV need to restart again

Your problem im afraid could be one of several things. Power supply problems,sweep supply,horizontal output transistor,standby power supply. The best thing for you to do , if your not a tech, take the set into a reair depot as these are solid state sets and have no user replaceable parts inside. Good Luck
